• What is a PhD?

Written by Mark Bennett

A PhD is a doctoral research degree and the highest level of academic qualification you can achieve. The degree normally takes between three and four years of full-time work towards a thesis offering an original contribution to your subject.

This page explains what a PhD is, what it involves and what you need to know if you’re considering applying for a PhD research project , or enrolling on a doctoral programme .

The meaning of a PhD

The PhD can take on something of a mythic status. Are they only for geniuses? Do you have to discover something incredible? Does the qualification make you an academic? And are higher research degrees just for people who want to be academics?

Even the full title, ‘Doctor of Philosophy’, has a somewhat mysterious ring to it. Do you become a doctor? Yes, but not that kind of doctor. Do you have to study Philosophy? No (not unless you want to) .

So, before going any further, let's explain what the term 'PhD' actually means and what defines a doctorate.

What does PhD stand for?

PhD stands for Doctor of Philosophy. This is one of the highest level academic degrees that can be awarded. PhD is an abbreviation of the Latin term (Ph)ilosophiae (D)octor. Traditionally the term ‘philosophy’ does not refer to the subject but its original Greek meaning which roughly translates to ‘lover of wisdom’.

What is a doctorate?

A doctorate is any qualification that awards a doctoral degree. In order to qualify for one you need to produce advanced work that makes a significant new contribution to knowledge in your field. Doing so earns you the title 'Doctor' – hence the name.

So, is a PhD different to a doctorate? No. A PhD is a type of doctorate .

The PhD is the most common type of doctorate and is awarded in almost all subjects at universities around the world. Other doctorates tend to be more specialised or for more practical and professional projects.

Essentially, all PhDs are doctorates, but not all doctorates are PhDs.

Do you need a Masters to get a PhD?

Not necessarily. It's common for students in Arts and the Humanities to complete an MA (Master of Arts) before starting a PhD in order to acquire research experience and techniques. Students in Science, Technology, Engineering and Mathematics (STEM) don't always need an MS/MSc (Master of Science) to do a PhD as you'll gain training in lab techniques and other skills during your undergraduate degree.

Whether a Masters is a requirement for a PhD also varies by country. Australian PhDs may require a Masters as the equivalent of their own 'honours year' (where students work on research). US PhD programmes often include a Masters.

We have a whole guide dedicated to helping you decide whether a PhD without a Masters is the right route for you.

The origin of the PhD

Despite its name, the PhD isn't actually an Ancient Greek degree. Instead it's a much more recent development. The PhD as we know it was developed in nineteenth-century Germany, alongside the modern research university.

Higher education had traditionally focussed on mastery of an existing body of scholarship and the highest academic rank available was, appropriately enough, a Masters degree.

As the focus shifted more onto the production of new knowledge and ideas, the PhD degree was brought in to recognise those who demonstrated the necessary skills and expertise.

The PhD process – what's required to get a PhD?

The typical length of a PhD is three to four years full-time, or five to six years part-time.

Unlike most Masters courses (or all undergraduate programmes), a PhD is a pure research degree. But that doesn’t mean you’ll just spend years locked away in a library or laboratory. In fact, the modern PhD is a diverse and varied qualification with many different components.

Whereas the second or third year of a taught degree look quite a lot like the first (with more modules and coursework at a higher level) a PhD moves through a series of stages.

A typical PhD normally involves:

• Carrying out a literature review (a survey of current scholarship in your field).
• Conducting original research and collecting your results .
• Producing a thesis that presents your conclusions.
• Writing up your thesis and submitting it as a dissertation .
• Defending your thesis in an oral viva voce exam.

These stages vary a little between subjects and universities, but they tend to fall into the same sequence over the three years of a typical full-time PhD.

The first year of a PhD

The beginning of a PhD is all about finding your feet as a researcher and getting a solid grounding in the current scholarship that relates to your topic.

You’ll have initial meetings with your supervisor and discuss a plan of action based on your research proposal.

The first step in this will almost certainly be carrying out your literature review . With the guidance of your supervisor you’ll begin surveying and evaluating existing scholarship. This will help situate your research and ensure your work is original.

Your literature review will provide a logical jumping off point for the beginning of your own research and the gathering of results . This could involve designing and implementing experiments, or getting stuck into a pile of primary sources.

The year may end with an MPhil upgrade . This occurs when PhD students are initially registered for an MPhil degree and then ‘upgraded’ to PhD candidates upon making sufficient progress. You’ll submit material from your literature review, or a draft of your research findings and discuss these with members of your department in an upgrade exam . All being well, you’ll then continue with your research as a PhD student.

PhDs in other countries

The information on the page is based on the UK. Most countries follow a similar format, but there are some differences. In the USA , for example, PhD students complete reading assignments and examinations before beginning their research. You can find out more in our guides to PhD study around the world .

The second year of a PhD

Your second year will probably be when you do most of your core research. The process for this will vary depending on your field, but your main focus will be on gathering results from experiments, archival research, surveys or other means.

As your research develops, so will the thesis (or argument) you base upon it. You may even begin writing up chapters or other pieces that will eventually form part of your dissertation .

You’ll still be having regular meetings with your supervisor. They’ll check your progress, provide feedback on your ideas and probably read any drafts your produce.

The second year is also an important stage for your development as a scholar. You’ll be well versed in current research and have begun to collect some important data or develop insights of your own. But you won’t yet be faced with the demanding and time-intensive task of finalising your dissertation.

So, this part of your PhD is a perfect time to think about presenting your work at academic conferences , gaining teaching experience or perhaps even selecting some material for publication in an academic journal. You can read more about these kinds of activities below.

The third year of a PhD

The third year of a PhD is sometimes referred to as the writing up phase.

Traditionally, this is the final part of your doctorate, during which your main task will be pulling together your results and honing your thesis into a dissertation .

In reality, it’s not always as simple as that.

It’s not uncommon for final year PhD students to still be fine-tuning experiments, collecting results or chasing up a few extra sources. This is particularly likely if you spend part of your second year focussing on professional development.

In fact, some students actually take all or part of a fourth year to finalise their dissertation. Whether you are able to do this will depend on the terms of your enrolment – and perhaps your PhD funding .

Eventually though, you are going to be faced with writing up your thesis and submitting your dissertation.

Your supervisor will be very involved in this process. They’ll read through your final draft and let you know when they think your PhD is ready for submission.

All that’s left then is your final viva voce oral exam. This is a formal discussion and defence of your thesis involving at least one internal and external examiner. It’s normally the only assessment procedure for a PhD. Once you’ve passed, you’ve done it!

Doing a PhD – what's it actually like?

You can think of the ‘stages’ outlined above as the basic ‘roadmap’ for a PhD, but the actual ‘journey’ you’ll take as a research student involves a lot of other sights, a few optional destinations and at least one very important fellow passenger.

Carrying out research

Unsurprisingly, you’ll spend most of your time as a PhD researcher… researching your PhD. But this can involve a surprisingly wide range of activities.

The classic image of a student working away in the lab, or sitting with a pile of books in the library is true some of the time – particularly when you’re monitoring experiments or conducting your literature review.

Your PhD can take you much further afield though. You may find yourself visiting archives or facilities to examine their data or look at rare source materials. You could even have the opportunity to spend an extended period ‘in residence’ at a research centre or other institution beyond your university.

Research is also far from being a solitary activity. You’ll have regular discussions with your supervisor (see below) but you may also work with other students from time to time.

This is particularly likely if you’re part of a larger laboratory or workshop group studying the same broad area. But it’s also common to collaborate with students whose projects are more individual. You might work on shorter projects of joint interest, or be part of teams organising events and presentations.

Many universities also run regular internal presentation and discussion groups – a perfect way to get to know other PhD students in your department and offer feedback on each other’s work in progress.

Working with your supervisor

All PhD projects are completed with the guidance of at least one academic supervisor . They will be your main point of contact and support throughout the PhD.

Your supervisor will be an expert in your general area of research, but they won’t have researched on your exact topic before (if they had, your project wouldn’t be original enough for a PhD).

As such, it’s better to think of your supervisor as a mentor, rather than a teacher.

As a PhD student you’re now an independent and original scholar, pushing the boundaries of your field beyond what is currently known (and taught) about it. You’re doing all of this for the first time, of course. But your supervisor isn’t.

They’ll know what’s involved in managing an advanced research project over three years (or more). They’ll know how best to succeed, but they’ll also know what can go wrong and how to spot the warning signs before it does.

Perhaps most importantly, they’ll be someone with the time and expertise to listen to your ideas and help provide feedback and encouragement as you develop your thesis.

Exact supervision arrangements vary between universities and between projects:

• In Science and Technology projects it’s common for a supervisor to be the lead investigator on a wider research project, with responsibility for a laboratory or workshop that includes several PhD students and other researchers.
• In Arts and Humanities subjects, a supervisor’s research is more separate from their students’. They may supervise more than one PhD at a time, but each project is essentially separate.

It’s also becoming increasingly common for PhD students to have two (or more) supervisors. The first is usually responsible for guiding your academic research whilst the second is more concerned with the administration of your PhD – ensuring you complete any necessary training and stay on track with your project’s timetable.

However you’re supervised, you’ll have regular meetings to discuss work and check your progress. Your supervisor will also provide feedback on work during your PhD and will play an important role as you near completion: reading your final dissertation draft, helping you select an external examiner and (hopefully) taking you out for a celebratory drink afterwards!

Professional development, networking and communication

Traditionally, the PhD has been viewed as a training process, preparing students for careers in academic research.

As such, it often includes opportunities to pick up additional skills and experiences that are an important part of a scholarly CV. Academics don’t just do research after all. They also teach students, administrate departments – and supervise PhDs.

The modern PhD is also viewed as a more flexible qualification. Not all doctoral graduates end up working in higher education. Many follow alternative careers that are either related to their subject of specialism or draw upon the advanced research skills their PhD has developed.

PhD programmes have begun to reflect this. Many now emphasise transferrable skills or include specific training units designed to help students communicate and apply their research beyond the university.

What all of this means is that very few PhD experiences are just about researching and writing up a thesis.

The likelihood is that you’ll also do some (or all) of the following during your PhD:

The work is usually paid and is increasingly accompanied by formal training and evaluation.

Conference presentation

As a PhD student you’ll be at the cutting edge of your field, doing original research and producing new results. This means that your work will be interest to other scholars and that your results could be worth presenting at academic conferences .

Doing this is very worthwhile, whatever your career plans. You’ll develop transferrable skills in public speaking and presenting, gain feedback on your results and begin to be recognised as an expert in your area.

Conferences are also great places to network with other students and academics.

Publication

As well as presenting your research, you may also have the opportunity to publish work in academic journals, books, or other media. This can be a challenging process.

Your work will be judged according to the same high standards as any other scholar’s and will normally go through extensive peer review processes. But it’s also highly rewarding. Seeing your work ‘in print’ is an incredible validation of your PhD research and a definite boost to your academic CV.

Public engagement and communication

Academic work may be associated with the myth of the ‘ivory tower’ – an insular community of experts focussing on obscure topics of little interest outside the university. But this is far from the case. More and more emphasis is being placed on the ‘impact’ of research and its wider benefits to the public – with funding decisions being made accordingly.

Thankfully, there are plenty of opportunities to try your hand at public engagement as a PhD student. Universities are often involved in local events and initiatives to communicate the benefits of their research, ranging from workshops in local schools to public lectures and presentations.

Some PhD programmes include structured training in order to help students with activities such as the above. Your supervisor may also be able to help by identifying suitable conferences and public engagement opportunities, or by involving you in appropriate university events and public engagement initiatives.

These experiences will be an important part of your development as a researchers - and will enhance the value of your PhD regardless of your career plans.

What is a PhD for – and who should study one?

So, you know what a PhD actually is, what’s involved in completing one and what you might get up to whilst you do. That just leaves one final question: should you do a PhD?

Unfortunately, it’s not a question we can answer for you.

A PhD is difficult and uniquely challenging. It requires at least three years of hard work and dedication after you’ve already completed an undergraduate degree (and probably a Masters degree too).

You’ll need to support yourself during those years and, whilst you will be building up an impressive set of skills, you won’t be directly progressing in a career.

But a PhD is also immensely rewarding. It’s your chance to make a genuine contribution to the sum of human knowledge and produce work that other researchers can (and will) build on in future. However obscure your topic feels, there’s really no such thing as a useless PhD.

A PhD is also something to be incredibly proud of. A proportionately tiny number of people go on to do academic work at this level. Whatever you end up doing after your doctorate you’ll have an impressive qualification – and a title to match. What’s more, non-academic careers and professions are increasingly recognising the unique skills and experience a PhD brings.

Other PhDs - do degree titles matter?

The PhD is the oldest and most common form of higher research degree, but a few alternatives are available. Some, such as the DPhil are essentially identical to a PhD. Others, such as the Professional Doctorate or DBA are slightly different. You can find out more in our guide to types of PhD .

Is a PhD for me?

There’s more advice on the value of a PhD – and good reasons for studying one – elsewhere in this section. But the following are some quick tips if you’re just beginning to consider a PhD.

Speak to your lecturers / tutors

The best people to ask about PhD study are people who’ve earned one. Ask staff at your current or previous university about their experience of doctoral research – what they enjoyed, what they didn’t and what their tips might be.

If you’re considering a PhD for an academic career, ask about that too. Are job prospects good in your field? And what’s it really like to work at a university?

Speak to current PhD students

Want to know what it’s like studying a PhD right now? Or what it’s like doing research at a particular university? Ask someone who knows.

Current PhD students were just like you a year or two ago and most will be happy to answer questions.

If you can’t get in touch with any students ‘face to face’, pop over to the Postgraduate Forum – you’ll find plenty of students there who are happy to chat about postgraduate research.

Take a look at advertised projects and programmes

This may seem like a strange suggestion. After all, you’re only going to study one PhD, so what’s the point of reading about lots of others?

Well, looking at the details of different PhD projects is a great way to get a general sense of what PhD research is like. You’ll see what different PhDs tend to have in common and what kinds of unique opportunity might be available to you.

And, with thousands of PhDs in our database , you’re already in a great place to start.

What is a PhD?

• Types of Doctorates
• A Doctor of Philosophy (PhD) is the highest globally recognized postgraduate degree that higher education institutions can award.
• PhDs are awarded to candidates who undertake original and extensive research in a particular field of study.
• Full time PhD programmes typically last three to four years, whilst part time PhD programmes typically last six to seven years.
• A PhD can lead to an academia teaching role or a career in research. A PhD can also equip you with skills suitable for a wide range of jobs unrelated to your research topic or academia.

Definition of a PhD – A Doctor of Philosophy (commonly abbreviated to PhD , Ph.D or a DPhil ) is a university research degree awarded from across a broad range of academic disciplines; in most countries, it is a terminal degree, i.e. the highest academic degree possible.

PhDs differ from undergraduate and master’s degrees in that PhDs are entirely research-based rather than involving taught modules (although doctoral training centres (DTCs) offer programmes that start with a year of lecture-based teaching to help develop your research skills prior to starting your project).

In most English-speaking countries, those that complete a PhD use the title “Doctor” (typically abbreviated to Dr) in front of their names and are referred to as such within academic and/or research settings. Those that work in fields outside of academia may decide not to use the formal doctor title but use post-nominal letters (e.g. John Smith PhD); it’s unusual though for someone to use both the Doctor title and post-nominal letters in their name.

PhD vs Doctorate

A PhD and a professional doctorate are both research-based terminal degrees.

However, where a PhD focuses on original research mostly around theoretical concepts, a professional doctorate focuses on examining existing knowledge to solve real-life, practical problems.

While there is much crossover between the two, a PhD is generally better suited for an individual to wants to advance the knowledge and understanding in their field, and a professional doctorate degree is better suited to a working professional who wants to better be able to apply knowledge and understanding to their field.

What Are the Entry Requirements for a PhD?

To be accepted on to a PhD programme, students usually need to hold at least a high ( 2:1 and above ) undergraduate degree that is related to the field of research that they want to pursue. A PhD candidate may also be expected to hold a Master’s degree , however, this does not mean you must have one, as it is still possible to enrol into a PhD without a Master’s .

Self-funded courses may sometimes be more relaxed in relation to entry requirements . It may be possible to be accepted onto a self-funded PhD programme with lower grades, though these students typically demonstrate their suitability for the role through professional work experience.

Whilst a distance learning project is possible , most PhD candidates will carry out their research over at least three years based at their university, with regular contact with two academic supervisors (primary and secondary). This is particularly the case for lab-based projects, however, some PhD projects require spending time on-site away from university (e.g. at a specialist research lab or at a collaborating institution abroad).

How Long Does a PhD Take?

Typically, full-time PhDs last 3-4 years and part-time PhDs last 6-7 years. However, at the discretion of the university, the thesis writing-up period can be extended by up to four years.

Although most doctoral programmes start in September or October, they are generally much more flexible than taught-courses and can start at any time of the year.

How Much Does a PhD Cost?

Tuition fees for UK and EU students vary between £3,000 and £6,000 per year, with the average tuition fee of £4,712 per year for 2023/24 programmes.

Tuition fees increase considerably for international students, varying between £16,000 to £25,000 per year, with an average tuition fee of £19,600 per year .

Nonetheless, most students will secure PhD funding in the form of studentships, scholarships and bursaries to help pay for these fees. These funding opportunities can either be partial, which cover tuition fees only, or full, which cover both tuition fees and living expenses.

UK national students can also apply for Doctoral Loans from Student Finance England if they are unable to secure funding.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Does a PhD Involve?

To be awarded a PhD, a doctoral student is required to produce a substantial body of work that adds new knowledge to their chosen field.

A PhD programme will typically involve four key stages:

Stage 1: Literature Review

The first year of a PhD involves attending regular meetings with your supervisors and carrying out a search on previously published work in your subject area. This search will be used to produce a literature review which should set the context of the project by explaining the foundation of what is currently known within the field of research, what recent developments have occurred, and where the gaps in knowledge are. In most cases, this will be an extension of your research proposal should you have produced one as part of your application. The literature review should conclude by outlining the overarching aims and objectives of the research project. This stage of setting achievable goals which are original and contribute to the field of research is an essential first step in a successful PhD.

The supervisor is the main point of contact through the duration of a PhD – but remember: they are there to mentor, not to teach, or do it for you . It will be your responsibility to plan, execute and monitor your own work as well as to identify gaps in your own knowledge and address them.

Stage 2: Research

The second year (and prehapse some of your third year) is when you work on your research. Having identified novel research questions from your review of the literature, this is where you collect your data to help answer these questions. How you do this will depend on the nature of your doctoral research: for example, you may design and run experiments in a lab alongside other PhD students or visit excavation sites in remote regions of the world. You should check in regularly with your supervisors to update them and run any ideas or issues past them.

Have the structure and chapters of your thesis in mind as you develop and tackle your research questions. Working with a view of publishing your work will be very valuable later on.

Stage 3: Write up of Thesis

The next key stage of a PhD is writing a doctoral thesis , which typically takes from anywhere between three months to one year. A thesis is a substantial body of work that describes the work and outcomes of the research over the previous two to three years. It should tell a detailed story of the PhD project – focusing on:

• The motivations for the research questions identified from the literature review.
• The methodologies used, results obtained, and a comprehensive analysis and discussion of the findings.
• A detailed discussion of the key findings with an emphasis on the original contributions made to your field of research and how this has been impactful.

There is no universal rule for the length of a PhD thesis, but general guidelines set the word count between 80,000 to 100,000 words.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available.

Stage 4: Attending the Viva

A viva voce , most commonly referred to as just a ‘ viva ‘, is an interview-style examination where the PhD student is required to engage in a critical appraisal of their work and defend their thesis against at least two examiners. The examiners will ask questions to check the PhD student has an in-depth understanding of the ideas and theories proposed in their thesis, and whether they have developed the research skills that would be expected of them.

The viva is one of the final steps in achieving a PhD, and typically lasts at least two hours, but this duration can vary depending on the examiners, the university and the PhD project itself.

Once you have done the viva – you’re on the home stretch. You will typically be asked to make some amendments to your thesis based on the examiner’s feedback. You are then ready to submit your final thesis for either:

• PhD – If you pass the requirements you will be awarded a PhD degree (most common outcome),
• MPhil – If you failed to meet requirements for a PhD, you may be downgraded to an MPhil degree (uncommon outcome),
• Fail – No award is given, typically for cases of plagiarism (extremely uncommon outcome).

What Is It Like to Undertake a PhD?

We’re often asked what it is like to undertake a PhD study. Unfortunately, this isn’t a simple answer to this question as every research project is different.

To help give insight into the life of a PhD student, we’ve interviewed PhD students at various stages of their programmes and put together a series of PhD Student Interviews . Check out the link to find out what a PhD is like and what advice they have to offer you.

What Are the Benefits of A PhD?

A PhD is the highest globally recognised postgraduate degree that higher education institutions can award. The degree, which is awarded to candidates who demonstrate original and independent research in a particular field of study, is not only invaluable in itself, but sets you up with invaluable skills and traits.

Career Opportunities

First, a PhD prepares you for a career in academia if you wish to continue in this area. This takes form as a career in the Higher Education sector, typically as a lecturer working their way to becoming a professor leading research on the subject you’ve studied and trained in.

Second, a PhD also enables the opportunity for landing a job in a research & development role outside of the academic environment. Examples of this include laboratory work for a private or third sector company, a governmental role and research for commercial and industrial applications.

Transferable Skills

Finally, in possessing a PhD degree, you can show to employers that you have vital skills that make you an asset to any company. Three examples of the transferable skills that you gain through a PhD are effective communication, time management, and report writing.

• Communication – presenting your work in written and oral forms using journal papers and podium presentations, shows your ability to share complex ideas effectively and to those with less background knowledge than you. Communication is key in the professional environment, regardless of the job.
• Time management – The ability to prioritise and organise tasks is a tremendous asset in the professional industry. A PhD holder can use their qualification to demonstrate that they are able to manage their time, arrange and follow a plan, and stick to deadlines.
• Report writing – Condensing three years of work into a thesis demonstrates your ability to filter through massive amounts of information, identify the key points, and get these points across to the reader. The ability to ‘cut out the waffle’ or ‘get to the point’ is a huge asset in the professional industry.

Aside from the above, you also get to refer to yourself as a Doctor and add fancy initials after your name!

What Can I Do After a PhD?

One of the most desirable postdoctoral fields is working within independent Research and Development (R&D) labs and new emerging companies. Both industries, especially R&D labs, have dedicated groups of PhD graduates who lead research activities, design new products and take part in crucial strategic meetings. Not only is this a stimulating line of work, but the average salaries in R&D labs and emerging start-ups are lucrative. In comparison, an undergraduate with five years of experience within their given field will, on average, likely earn less than a new PhD graduate taking on a R&D position.

It’s a common misunderstanding that PhDs only opens the door for an academic career such as university lecturers and training providers. Although obtaining a PhD opens these doors, the opportunities extend far beyond educational roles. In fact, recent data from the UK’s Higher Education Statistics Agency (HESA) indicates only 23% of PhD graduates take a position in educational roles . This low percentage is primarily because PhD graduates have a wide range of skills that make them suitable for a broad spectrum of roles. This is being seen first hand by the increasing number of PhD graduates who are entering alternative roles such as research, writing, law and investment banking.

How Do I Find a PhD?

We appreciate that finding a PhD programme to undertake can be a relatively daunting process. According to Higher Education Student Statistics , over 22,000 PhDs were awarded in 2016/17 within the United Kingdom alone. Clearly there are a huge number of PhD programmes available. This can sometimes be confusing for prospective doctorates, particularly when different programmes are advertised in different places. Often, it is difficult to know where to look or where to even start. We’ve put together a list of useful sources to find the latest PhD programmes:

• A great place to start is with our comprehensive and up-to-date database of available PhD positions .
• Assuming you are still at university, speak to an existing PhD supervisor within your department.
• Attend as many postgraduate open days as you can. Whilst there, speak to current PhD students and career advisors to get an awareness of what PhDs are on offer.
• Visit the postgraduate section of university websites and the PhD Research Council section of the UKRI website.

What is a PhD Degree? [2024 Guide]

As you’re taking a look at potential grad school programs, you might be asking yourself, “What is a PhD degree?”

Understanding what a PhD is and what’s involved in earning one can help you decide whether to enroll in this type of doctoral program. You might decide that a PhD is a strategic step for you to take to further your career.

Editorial Listing ShortCode:

If you choose to pursue a PhD, you’ll be glad to know that you can also earn this type of degree online through an accredited university.

What Is a PhD Degree?

After earning a bachelors degree and a masters degree, you may be considering taking your education even further.

The next step for you might be a Doctor of Philosophy degree, better known as a PhD. As a terminal degree, a PhD can set you apart as an expert in your field. Earning a doctoral degree is not a small undertaking. The process includes multiple steps and can last for several years.

Components of a Ph.D. degree program often include:

• Advanced courses in your chosen field
• Classes in research methods, data analysis, and scholarly writing
• Examination of current literature and studies related to your field
• Oral or written comprehensive exams
• Original research project—includes writing and defending a major paper about your research

The dissertation, sometimes known as a thesis, is usually the part of a PhD program that takes the longest. During the dissertation process, you’ll work under the supervision of a faculty advisor, often someone whose research interests correlate with yours. You’ll design a research project, carry it out, and write about your findings. This project is meant to contribute new ideas to your field.

A PhD is particularly suitable for students who love school settings and want to pursue academic careers. For instance, professors often have PhDs. It’s also common for scientists and other researchers to hold this type of degree. Outside of  academia, a PhD could set you apart as a knowledgeable leader in your field.

Benefits of a PhD Degree

Getting your PhD can be an incredible personal goal worth achieving. Plus, a degree at this level can offer many professional benefits, such as:

• Career advancement . As a person with a PhD, you may be considered an expert in your field. That could help qualify you for a variety of top roles within your line of work.
• Higher earnings . A job promotion or a new employer might offer you a higher salary.
• Networking . You can meet new people and build professional connections as you work toward a PhD.
• Preparation for becoming a professor . Universities typically prefer to hire faculty members who hold PhDs in their area of expertise.
• Research opportunities . Before you can earn your PhD, it’s necessary to complete an original research project called a dissertation. After completing your degree, you may have additional opportunities to contribute research to your field.

If you’re willing to put in the work, then getting your PhD could be worth the effort.

How to Know If a PhD Is Right for Me

Before you sign up for a PhD program, it’s helpful to carefully weigh the decision and make sure it’s the right choice for you. You might ask yourself the following questions:

• Am I willing to commit years to the process ? PhDs take at least 3 years, and most take longer than that.
• Do I want to carry out original research ? This is a research-focused degree, and the purpose is to contribute new ideas or theories to your field.
• Does an academic career interest me ? Many people get PhDs because they want to work in higher education as teachers or researchers. Those who plan to remain as practitioners often consider professional doctorates instead.

It can also be helpful to speak with faculty members and current students to get a feel for what you can expect from PhD studies.

Applying for a Ph.D: Education Requirements

It’s necessary to put in years of study before you can apply for a PhD program. Most students need to hold at least two degrees already. But, in some cases, one may be sufficient.

• Bachelor’s degree . All graduate programs require students to have earned a four-year undergraduate degree before enrolling in advanced studies. Most PhD programs don’t specify that your bachelors degree must be in the same field as your hoped-for doctoral studies, but it can help you move through a graduate-level program with more ease.
• Master’s degree . Colleges often expect students to have earned a master’s degree before applying for PhD studies, but some programs do allow students straight out of bachelor’s degree programs. Doing a master’s degree first can provide strong preparation for the advanced coursework, research, and writing that are required in doctoral programs.

It is often required that the degrees you have be from accredited colleges. It may also be necessary to meet a minimum GPA requirement, such as a score of 3.0 or higher. Some colleges prefer PhD applicants who have graduated from previous programs with honors.

Doctor of Philosophy: Admissions Requirements

Doctoral programs can be quite selective about whom they admit because they’re looking for capable students who can keep up with the demands of the program and contribute valuable new research to the field.

In addition to meeting the education requirements, you’ll also be required to turn in records that demonstrate your academic potential. Here are some common admissions requirements:

• College transcripts and professional resume
• Letters of recommendation from people who know you academically or professionally
• Statement about relevant background, research interests, or professional goals
• Proposal that presents the original research project you’d be interested in doing
• Scores from the GRE or GMAT (not always required)

You might also connect with the department’s faculty members and find someone who would be willing to serve as your academic supervisor for your dissertation. It’s beneficial for this person’s research interests to align with your own.

Some schools have you do this before admission, and others connect admitted students to supervisors later in the enrollment process.

What Does PhD Stand For?

PhD stands for “Doctor of Philosophy.” It doesn’t mean that you’ve studied philosophy at the highest levels. Rather, the word “philosophy” in the name refers back to ancient Greek. It implies that you are someone who loves and seeks wisdom and knowledge.

You can get a PhD in many different subject areas—such as a Doctor of Philosophy in Mathematics or a Doctor of Philosophy in Psychology. PhD students explore their chosen field of study in great depth. They also learn how to conduct original research, and they undertake major research projects. By graduation, they are considered experts in their fields.

What Do You Learn in a Doctoral Degree?

In a PhD program, you’ll learn about your chosen area of study, such as biology or sociology. You will also study a niche area within that field in great depth.

Research is a significant topic in any PhD program. Your courses might include topics on:

• Advanced statistics
• Dissertation preparation
• Literature review
• Quantitative and qualitative methods
• Research methodology

These research-focused classes may be tailored to your particular area of study, such as research methodology in the social sciences or advanced statistics in criminal justice research.

What Can You Do with a PhD Degree?

Many people earn PhD degrees because they want to teach at the college level. This degree is often required for tenured faculty positions at universities.

The Bureau of Labor Statistics states that most postsecondary teachers earn between $46,690 and $172,130 each year. Research scientists often hold PhDs as well. Examples include medical scientists, biochemists, and physicists.

Additionally, there are some career paths that require a doctorate for licensure. For instance, clinical and counseling psychologists usually need to receive training at the doctoral level before they can practice independently.

Do You Need a Masters to Get a PhD?

Whether you’ll need a masters before you can begin the PhD process will depend on the program you choose.

Many PhD programs require a master’s degree as an admissions requirement. Completing a master’s program can provide a strong research and writing foundation that can help you during this advanced program. Other programs, though, let students enroll with only a bachelors degree.

There might be additional classes required to prepare you for working at the graduate level, so it may take a bit longer to complete your studies. For more information on whether you need a master’s to get a PhD , you can consult the admissions requirements of each program you’re considering.

Can You Get a PhD Online?

There are many online PhD programs available for aspiring students looking for flexibility. Some PhD programs are offered entirely online. You can take all of your classes online, and you can also receive guidance from your faculty advisor and defend your dissertation from afar.

Other programs are mostly online but require some in-person experiences. You might be asked to come to campus for a week or two of intensive study. Also, you may be asked to show up in person for your dissertation defense. Either way, online PhD studies are often more accessible for working professionals than fully on-campus programs.

How Long Does It Take to Get a PhD?

Students often spend 3 to 5 years completing a PhD program. Online programs sometimes include features like year-round classes and short course terms that encourage quick completion.

The shortest PhD programs typically do not involve writing a dissertation. There may be a different final assignment, such as a capstone project, instead. You might be able to finish one of those programs in about 3 years. Not all students finish within 5 years. Some spend around a decade on this massive undertaking. Some PhD programs set an upper limit for completion, such as 7 or 8 years.

Is a PhD a Doctor?

People with PhDs are considered experts in their fields, and the degree includes “Doctor” in its name. For that reason, PhD holders often use the title “Doctor.” A college professor, for example, might go by Dr. Smith.

Even still, there’s a difference between MD vs. PhD. A person who holds a PhD is not a medical doctor. Medical doctors earn a Doctor of Medicine (MD) degree before becoming licensed to practice medicine. In most contexts, though, people refer to professionals with PhDs as “doctors.”

What Jobs Can You Get with a PhD?

People with doctorate degrees work in both academia and professional practice. Being a college professor is quite popular among people who hold PhDs. The Bureau of Labor Statistics says that a PhD can also be helpful for obtaining jobs in higher education administration, particularly as a dean or a provost.

PhD graduates may work in research as well. Research jobs are available with colleges, government agencies, and private institutions. Researchers are needed in many different fields, including biology, mathematics, computer science, and economics. PhDs also help people rise to the top in their industries, perhaps as chief executives.

How Much Does a PhD Cost?

Some graduate schools charge just $300 to $400 per credit hour. Others may charge $2,000 per credit hour or more.

Per-credit-hour rates between $600 and $1,000 are quite common. It’s helpful to keep in mind that state universities often charge less for in-state residents than nonresidents. Your total number of credit hours may depend on how many years you spend working on your dissertation.

Some universities offer tuition-free PhD programs for qualifying participants. The students may even receive a stipend in exchange for research or teaching assistance. This arrangement is more common for on-campus programs than online ones.

What’s the Difference Between a Doctorate vs. PhD Degrees?

Is a PhD a doctorate degree ? For your terminal degree, you may have the choice between a PhD degree and a professional doctorate. While they are both doctoral degrees, they do have some differences.

Professional doctorates are sometimes a year or two quicker than PhDs, but that’s not always the case.

Is a PhD Worth It?

Yes, a PhD is worth it for many students. For one thing, holding a PhD could be the key to fulfilling your professional dreams.

If you want to be a professor, for instance, there’s a good chance that you’ll be required to have this advanced degree. Even if that’s not your ultimate goal, a PhD could be beneficial. The more education you have, the more your job security usually increases.

According to the Bureau of Labor Statistics, there’s an inverse relationship between education and unemployment. As education increases, unemployment rates decrease.

Getting Your PhD Degree Online

An exciting future as an expert in your field may await. You can earn a PhD to increase your knowledge, prove your capability, and contribute new ideas to your area of study. Getting this degree is an impressive accomplishment, and it may open new doors for your career. For convenience and accessibility, you might take a look at online PhD studies.

Many accredited colleges offer robust online PhD programs. You’ll get to take advanced courses and work with respected professors. An online program can also offer opportunities for completing a thesis or a doctoral project. You could graduate prepared to make a difference in your field.

More than 54,000 students earned doctoral degrees in 2016, the latest year for which figures are available, a 30 percent increase since 2000, according to the  National Science Foundation . A Ph.D., also called a doctorate, is a "Doctor of Philosophy" degree, which is a misleading moniker because most Ph.D. holders are not philosophers. The term for this increasingly popular degree derives from the original meaning of the word "philosophy," which comes from the ancient Greek word  philosophia , meaning "love of wisdom."

What Is a Ph.D.?

In that sense, the term "Ph.D." is accurate, because the degree has historically been a license to teach, but it also signifies that the holder is an "authority, in full command of (a given) subject right up to the boundaries of current knowledge, and able to extend them," says  FindAPhD , an online Ph.D. database. Earning a Ph.D. requires a hefty financial and time commitment— $35,000 to $60,000  and two to eight years—as well as research, creating a thesis or dissertation, and possibly some teaching duties.

Deciding to pursue a Ph.D. can represent a major life choice. Doctoral candidates require additional schooling after completing a master's program to earn their Ph.D.: They must complete additional coursework, pass comprehensive exams , and complete an independent dissertation in their field. Once completed, though, a doctoral degree—often called a "terminal degree"—can open doors for the Ph.D.holder, especially in academia but also in business.

Core Courses and Electives

To obtain a Ph.D., you need to take a group of core courses as well as electives, totaling about 60 to 62 "hours," which are roughly the equivalent of units at the bachelor's degree level. For example, Washington State University offers a  Ph.D. in crop science . Core courses, which make up about 18 hours, include such subjects as introduction to population genetics, plant transmission genetics, and plant breeding.

Additionally, the student must make up the remaining required hours through electives. The  Harvard T.H. Chan School of Public Health  offers a doctoral degree in Biological Sciences in Public Health. After core courses such as laboratory rotations, biological sciences seminars, and core principles of biostatistics and epidemiology, the Ph.D. candidate is required to take electives in related fields such as advanced respiratory physiology, advanced respiratory physiology, and ecological and epidemiological control of parasitic diseases. Degree-granting institutions across the board want to ensure that those who earn Ph.D.s have broad knowledge in their chosen field.

Thesis or Dissertation and Research

A Ph.D. also requires students to complete a large scholarly project known as a  dissertation , a research report—usually 60-plus pages—which signifies that they are able to make significant independent contributions to their chosen field of study. Students take on the project, also known as a  doctoral thesis , after completing the core and elective coursework and passing a  comprehensive examination . Through the dissertation, the student is expected to make a new and creative contribution to a field of study and to demonstrate her expertise.

According to the Association of American Medical Colleges, for example, a strong medical dissertation relies heavily on the creation of a specific hypothesis that can be either disproved or supported by data collected through independent student research. Further, it must also contain several key elements starting with an introduction to the problem statement, conceptual framework, and research question as well as references to literature already published on the topic. Students must show that the  dissertation  is relevant, provides new insight into the chosen field, and is a topic that they can research independently.

Financial Aid and Teaching

There are several ways to pay for a doctoral degree: scholarships, grants, fellowships, and government loans, as well as teaching.  GoGrad , a graduate school information website, provides such examples as the:

• Science, Mathematics, and Research for Transformation (SMART) Scholarship for Service Program, which provides full tuition and an annual stipend of $25,000 to $38,000.
• National Defense Science and Engineering Graduate Fellowship, a three-year graduate fellowship that is designed to support doctoral students across 15 engineering disciplines
• National Science Foundation Graduate Research Fellowship Program, a three-year program that provides an annual stipend of $34,000 and a $12,000 cost-of-education allowance for tuition and fees

As it does for bachelor's and master's degrees, the federal government also offers several  loan programs  to help students finance their Ph.D. studies. You generally apply for these loans by filling out the free application for federal student aid ( FAFSA ). Students planning to go into teaching after obtaining their doctoral degrees often also supplement their income by teaching undergraduate classes at the schools where they are studying. The University of California, Riverside, for example, offers a "teaching award"—essentially a stipend applied toward tuition costs—for Ph.D. candidates in English who teach undergraduate, beginning-level, English courses

Jobs and Opportunities for Ph.D. Holders

Education accounts for a large percentage doctoral awards, with elementary education, curriculum and instruction, educational leadership and administration, special education, and counselor education/ school counseling topping the list. Most universities in the United States require a Ph.D. for candidates who seek teaching positions, regardless of the department.

Many Ph.D. candidates seek the degree, however, to boost their current salaries. For example, a health, sports, and fitness educator at a community college would realize a bump in annual pay for obtaining a Ph.D. The same holds for educational administrators. Most such positions require only a master's degree, but obtaining a Ph.D. generally leads to an annual stipend that school districts add to the annual salary. That same health and fitness instructor at a community college could also move on from a teaching position and become a dean at a community college—a position that requires a Ph.D.—boosting his pay to  $120,000 to $160,000  a year or more.

So, the opportunities for a doctoral degree holder are wide and varied, but the cost and commitment required are significant. Most experts say you should know your future career plans before you make the commitment. If you know what you want to get out of the degree, then the years of required study and sleepless nights may well be worth the investment.

Doctorate Degree: What Is a Doctorate or Doctoral Degree?

Maybe you recently completed a master’s degree program and want to take your education — and your earning potential — to a higher level. Maybe you’re a high school senior who’s planning on a future career that requires you to hold a doctorate degree, such as becoming a psychiatrist or surgeon. Or, maybe you’re currently working toward your master’s or bachelor’s degree, and you want to know more about whether continuing your education is worthwhile.

Whichever stage you’ve reached in your academic or professional career, this guide will help answer the crucial question: What is a doctorate or doctoral degree, and is earning one the right choice for you? It covers all of your FAQs about doctorate degree programs, including answers to questions like:

• Is a doctorate degree the same as a PhD?
• Are there different kinds of doctorate degrees?
• What are the stages of earning your doctoral degree?
• How much does a doctorate degree increase your earning potential?

If you’ve ever wondered about the answers to any of these questions, read on to discover the basics about doctoral degrees and PhD programs.

What is a Doctorate Degree?

A doctorate degree — also called a doctoral degree — is the most rigorous and advanced type of degree that a student can earn in any field of study. Regardless of which academic area is being studied, successful completion of a doctorate program demands years of intensive research — and the ability to contribute meaningful new data, solutions, theories, or analyses to the field. Professionals who obtain doctorate degrees have extensive experience and are regarded as authorities in their specialty areas. They are frequently sought after for consulting, management, or research positions in a variety of industries. By earning a doctorate degree, you can greatly enhance the power of your resume — and with it, your earning potential.

For more details on that subject, skip ahead to the section about average salaries for students who obtain doctorate degrees. Or, continue reading for the answer to one of our most frequently asked questions: is a doctorate degree the same as a PhD?

Doctorate vs. PhD Degrees

What’s the difference between a doctoral degree and a PhD? Put simply, a PhD or Doctor of Philosophy is a doctorate degree — but only one of several varieties. Read on to learn more about the major categories of doctoral degrees and some important ways in which they differ from one another.

Types of Doctoral Degrees

You already know that there are different types of graduate and undergraduate degrees, such as a Bachelor of Arts (BA) versus a Bachelor of Science (BS), or a Master of Business Administration (MBA) versus a Master of Public Administration (MPA). A similar idea applies to doctoral degrees, which are also divided into several categories. Namely, there are two different types of doctorate degrees that students should be aware of:

• Professional doctorate degrees
• Doctor of Philosophy degrees

The sections below will compare and contrast the important differences between these two-degree types.

Professional Doctorate Degrees

Professional doctoral degrees are also referred to as terminal or applied doctoral degrees. In contrast to PhD degrees, which the following section discusses in further detail, professional degrees place more of an emphasis on real-world problem-solving and the practical application of knowledge, as opposed to exploring new advancements or ideas in research and analysis.

Professional degrees are essential for those who wish to pursue certain career paths. For example, in addition to meeting other academic and professional criteria like passing the bar exam, you will need to obtain a Juris Doctor (JD) degree if your goal is to become an attorney. In addition to the JD for lawyers, here are four additional examples of professional or applied doctorate degrees:

• Doctor of Business Administration (DBA)
• Doctor of Pharmacy (PharmD)
• Doctor of Social Work (DSW)

Doctor of Philosophy (PhD) Degrees

This category includes the Doctor of Philosophy or PhD degree, which is applicable to various fields, such as holding a PhD in economics or psychology. However, it also includes various degrees whose titles and abbreviations may sound less familiar. For instance, did you know that a Doctor of Arts is actually a type of PhD, despite being called a DA? Here are four other examples of PhD degrees:

• Doctor of Public Health (DPH)
• Doctor in Organizational Innovation (EdD)
• Doctor of Theology (ThD)
• Doctor of Psychology (PsyD)

In contrast to a professional degree, such as a JD or DPH degree, a PhD is intensely research-oriented with a strong focus on presenting new knowledge or theories via the student’s dissertation. This is also the reason why PhD programs which have nothing to do with “philosophy” in the conventional sense are described using this term.

Steps To Obtain a Doctorate

Depending on factors like the format and pace of the program, it may require anywhere from three to eight years to obtain a doctorate degree, as the section below discusses in further detail. So what will you actually be doing as a student throughout that time?

To make your academic journey manageable and help ensure you remain focused on your goals, it’s important to have a clear road map to success. When comparing programs, it’s helpful to have an understanding of the four basic stages to earning your doctorate degree:

• Complete undergraduate and graduate degree programs to gain the prerequisite knowledge, training, skills, and qualifications you will need to enter your chosen doctoral program.
• Research and compare different options in detail, then apply to a doctorate program that’s aligned with your professional goals.
• Complete all of your coursework requirements.
• Complete an original dissertation on your chosen topic of research.

Read on to learn more about these key steps to earning a doctorate degree — and what will be required of you at each checkpoint. Or, if you’re ready to apply now, get in touch with our friendly team of enrollment counselors to learn more about the coursework and criteria for your program.

Step 1: Complete Your Undergraduate and Master’s Degree

Doctorate programs, which are growing more sought-after by students and employers alike, have rigorous and competitive application requirements. In addition to meeting other criteria which vary by institution and major, students will also generally need to possess a graduate or undergraduate degree, such as a bachelor’s degree, from an accredited college or university.

If you’re at the beginning of your academic journey and are applying to undergraduate programs, you should strongly consider selecting a program that is directly relevant to the master’s and/or doctorate program you intend to eventually enroll in — for example, mapping out a career in healthcare that begins with your Bachelor of Science in Nursing (BSN) and culminates with a doctorate, like your Doctor of Clinical Psychology (PsyD). However, it’s also possible to change careers if you’ve already completed your undergraduate degree.

With online classes and accelerated coursework, plus the option to transfer credits, National University provides the framework for you to launch or advance a rewarding career — no matter which stage of your journey you’ve reached. Explore our accredited master’s degree programs and bachelor’s degree programs for graduate and undergraduate students.

Step 2: Apply to Doctorate Programs

A doctorate program is a major investment in terms of the time, effort, and dedication required to reach your goals. It’s important to select a program that is not only reputable and accredited, but also, one that provides the support and flexibility you need in terms of scholarships and financial aid options ; is designed to help you complete your degree at an accelerated pace; features resources for U.S. military service members and Veterans, which you can learn more about here; and offers the option to complete portions of your doctorate coursework online.

National University offers three WASC-accredited doctoral programs in the fields of healthcare, psychology, and education, which you can read more about below. For additional information, contact our admissions office online or explore the following program pages.

• Doctor of Clinical Psychology Program (PsyD) — Students in our PsyD program complete a total of 180 program units covering coursework like Group Dynamics, Informed Treatment Planning, and Psychopharmacology. The PsyD program at National University is comprised of Ethnographic Placement, Beginning Practicum, Advanced Practicum, and Predoctoral Internship components culminating in a dissertation, and is designed to prepare students for roles as consultants, clinicians, evaluators, program administrators, and more.
• Doctor of Nurse Anesthesia Practice (DNAP) — The Doctor of Nurse Anesthesia Practice, or DNAP degree, is a fast-paced, three-year hybrid program that integrates online coursework with a 15-month didactic residency at NU’s Fresno campus. The DNAP degree program at National University prepares students for challenging roles in anesthesia care delivery via coursework like Anesthesia Pharmacology, Principles of Anesthesia, and Anesthesia Physiology, along with clinical rotations and a capstone project.
• Ed.D. in Organizational Innovation — Organizational innovation is an exciting academic field that looks at how to design and implement visionary solutions to a variety of challenges facing businesses, government entities, and other organizations. Coursework includes Innovation Theories and Application, Knowledge Management for Innovation, and Emerging Issues and Trends, concluding with a culminating project.

Step 3: Complete Program Coursework

In a doctoral degree program, students will typically complete a blend of core or required courses, seminars, practicums, labs, and electives, ultimately culminating in a dissertation or capstone project. Of course, as with any bachelor’s or master’s degree program, the specific nature and focus of your coursework is dependent on your area of study. For example, students in the Ed.D. program at National University complete mandatory courses in innovation theory and methods of inquiry, whereas students in our PsyD program are required to complete courses in subjects such as psychopathology, clinical theory, and multicultural awareness.

Whether it consists primarily of online or in-person study, you can expect your doctorate coursework to be rigorous. By this stage of your academic career, you’ll have completed your basic education and training and moved onto more challenging and scholarly areas of research, tackling complex real-world problems and presenting innovative, potentially even experimental solutions.

Step 4: Complete Your Dissertation

Most doctorate programs culminate in a major research project known as a dissertation, in which the student contributes to the scholarly body of work in their field by presenting their own original theories, research, or data analysis, or by building meaningfully upon the work of previous scholars and researchers. A dissertation usually takes the form of a written paper ranging anywhere in length from 100 to 300 pages, depending on the volume of data and complexity of the subject matter.

How Long Does it Take to Earn a Doctorate?

The time it takes to finish a doctorate program and earn your degree varies. However, most doctorate programs require anywhere from three to eight years to complete. The exact length of time depends on factors like the structure of your degree program; whether or not you decide to work and/or take time off between any of your courses; whether you attend your program on a full-time or part-time basis; the amount of time it takes you to finish researching, writing, and editing your dissertation; and, of course, which degree you’re pursuing.

At National University, our flexibly scheduled yet aggressively paced programs enable students to complete their education sooner — and advance along their chosen career paths faster. For example, our PsyD program may be completed in five years, while our Ed.D. and DNAP programs may be completed in as little as just three years, including options to complete portions of the program online while also integrating hands-on experience like the residency component of our accredited DNAP degree.

Demand for Doctoral Degrees

The demand for doctoral degrees continues to grow as industries seek highly specialized knowledge and advanced research skills. According to the U.S. Bureau of Labor Statistics (BLS), employment in doctoral and professional-level occupations is projected to grow by about 13% from 2016 to 2026, which is faster than the average growth rate for all occupations​. This increasing demand is particularly evident in fields such as healthcare, education, and technology, where the expertise and innovation brought by doctoral graduates are highly valued.

Salary Expectations for a Doctorate Degree

Pursuing a doctorate degree will expose you to new challenges and place you on the cutting edge of exciting new research in your field — and from a financial perspective, your degree will also help you to qualify for higher paid, more specialized positions. A doctorate degree or other advanced degree can also help you stand out favorably from other job applicants. So just how much can you expect to earn with a doctoral degree, depending on your chosen field and career?

According to data from the U.S. Bureau of Labor Statistics (BLS), holding a doctoral degree is correlated with increased earnings, as you can see in the following table . For example, the BLS reports that holders of doctorate degrees earned median weekly pay of approximately $1,900, compared to that of master’s degree holders (about $1,570) or the holders of bachelor’s and associate’s degrees (about $1,330 and $960, respectively). While pursuing a doctorate degree requires an investment in your education, it also offers a worthwhile return in the form of enhanced lifelong earning power — especially if you are able to qualify for scholarships and/or financial aid.

Frequently asked questions

What is a phd.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

Frequently asked questions: Graduate school

In the US, most graduate school applications require you to include:

• Transcripts from previous educational institutions
• Standardized test scores (such as the GRE or MCAT)
• A graduate resume
• 2–3 letters of recommendation
• A statement of purpose

Some programs may ask you to write a personal statement in addition to, or instead of, a statement of purpose. You may also be asked to an interview .

Always carefully read the application instructions for the specific program you’re applying to.

Most medical school programs interview candidates, as do many (though not all) leading law and business schools.

In research programs, it depends—PhDs in business usually do, while those in economics normally do not, for example.

Some schools interview everyone, while others only interview their top candidates. Look at the websites of the schools you’re applying to for more information on whether they conduct interviews.

In addition to thinking about your answers for the most commonly asked grad school interview questions , you should reach out to former and current students to ask their advice on preparing and what sort of questions will be asked.

Look back through your resume and come up with anecdotes that you could use for common questions, particularly those that ask about obstacles that you overcame. If you’re applying for a research program, ensure that you can talk about the previous research experience you’ve had.

You should also read as much research in your field as possible. Research the faculty at the schools you’re applying to and read some of their papers. Come up with a few questions that you could ask them.

Graduate schools often ask questions about why you are interested in this particular program and what you will contribute.

Try to stay away from cliche answers like “this is a good program” or “I got good grades in undergrad” and focus instead on the unique strengths of the program or what you will bring to the table. Understand what the program is looking for and come up with anecdotes that demonstrate why you are a good fit for them.

Different types of programs may also focus on different questions:

• Research programs will often ask what topics you’d like to research and who you would like to work with, as well as specific questions about your research background.
• Medical schools are interested in your personal motivation, qualities such as integrity and empathy, and how you’d respond to common ethical dilemmas.
• Business schools will focus on your past work experience and future career prospects, and may be particularly interested in any experience you have managing or working with others.

Some students apply to graduate school straight from undergrad, but it’s also common to go back to school later in life. The ideal time to do so depends on various financial, personal, and career considerations . Graduate school is a big commitment, so you should apply at a time when you can devote your full attention to it.

Your career path may also determine when you should apply. In some career fields, you can easily progress without a graduate degree, while in others—such as medicine, business, and law—it’s virtually impossible to move up the career ladder without a specific graduate degree.

Most graduate school applications for American graduate programs are due in December or January for a September start.

Some types of programs, especially law school, are rolling applications, meaning that the earlier you apply, the earlier you’ll hear back. In this case, you should aim to apply as early as possible to maximize your chances.

Medical school follows a completely separate timeline with much earlier deadlines. If you’re applying for medical school, you should speak to advisors at your university for more information.

A good starting point to aim for is about 18 months before you would start the program, or 6–9 months before the applications are due.

In the first few months of the process, research programs and study for any standardized exams you might need.

You can then begin writing your personal statements and statements of purpose , as well as contacting people to write your letters of recommendation . Ensure that you give recommenders plenty of time to complete their letters (ideally around 2–4 months).

In the US, the graduate school application process is similar whether you’re applying for a master’s or a PhD . Both require letters of recommendation , a statement of purpose or personal statement , a resume or CV , and transcripts. Programs in the US and Canada usually also require a certain type of standardized test—often the GRE.

Outside the US, PhD programs usually also require applicants to write a research proposal , because students are expected to begin dissertation research in the first year of their PhD.

A master’s degree usually has a higher upfront cost, but it also allows you to start earning a higher salary more quickly. The exact cost depends on the country and the school: private universities usually cost more than public ones, and European degrees usually cost less than North American ones. There are limited possibilities for financial aid.

PhDs often waive tuition fees and offer a living stipend in exchange for a teaching or research assistantship. However, they take many years to complete, during which time you earn very little.

This depends on the country. In the United States, you can generally go directly to a PhD  with only a bachelor’s degree, as a master’s program is included as part of the doctoral program.

Elsewhere, you generally need to graduate from a research-intensive master’s degree before continuing to the PhD.

This varies by country. In the United States, PhDs usually take between 5–7 years: 2 years of coursework followed by 3–5 years of independent research work to produce a dissertation.

In the rest of the world, students normally have a master’s degree before beginning the PhD, so they proceed directly to the research stage and complete a PhD in 3–5 years.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

It’s best to ask in person if possible, so first reach out and request a meeting to discuss your graduate school plans.

Let the potential recommender know which programs you’re applying to, and ask if they feel they can provide a strong letter of recommendation . A lukewarm recommendation can be the kiss of death for an application, so make sure your letter writers are enthusiastic about recommending you and your work!

Always remember to remain polite. Your recommenders are doing you a favor by taking the time to write a letter in support of your graduate school goals.

This depends on the program that you are applying for. Generally, for professional programs like business and policy school, you should ask managers who can speak to your future leadership potential and ability to succeed in your chosen career path.

However, in other graduate programs, you should mostly ask your former professors or research supervisors to write your recommendation letters , unless you have worked in a job that corresponds closely with your chosen field (e.g., as a full-time research assistant).

Choose people who know your work well and can speak to your ability to succeed in the program that you are applying to.

Remember, it is far more important to choose someone who knows you well than someone well-known. You may have taken classes with more prominent professors, but if they haven’t worked closely with you, they probably can’t write you a strong letter.

The sections in your graduate school resume depend on two things: your experience, and the focus of the program you’re applying to.

Always start with your education. If you have more than one degree, list the most recent one first.

The title and order of the other sections depend on what you want to emphasize. You might include things like:

• Professional experience
• Voluntary and extracurricular activities
• Publications
• Awards and honors
• Skills and certifications

The resume should aim for a balance between two things: giving a snapshot of what you’ve done with your life so far, and showing that you’re a good candidate for graduate study.

A resume is typically shorter than a CV, giving only the most relevant professional and educational highlights.

An academic CV should give full details of your education and career, including lists of publications and presentations, certifications, memberships, grants, and research projects. Because it is more comprehensive, it’s acceptable for an academic CV to be many pages long.

Note that, outside of the US, resume and CV are often used interchangeably.

No, don’t include your high school courses and grades. The education section should only detail your college education.

If you want to discuss aspects of high school in your graduate school application, you can include this in your personal statement .

A resume for a graduate school application is typically no more than 1–2 pages long.

Note, however, that if you are asked to submit a CV (curriculum vitae), you should give comprehensive details of all your academic experience. An academic CV can be much longer than a normal resume.

Always carefully check the instructions and adhere to any length requirements for each application.

If you’re applying to multiple graduate school programs, you should tailor your personal statement to each application.

Some applications provide a prompt or question. In this case, you might have to write a new personal statement from scratch: the most important task is to respond to what you have been asked.

If there’s no prompt or guidelines, you can re-use the same idea for your personal statement – but change the details wherever relevant, making sure to emphasize why you’re applying to this specific program.

If the application also includes other essays, such as a statement of purpose , you might have to revise your personal statement to avoid repeating the same information.

The typical length of a personal statement for graduate school applications is between 500 and 1,000 words.

Different programs have different requirements, so always check if there’s a minimum or maximum length and stick to the guidelines. If there is no recommended word count, aim for no more than 1-2 pages.

A statement of purpose is usually more formal, focusing on your academic or professional goals. It shouldn’t include anything that isn’t directly relevant to the application.

A personal statement can often be more creative. It might tell a story that isn’t directly related to the application, but that shows something about your personality, values, and motivations.

However, both types of document have the same overall goal: to demonstrate your potential as a graduate student and s how why you’re a great match for the program.

What is a doctorate.

A doctorate is a research-based academic degree. It is considered a terminal degree in most disciplines, meaning it represents the highest level of education a student can obtain in their chosen field.

A doctorate is awarded to students who have undergone a lengthy research process and made a significant contribution to the body of knowledge in their field of study. It takes multiple years to complete, during which students work closely with a supervisor and focus on a specific dissertation topic. Completing a doctorate might also involve teaching and comprehensive examinations.

A doctorate serves as solid proof of a person’s level of knowledge and expertise. It demonstrates that you have mastery over your chosen subject, and helps establish you as an expert. This level of expertise comes with top-tier job opportunities and the potential to earn top salaries in your chosen profession.

Doctorate vs PhD: Key Differences

While many people use the terms doctorate and PhD interchangeably, there are key differences between the two. These differences have to do with the application of these degrees. However, both terms refer to terminal degrees, so they hold the same value.

A Doctor of Philosophy degree, or PhD, is a research-oriented degree that demonstrates a person’s ability to contribute new knowledge to their chosen field. A student who pursues a PhD usually does so to answer a specific question, conduct original research to provide an answer, and use their findings to advance their field.

On the other hand, the term doctorate is broader and typically refers to a professional or clinical degree. This means that a person who obtains it has demonstrated an ability to apply advanced knowledge in a particular field in their professional life. Professional doctorates of this kind are awarded, for instance, to medical doctors or doctors of juridical science.

PhD Requirements: How to Get a PhD

While each PhD degree program will have unique requirements depending on the school and field of study, there are some common requirements you need to complete to get a PhD. Keep reading to find out about the most common requirements to earn your advanced degree.

PhD Statement of Purpose

A PhD statement of purpose is a document that clearly outlines your goals for your PhD, your academic credentials, and the reasons why an academic committee should approve your project. It is typically between 500 to 1,000 words long and gives prospective students an opportunity to explain how their research project will make a relevant contribution to their field.

How Many Credits Is a PhD?

Typically, it takes between 90 and 120 credits to complete your PhD studies. However, this number can be as low as 60, depending on the degree type, area of study, and state, regional, or institutional requirements. Credit hours for graduate students are usually divided between course work, research hours, and dissertation work.

Other Common Requirements for a PhD

• Coursework. While coursework is not the main focus of a PhD, students will usually have to enroll in a few core courses during their first or second year of grad school. They might also have the opportunity to enroll in elective courses, which offer a chance to learn about other fields of study.
• Qualifying exams. A common component of many PhD programs is a set of qualifying exams. Students must successfully pass these comprehensive exams toward the end of their degree in order to demonstrate their level of competence in their field. These tend to be oral exams.
• Teaching. Many PhD programs include a teaching component. Students are required to teach basic courses, typically to fresh undergrad students, which helps them develop teaching skills.
• Research. Conducting original research on a particular subject is typically the main component of a doctorate program, and takes up the bulk of doctoral candidates’ time.
• Dissertation. Throughout their program, PhD candidates need to complete a dissertation based on the original research they’ve conducted. Graduate students do this under the guidance of a qualified faculty member.
• Dissertation defense. Once the dissertation is approved, PhD students need to successfully defend their research in front of a panel of experts in their field before they are awarded their degree. This is the final step in the dissertation process.

How Do PhD Programs Work?

Typically, PhD degree programs work based on a mix of coursework and research conducted over three to four years, although this can last longer depending on the program and the pace at which a student completes their research. Coursework is typically completed towards the beginning of the program, and towards the end, the dissertation or thesis becomes the main focus.

In addition, students must fulfill other program requirements throughout this period. This might include teaching undergraduate students, completing a residency, passing qualifying exams, or attending conferences or colloquia. The final step is usually an oral defense in front of a panel of experts, who are selected to evaluate the quality of the research and the value of the results obtained.

Do You Need a Master’s to Get a PhD?

No, a master’s degree is not always required to pursue PhD studies. Many programs in the US allow students to apply to a PhD program straight after completing their bachelor’s degree. Other programs offer dual degrees, meaning that you will obtain a master’s degree while you work toward your doctorate.

What Comes After a Doctorate Degree?

In many fields, the usual step after a doctorate degree is a postdoc. This is an option for those wishing to pursue a career in academia and continue doing research in their field. However, an academic career is not the only option. Because a doctorate is a terminal degree, graduates can easily move on to professional positions in other types of organizations in their chosen field.

PhD Dissertation vs Thesis

The main difference between a dissertation and a thesis is the scope of the research being conducted and the type of degree you are awarded after completing it. Often, the terms are used interchangeably, or they can hold different meanings in European countries, which causes some confusion regarding their nature. Keep reading to understand the differences between a PhD dissertation and a thesis in the US.

What Is a PhD Dissertation?

A PhD dissertation is a piece of scholarly work that presents the original research carried out by a doctoral student during the length of their program. It discusses the scope, methodology, results, and conclusions of the research at length. The end goal of a doctoral dissertation is to produce results that help advance human knowledge in a given field.

PhD Dissertation Defense

A PhD dissertation defense is the process in which a PhD candidate defends their research in front of a panel of experts in their field. During the defense, members of the panel ask questions regarding the information presented, providing the candidate an opportunity to back up their work and demonstrate the level of expertise they’ve achieved after years of dedicated work.

What Is a PhD Thesis?

In the US, as opposed to some European countries, the term thesis refers to a shorter academic paper that is usually presented for the completion of a master’s degree. It can also sometimes be a requirement for honors students completing a bachelor’s degree. The information presented in a thesis is usually drawn from existing sources, rather than from original research conducted by the student.

PhD Thesis Defense

A thesis defense is usually not a mandatory requirement for master’s students, although this varies according to your school and department. The thesis is still an in-depth piece of scholarly writing and serves as a testament to a student’s mastery of a given subject, and a defense serves as an opportunity to engage a panel of experts and defend the contents of your paper.

How Long Does It Take to Earn a Doctorate?

Most doctoral programs are designed to be completed in four to six years. However, it can take up to seven and a half years to earn a doctoral degree from the start of graduate school, according to data presented by the National Science Foundation.

A number of factors can affect how long it takes students to earn their PhDs. They include the structure of their chosen program, the type of research being conducted, and the support provided by the institution. On average, students completing doctoral programs in science and engineering fields finish faster than their counterparts in non-science and engineering fields.

How Hard Is It to Get a PhD?

It can be very hard to get a PhD. Working for several years on a particular dissertation topic can be very trying. Aside from the time commitment, the depth of research that is part of the dissertation process can also be challenging. Admissions to a top education institution can be extremely competitive, as usually there are only a handful of positions available for hundreds of applicants.

What Is the Easiest PhD to Get?

PhDs in the humanities, social sciences, and education are typically regarded as the easiest to obtain. However, this truly comes down to how interested you are in your chosen dissertation topic and your level of commitment to making a relevant contribution to human knowledge, both of which can greatly influence your perception of the difficulty of the degree.

How Much Does a PhD Cost?

According to data from the National Center for Education Statistics, the average yearly cost of graduate programs in the US is $19,792. Data from the QS World University Rankings suggest that the yearly cost of a PhD in the US ranges from $28,000 to $40,000. The total cost of a PhD can greatly vary depending on the university, length of the program, and funding options available for doctoral study.

How to Earn a Doctoral Degree

So, how do you earn a doctoral degree? While there is work to be put in, the process is actually quite straightforward. Keep reading to find out how you can embark on the path toward your PhD.

The first step to earning your doctorate is to complete a bachelor’s degree at the undergraduate institution of your choice. Depending on your chosen field, you might need to obtain a degree in a specific discipline, which can then pave the way for your graduate studies.

If a bachelor’s degree is not an option right away, you can start by obtaining an associate degree , which can even be done through the best online community colleges . While you obtain your undergraduate degree, make sure to seek out career advice from experts who can help you decide how to best use your time and embark on the right academic path.

While earning a master’s degree is not mandatory to apply to a PhD program, doing so can offer you a competitive advantage. It will give you a chance to deepen your knowledge on a particular topic, connect with professors and gather recommendations, and test the waters regarding your chosen field.

In order to successfully apply to a master’s degree program, you will have to provide your GPA, letters of recommendation, and sometimes standardized test scores. For instance, if you’re interested in pursuing a Master’s Degree in Mathematics , you will need to prep for the GMAT and submit your scores. Be sure to check the requirements of your chosen school and department.

Whether you have completed your master’s or are applying straight after your bachelor's, make sure to spend some time choosing your specific research area and the type of PhD you wish to pursue. This is also an excellent time to assess funding opportunities and contact potential supervisors to gauge their interest in and ability to support you during your studies.

In order to enroll in a doctoral program, you will need to provide quite a few documents with your application. Every school is different, but the most common requirements are transcripts, letters of recommendation, and a strong statement of purpose. Make sure you check the specific requirements of your chosen program, and prepare to be interviewed by faculty members.

After being accepted into a doctoral program, you should outline what the next few years will look like. What requirements do you need to complete to earn your PhD? Spend time crafting a realistic timeline that can help you stay on track and complete every step successfully. This includes teaching, participating in conferences, and successfully completing your qualifying exams.

The final step to obtaining your PhD is to successfully complete your research and compile your results in your dissertation. Once it is reviewed and approved by your supervisor and readers, you will have to defend it as well. It can be a trying process, but the results will be worth it.

How to Choose a PhD Program

In order to choose a PhD program that is right for you, there are several factors you should consider. A PhD is a strong commitment both in terms of time and money, so the decision shouldn’t be made lightly. Keep reading to find out how to choose a PhD program.

PhD Acceptance Rates

The PhD acceptance rates of a university give you an idea of how likely you are to be admitted to your chosen program. This number is a reflection of how competitive a program is and the funding the department receives. Use this information to orient yourself to the selection process, as applying to a variety of programs with different acceptance rates can increase your chances of being accepted into one of them.

Keep in mind that acceptance rates are usually measured by department, not university. For instance, Columbia University has an acceptance rate of four to six percent for its psychology PhD program , and an acceptance rate of five to seven percent for its history PhD .

PhD Dropout Rates

PhD dropout rates are important to consider, as they give you an idea of how supported students are in a particular program and how likely you are to complete your doctorate. In the US, PhD attrition rates, or dropout rates, can range from 40 to 50 percent , so take your time to find a university and program with a high success rate to ensure you will be able to finish and obtain your degree.

Faculty Members

One of the key relationships you will have during your time as a PhD student will be with your supervisor. You will also be working closely with other members of your department. As such, make sure to research the faculty to ensure that their interests and research projects align with your own. During the research stage, you can even reach out to them to find out about the department, ask about funding opportunities, and receive relevant career advice.

Funding Opportunities

A PhD can be costly, but there are many ways to offset those costs to make it more manageable. Be it scholarships, grants, or work opportunities, make sure to research all funding opportunities available so you can select a program that aligns with your financial situation. Many universities offer fully-funded programs to outstanding students, so do your homework and find a program that doesn’t leave you financially crippled in the long run.

When you commit to a PhD, you are also committing to several years of work. Unless you are planning to complete your program fully online, you should take into account the place where you will be moving to continue your studies.

Do you prefer big cities or small college towns? Which part of the country would you be willing to relocate to? Take some time to reflect on your preferences so you can choose the best location according to your needs and preferences.

Doctoral Degree, Doctorate

College degree finder, what is a doctoral degree.

A doctoral degree, or doctorate, is a graduate level academic or professional degree. In the United States it is considered the highest degree an individual can earn in a given field of study, and as such, it is often referred to as a terminal degree.

Time It Takes To Earn a Doctoral Degree

A doctorate can anywhere from 2 years (e.g. Doctor of Nursing Practice ) to 10 years to complete. Most doctoral graduates, however, take an average of 8.2 years to complete (post bachelor’s degree) their degree and are 33 years old upon earning their doctorate diploma. Additionally, about 57% of doctoral students will take 10 years to finish.

If you hold master’s degree in the same subject area you’re pursuing a doctoral degree, it may only take three years of additional study to complete. This degree will require 60 to 120 semester credit hours or approximately 20 to 40 college courses. However, the length of your doctoral degree will depend on your educational background, the institution offering it, and the subject area you’re studying.

The Growth of Doctoral Degrees

While a doctorate is required for very few careers, it is growing in popularity, not only among academics but professionals too. A growing number of online doctoral degrees are designed as “practitioner’s degrees”, specifically for aspiring professionals. Furthermore, in areas where state licensing is required, such as teaching in public schools and colleges, engineering and psychology, a doctoral degree is highly beneficial, if not mandatory. Research positions at universities, government agencies, corporations and private research facilities may also require employees to have a doctorate.

In fact, the number of doctorate degrees conferred each year has grown 5% from 2011 to 2015. By the year 2025, it is estimated that the number of doctorate degrees conferred each year will grow by another 12% (from 178k in 2015 to 200k).

Most Popular Doctorate Fields

According to the NCES , Of the 179,000 doctor’s degrees conferred in 2015, almost two-thirds were within health profession concentrations and legal professions and studies.

Types of Doctoral Degrees

Over the last few centuries, there has been substantial evolution and proliferation in the number and types of doctoral degrees. Historically, these degrees would entitle the holder to addressed as “doctor”, however, that isn’t as true today. Whether an individual will have that title depends in large part on the type of degree earned as well as the subject area. The following are general classifications of doctoral degrees.

Professional Doctoral Degree

Professional doctorates are degrees that are awarded in fields where advanced study and research are aligned with a specific profession, such as psychology, medicine, engineering, education, or law. These advanced degrees are particularly common in the United States and Canada.

Popular Professional Doctorates – U.S. and Canada

• Doctor of Chiropractic (DC)
• Doctor of Dental Medicine (DMD)
• Doctor of Nursing Practice (DNP)
• Doctor of Ministry (DMin)
• Doctor of Occupational Therapy (OTD)
• Doctor of Optometry (OD)
• Doctor of Osteopathic Medicine (DO)
• Doctor of Pharmacy (PharmD)
• Doctor of Physical Therapy (DPT)
• Doctor of Practical Theology (DPT)
• Doctor of Public Administration (DPA)
• Doctor of Social Work (DSW)
• Doctor of Veterinary Medicine (DVM)
• Juris Doctor (JD)
• Medicinae Doctor (MD)

Professional doctoral degrees took hold in the United States around 1767 when Columbia University introduced the MD. A hundred years later, in 1861, later Yale University introduced the nation’s first PhD or research doctorate. Shortly thereafter, Havard University introduced the Juris Doctor (JD) which took hold nationwide. These degrees, sometimes referred to as first professional degrees , were created in an effort to strengthen professional training programs. These advanced degrees have since been introduced in other fields as well, such as the Doctor of Audiology in 2007 and Doctor of Nursing Practice (DNP) in 2008.

The term “Professional Doctorate” makes specific reference to a degree that focuses on applied research, or research that is designed to be used specifically for professional purposes.

Research Doctoral Degree

Research doctorates are awarded by colleges and universities throughout the world. These doctoral degrees are awarded to candidates who have conducted research that is publishable in a peer-reviewed academic journal. In the United States, to earn a research doctorate an individual must also complete substantial coursework beyond the masters level. The most common research doctoral degree in the United States, Great Britain, and Canada is the Doctor of Philosophy, or PhD.

Other popular doctorates include the Doctor of Education (Ed.D.), Doctor of Engineering (D.Eng.), and Doctor of Theology (ThD). The ThD, as suggested by its name, is a research doctorate in theology, awarded by both secular and religious institutions including the University of Toronto and Harvard Divinity School, to name some examples. Another research degree, the Doctor of Sacred Theology (STD), is a specific ThD degree offered by Catholic Pontifical Universities and institutions.

Popular Research Doctoral Degree Titles – U.S.

• Doctor of Arts (DA)
• Doctor of Business Administration (DBA)
• Doctor of Design (D.Des.)
• Doctor of Education (Ed.D.)
• Doctor of Engineering (D.Eng./D.E.Sc./D.E.S.)
• Doctor of Fine Arts (DFA)
• Doctor of Industrial Technology (DIT)
• Doctor of Music (DM)
• Doctor of Nursing Science (DN.Sc.)
• Doctor of Philosophy (PhD)
• Doctor of Physical Education (DPE)
• Doctor of Public Health (DPH)
• Doctor of Science (DSc/ScD)
• Doctor of Theology (ThD)

To see a full list of research doctoral degrees, download this list from the U.S. Department of Education.

Time Requirement for a Research Doctorate Degree

While the criteria for earning a research doctorate may vary from one country to another, most research doctoral degree programs require that a candidate conducts a substantial amount of publishable research. Frequently, candidates are also required to develop an original thesis or dissertation, present a portfolio of research reports and project to be reviewed by a committee, and undergo an oral examination. As previously mentioned, as is the case in the United States, candidates may also have to complete a series of graduate-level courses in the subject area of their doctorate.

The minimum time required to complete a research doctorate is about three years but it often can take over six years to complete.

International Tiers of Doctorates

In several countries outside the United States, including Australia, England, Ireland and a few Scandinavian countries, there is a tier of awards based on a very high standard of research. Individuals who earn these degrees are typically required to submit an extensive portfolio of research published in reputable journals and subject relevant publications. Examples of these degrees include Doctor of Sciences (DSc/ScD), Doctor of Letters (DLitt/LittD), Dr. Theol. (Theology), Dr. Jur. (Law), and Dr. Med. (Medicine). Higher doctorates are sometimes awarded as Honory Degrees in recognition of accomplishment and/or contribution to a particular field.

In several countries outside of the U.S., including the United Kingdom and Russia, there are degrees, known as higher doctorates which are more advanced than a professional doctorate or traditional research PhD.

Honorary Doctoral Degree

When a doctoral degree is awarded honoris causa (“for the sake of the honor”) it’s known as an honorary doctoral degree. Honorary doctorates are awarded based on an individual’s achievement or contribution to a particular field or philanthropic cause. In such case, the awarding college or university typically waives all the usual requirements, such as matriculation, residence, study, and the passing of examinations. While these degrees are not uncommon, many universities including the University of Virginia, Cornell University, Massachusetts Institute of Technology, and California Institute of Technology, as well as many other institutions do not offer or award these degrees.

Terminal Academic Research Degrees

A doctorate degree, such as a Doctor of Philosophy (PhD), is considered the highest academic degree in a particular field of study in some countries, including the United States. These degrees are considered terminal because there is no higher degree that can be awarded. However, many professional doctorates , while considered terminal within the profession, may only serve as prerequisites to research degrees in the same subject area.

You may be wondering what is a PhD degree, what are PhD requirements, and what it means to earn a PhD. At this point, you may be questioning if getting a PhD is the right next step for you.

To receive a PhD, you will add the title “Dr.” to you name, but there is much more to it than that. Here, we will dive into what a PhD means, what it takes to earn one, the different kinds of PhD degrees that exist, and the reasons why you may choose to take the path to graduate with one.

What is a PhD?

First thing’s first, let’s define all the ins and outs of what a PhD means. PhD is an abbreviation for “Doctor of Philosophy.”

A PhD is the ultimate academic degree you can earn in a field of choice. To earn a PhD, you must complete original research and evaluate a theory. More often than not, this includes data analysis. This fact is true no matter where you are in the world.

Unlike undergraduate degrees, a PhD is heavily focused on research. As such, lectures are not all that common when working towards earning the degree, but they do still exist. Rather, students will focus particularly on an aspect of the subject choice to create a dissertation. Along with a written thesis, students must present their work orally (known as a “viva voce”) to a group of examiners.

A PhD is recognized around the world as the highest academic achievement. Therefore, no matter where you go, it bears with it an international standard of understanding and a level of respect. It allows for you to be a professor in academia and work in a highly specialized position within the field.

Requirements and Length of Time

While the payoffs of a PhD may seem enticing, the journey to earn your PhD is not an easy or short one.

More often than not, a PhD comes after a master degree. Yet, that’s not always true. Some institutions allow students to skip the master degree and move straight from a bachelor degree into a PhD program.

The time length of a PhD program can vary, but it generally takes three to four years to complete. If a student chooses to study part-time, it could take upwards of six or seven years to graduate.

In order to be accepted into a PhD program, there are a variety of PhD requirements. The most important requirement tends to be proof of high academic standing from your master degree. Some schools may also factor in your bachelor degree grades.

Grades also play a role in assessing the type of funding you may receive. If you have low grades, but still want to pursue a PhD, you’ll likely have to self-fund.

Along with grades, most institutions will also require the following:

1. Proof of language proficiency in the language you will pursue your PhD.

2. resume of work experience and transcript of academic courses., 3. a personal statement sharing your reasons why you want to pursue a phd in your respective field and perhaps why you are choosing the institution., 4. a phd research proposal, which includes:.

• Your proposed research topic
• Experience regarding the subject matter
• Gaps in current knowledge, your understanding of current findings
• Your research methodology
• How your research and its implications will affect the world

How to get a phd.

Getting a PhD requires planning, research, and commitment. Some schools vary in their requirements to apply, so it’s best practice to create your list of desired schools and research their needs.

You can choose to get a PhD at any age, but it’s best to start thinking proactively when you are moving along your graduate degree program.

Here are the main steps it takes to get a PhD:

1. Get a bachelor’s degree

2. complete the gre, 3. apply to graduate schools, 4. begin master’s or phd program, 5. if master’s, graduate and then apply again for a phd program, 6. complete phd coursework, 7. start research and write a dissertation, 8. share dissertation and get published, 9. graduate with a phd, types of phd.

There are different categories of PhD degrees. However, students only choose between professional and academic. Higher and honorary PhDs are awarded later in one’s career.

These include:

Granted in traditional subjects by performing academic research (PhD/Doctor of Philosophy/Th.D – Doctor of Theology)

Professional

These contribute directly to a specific vocational field (Doctor of Business Administration, Doctor of Engineering, Doctor of Education, Doctor of Social Science, Doctor of Architecture, etc.)

Higher/Honorary

To honor esteemed researchers and professionals, an honorary PhD may be rewarded (Doctor of Divinity, Doctor of Science – Science, Technology, Engineering and Math, Doctor of Science – Arts and Humanities)

Reasons to Get a PhD

Everyone has their own reasons for why they want to get their PhD. Here are some motivations behind why you may choose to pursue the degree:

1. Intellectual challenge:

As the final degree in academics, a PhD will challenge your intellectual abilities.

2. Career goals:

Your chosen career requires that you have the degree (i.e., becoming a professor).

3. Personal passion:

You enjoy the subject matter and want to be an expert in the field.

4. Research:

You have something to contribute or know how to fill a gap in the current information.

The bottom line.

Earning a Doctor of Philosophy degree is not only for those who wish to become a professor . Whether your future career requires the degree or not, you may still want to pursue the academic challenge.

The most common trait of a PhD relies on research. As such, a government agency or organization may also want to fund you in performing research if you have something worthwhile to contribute to your field of study.

As the ultimate destination in terms of degrees, the title of PhD next to your name is well-respected and universally acknowledged. However, before enrolling in a program, make sure that you have the time, resources, and personal passion to fulfill all the necessary requirements.

Ph.D. Program

Click  here for the Handbook for Graduate Study in English .  This document includes departmental policies and procedures concerned with graduate study.

The Berkeley English Department offers a wide-ranging Ph.D. program, engaging in all historical periods of British and American literature, Anglophone literature, and critical and cultural theory. The program aims to assure that students gain a broad knowledge of literature in English as well as the highly-developed skills in scholarship and criticism necessary to do solid and innovative work in their chosen specialized fields.

Please note that the department does not offer a Master’s Degree program or a degree program in Creative Writing. Students can, however, petition for an M.A. in English with an emphasis in Creative Writing upon completion of the Ph.D. course requirements (one of which must be a graduate writing workshop) and submission of a body of creative work.

Students interested in combining a Ph.D. in English with studies in another discipline may pursue Designated Emphases or Concurrent Degrees in a number of different fields

Normative time to complete the program is six years. The first two years are devoted to fulfilling the course and language requirements. The third year is spent preparing for and taking the Ph.D. oral qualifying examination. The fourth through sixth years are devoted to researching and writing the prospectus and dissertation.

The general goal of the first two years is to assure that the students have a broad and varied knowledge of the fields of British and American literature in their historical dimensions, and are also familiar with a wide range of literary forms, critical approaches, and scholarly methods. Students will complete twelve courses distributed as follows:

• 1) English 200, “Problems in the Study of Literature”
• 2) Medieval through 16 th -Century
• 3) 17 th - through 18 th -Century
• 4) 19 th -Century
• 5) 20 th -Century
• 6) a course organized in terms other than chronological coverage.
• 7-12) Elective courses.

(A thirteenth required course in pedagogy can be taken later.) Students who have done prior graduate course work may transfer up to three courses for credit toward the 12-course requirement. Up to five of the 12 courses may be taken in other departments.

Students must demonstrate either proficiency in two foreign languages or advanced knowledge in one foreign language before the qualifying examination. There are no "canonical languages" in the department. Rather, each specifies which languages are to count, how they relate to the student's intellectual interests, and on which level knowledge is to be demonstrated. "Proficiency" is understood as the ability to translate (with a dictionary) a passage of about 300 words into idiomatic English prose in ninety minutes. The proficiency requirement may also be satisfied by completing one upper-division or graduate literature course in a foreign language. The advanced knowledge requirement is satisfied by completing two or three literature courses in the language with a grade of "B" or better.

At the end of the second year each student’s record is reviewed in its entirety to determine whether or not he or she is able and ready to proceed to the qualifying exam and the more specialized phase of the program.

The Qualifying Examination

Students are expected to take the qualifying examination within one year after completing course and language requirements. The qualifying exam is oral and is conducted by a committee of five faculty members. The exam lasts approximately two hours and consists of three parts: two comprehensive historical fields and a third field which explores a topic in preparation for the dissertation. The exam is meant both as a culmination of course work and as a test of readiness for the dissertation.

The Prospectus and Dissertation

The prospectus consists of an essay and bibliography setting forth the nature of the research project, its relation to existing scholarship and criticism on the subject, and its anticipated value. Each candidate must have a prospectus conference with the members of their committee and the Graduate Chair to discuss the issues outlined in the proposal and to give final approval to the project. The prospectus should be approved within one or two semesters following the qualifying exam.

The dissertation is the culmination of the student's graduate career and is expected to be a substantial and original work of scholarship or criticism. Students within normative time complete the dissertation in their fourth through sixth years.

Seven graduate students honored with Doctoral Dissertation Fellowships

MINNEAPOLIS / ST. PAUL (7/18/2024) – Seven graduate students advised by Department of Chemistry faculty members were recently awarded the University of Minnesota’s Doctoral Dissertation Fellowship. The seven students honored by this prestigious award are Kaylee Barr, Brylon Denman, Madeline Honig, Chris Seong, Sneha Venkatachalapathy, Murphi Williams, and Caini Zheng.

Kaylee Barr , a Chemical Engineering and Materials Science PhD student, is entering her fifth year in the Reineke Group . Before making the move to Minnesota, she received her BS in Chemical Engineering from the University of Kansas. “I came to the University of Minnesota because of the department's developments in polymer science, and because I was interested in the intersection of polymer science and drug delivery in Theresa Reineke's lab,” she says. Here at UMN, Kaylee studies how bottlebrush polymer architecture affects pH-responsive oral drug delivery. This summer, she is excited to grow professionally and as a scientist in an intern position at Genentech.

Brylon Denman is a Chemistry PhD candidate in the Roberts Group . She joined the UMN community in 2020 after completing her BS in Biochemistry at St. Louis University. “My research in the Roberts group seeks to resolve regioselectivity and reactivity issues within aryne methodology via ligand control,” Brylon says. “To accomplish this task, I have taken a mechanistic and hypothesis driven approach to understand how key molecular parameters modify regioselectivity and reactivity. I hope to use the knowledge I have gained from these studies to both improve the synthetic utility of aryne intermediates, and improve the sustainability of aryne reactions.” Brylon is also passionate about sustainable and green chemistry. As a founding member of the Sustainable and Green Chemistry committee, Brylon strives to collaborate with other department teammates to strengthen the culture of green and sustainable chemistry through integration into teaching, research, and community engagement. “In my career I aim to continue this advocacy and use my breadth of knowledge to enact sustainable change at a major pharmaceutical company as emphasizing sustainability on such a large scale can lead to a large impact,” she says. As she works through her internship at AbbVie this summer, Brylon is looking towards the future to outline her next steps after graduation.

Madeline Honig first experienced Chemistry at UMN during a summer REU experience in the Bühlmann Lab . She formally joined the Prof. Bühlmann's team in Fall 2020 after earning her BA in Chemistry from Earlham College. Her research here at UMN  has focused on the development and improved understanding of polymeric membrane-based ion-selective electrodes (ISEs). “One of my projects involves developing a quantitative parameter to better define the upper detection limits of these sensors which can be used to more accurately define sensor performance and predict the working range under different conditions,” Madeline says. “This research led us to investigate the unexplained 'super-Nernstian' responses of some pH-selective electrodes and expand the phase boundary model (the quantitative model that predicts ISE behavior) to include the formation of complexes between protonated ionophores and counter-ions in the sensing membrane. ISEs have been widely used for decades in clinical blood analysis among many other applications so it's exciting that I was still able to add to our fundamental understanding of how these sensors function.” One of Madeline’s goals is to use her research to enable the development of improved sensors that can be used in a wider range of conditions. Over the course of her graduate studies, Madeline has had the opportunity to be a graduate student mentor for two other students: Ariki Haba, a visiting master's student from Japan, and Katie O'Leary, a summer REU student, who both made significant contributions to the project. “Acting as a graduate mentor was really cool and I hope I can also make graduate-level chemistry research more approachable for everyone that I work with,” Madeline says. For her significant research efforts, Madeline was also recently selected in a national competition as one of the four winners of the 2024 Eastern Analytical Symposium Graduate Student Research Award. She will accept the award in November in Plainsboro NJ at the Eastern Analytical Symposium.

Chris Seong , an international student from New Zealand and PhD candidate in the Roberts Group, came to UMN after completing his BA with Distinction in Chemistry at St. Olaf College in 2020. Chris’ overarching chemistry interests involve the development of methods to utilize naturally abundant carboxylic acids as feedstock to synthesize medicinally relevant products, which are traditionally made with non-renewable starting materials derived from fossil fuels. “My earlier work has been focused on making alkyl-alkyl bonds through decarboxylation, but lately, in true Roberts Group fashion, I have turned my attention to using a similar mechanism to do aryne chemistry,” Chris says. He is currently working to publish a paper on the aryne project that he has been working on with two talented group mates; Sal Kargbo and Felicia Yu. “I am really excited to share this cool chemistry with the world,” he says. Outside of the lab, Chris is working on expanding his network to apply for jobs in the pharmaceutical industry – specifically in the early process space.

Sneha Venkatachalapathy is a member of the Distefano Group and an international student from India. She completed her BS in Chemistry with a minor degree in Biotechnology from Shiv Nadar University, Greater Noida, India in 2020. “Chemistry has always been my passion since high school. I still remember my first successful brown ring test that has left a remarkable fascination and interest towards chemistry,” Sneha says. “This early fascination has driven my academic journey, guided by mentors like Dr. Subhabrata Sen, who encouraged me to pursue a PhD in the United States.” Sneha was drawn towards working in the Chemical Biology research field where she could directly contribute to developing human life. “Joining Dr. Mark Distefano’s lab at UMN provided me with the chance to collaborate with Dr. Mohammad Rashidian from Dana Farber Cancer Institute. Together, we work towards expanding the scope of protein prenylation to construct protein-based cancer diagnostic tools,” she says. Sneha’s goal for her time in the UMN PhD program is to create innovative protein-based tools for cancer detection and treatment, aiming to enhance patient’s quality of life. She says she is looking forward to continuing to develop her leadership skills as she continues her doctorate, and is also exploring future opportunities beyond UMN. “One thing that motivates me daily is the belief that my research contributions to the scientific community would enhance our understanding of cancer diagnostic methods, ultimately leading to improved patient outcomes worldwide,” she says.

Murphi Williams  completed her undergraduate studies at the University of Wisconsin-Eau Claire, then joined the Bhagi-Damodaran at UMN in 2020. When it comes to research, Murphi is interested in chemical biology, more specifically, looking into proteins involved in important biological problems. “One of my major projects is developing and characterizing a potential inhibitor for  Mycobacterium tuberculosis , the bacteria that causes tuberculosis,” Murphi says. “Tuberculosis is the leading infectious disease so my projects center on understanding and inhibiting heme proteins important for the bacteria. Specifically, a previous lab member identified a small molecule that I've been characterizing the activity of in cells.” Her current research goal is to express and purify the protein targets for her small molecule inhibitor in the lab to further demonstrate the in vitro activity. She is also contemplating a future career in science communication. Outside of the lab, she enjoys working on her garden. 

Caini Zheng joined the Chemistry at the UMN in 2019 after finishing her undergraduate studies at Shanghai Jiao Tong University. She is currently a sixth-year graduate student co-advised by Profs. Tim Lodge and Ilja Siepmann . Her research focuses on the phase behavior of soft materials, including polymers and oligomers. Her DDF statement is titled "Self-Assembly of Polymers and Amphiphiles into Bicontinuous Phases". Caini is currently working on a project to elucidate the self-assembly of glycolipids through molecular dynamics simulations coupled with machine learning methods. In the future, she wants to work in the industry on bridging data science with traditional material research.
