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 Doctorate Degree?

A doctorate is usually the most advanced degree someone can get in an academic discipline, higher education experts say.

What Is a Doctorate?

It's unwise to apply to a doctoral program if you don't have a clear idea of how you might use a doctorate in your career.

In many academic disciplines, the most advanced degree one can earn is a doctorate. Doctorate degree-holders are typically regarded as authorities in their fields, and many note that a major reason for pursuing a doctorate is to increase professional credibility.

"If someone wants to be respected as an expert in their chosen field, and also wants to have a wider array of options in research, writing, publishing, teaching, administration, management, and/or private practice, a doctorate is most definitely worth considering," Don Martin, who has a Ph.D. in higher education administration , wrote in an email.

A doctoral degree is a graduate-level credential typically granted after multiple years of graduate school, with the time-to-degree varying depending on the type of doctoral program, experts say.

Earning a doctorate usually requires at least four years of effort and may entail eight years, depending on the complexity of a program's graduation requirements. It also typically requires a dissertation, a lengthy academic paper based on original research that must be vetted and approved by a panel of professors and later successfully defended before them for the doctorate to be granted.

Some jobs require a doctorate, such as certain college professor positions, says Eric Endlich, founder of Top College Consultants, an admissions consulting firm that helps neurodivergent students navigate undergraduate and graduate school admissions.

Endlich earned a Doctor of Philosophy degree, commonly known as a Ph.D., from Boston University in Massachusetts. He focused on psychology and notes that a doctoral degree is generally required to be a licensed psychologist.

"Since a Ph.D. is a research-focused degree, it can be advantageous to those seeking high-level research positions in scientific fields such as astrophysics or biotechnology," he says.

How Long it Takes to Get a Doctorate Degree

Martin, founder and CEO of Grad School Road Map, an organization that helps grad school applicants navigate the admissions process, says obtaining a doctorate is often a lengthy endeavor.

"Typically it can take between four and six years to complete any doctoral program," he says. "If comprehensive examinations and a dissertation are part of the graduation requirements, it may take a year or two longer. There is no standard amount of time – some students take seven to 10 years to finish."

Endlich says doctoral degree hopefuls should be aware that completing a dissertation may take a long time, especially if unexpected hurdles arise.

"My dissertation, for example, involved recruiting college students to complete questionnaires, and it took much longer than I anticipated to recruit enough subjects for my study," he says.

The standards for a dissertation, which include the proposal and research, are rigorous and usually involve a review and approval by a faculty committee, says Hala Madanat, vice president for research and innovation at San Diego State University in California.

"As part of dissertation requirements, some programs will require publication of the research in high-impact peer-reviewed journals," Madanat wrote in an email.

Types of Doctoral Degree Programs

According to professors and administrators of doctoral programs, there are two types of doctorates.

Doctor of Philosophy

A doctor of philosophy degree is designed to prepare people for research careers at a university or in industry, and teach students how to discover new knowledge within their academic discipline. Ph.D. degrees are offered in a wide range of academic subjects, including highly technical fields like biology , physics, math and engineering; social sciences like sociology and economics; and humanities disciplines like philosophy.

A Ph.D. is the most common degree type among tenure-track college and university faculty, who are typically expected to have a doctorate. But academia is not the only path for someone who pursues a Ph.D. It's common for individuals with biology doctorates to work as researchers in the pharmaceutical industry, and many government expert positions also require a Ph.D.

Professional or clinical doctorates

These are designed to give people the practical skills necessary to be influential leaders within a specific industry or employment setting, such as business, psychology , education or nursing . Examples of professional doctoral degrees include a Doctor of Business Administration degree, typically known as a DBA; a Doctor of Education degree, or Ed.D.; and a Doctor of Nursing Practice degree, or DNP.

A law degree, known as a juris doctor or J.D., as well as a Doctor of Medicine degree, or M.D., are also considered professional doctorates.

How to Get a Doctorate

Getting a doctorate is challenging. It ordinarily requires a series of rigorous classes in a field of study and then passage of a qualification exam in order to begin work on a dissertation, which is the final project.

Dissertations are difficult to write, says David Harpool, vice president of graduate and online programs at Newberry College in South Carolina. Some research indicates that only about half of doctoral students go on to finish their degree, and a main reason is that many never finish and successfully defend their dissertation

"Many of them are in programs that permit them to earn a master’s on the way to a doctorate," Harpool, who earned a Ph.D. from Saint Louis University in Missouri and a J.D. from the University of Missouri , wrote in an email. "The transition from mastering a discipline to creating new knowledge (or at least applying new knowledge in a different way), is difficult, even for outstanding students."

Learn about how M.D.-Ph.D. programs

There is a often a "huge shift in culture" at doctoral programs compared to undergraduate or master's level programs, says Angela Warfield, who earned a Ph.D. in English from the University of Iowa.

Doctoral professors and students have more of a collaborative relationship where they function as colleagues, she says. And there's pressure on each student to produce "significant and original research."

Many full-time doctoral students work for the school as researchers or teaching assistants throughout their program, so time management is crucial to avoid burnout. However, the dissertation "is by far the biggest battle," she says. The goal is to avoid an "ABD," she says, meaning "all but dissertation."

"In my writing group, we had two motivational slogans: 'ABD is not a degree,' and 'a good dissertation is a done dissertation,'" Warfield, now the principal consultant and founder of admissions consulting firm Compass Academics, wrote in an email.

How Are Doctorate Admissions Decisions Made?

Admissions standards for doctoral programs vary depending on the type of doctorate, experts say.

The quality of a candidate's research is a distinguishing factor in admissions decisions, Madanat says. Meanwhile, leaders of clinical and professional doctorate programs say that the quality of a prospective student's work experience matters most.

Doctoral programs typically expect students to have a strong undergraduate transcript , excellent letters of recommendation and, in some cases, high scores on the Graduate Record Examination , or GRE, Endlich says.

"The size of the programs may be relatively small, and universities need to be sure that applicants will be able to handle the demands of their programs," he says.

Because professional doctorates often require students to come up with effective solutions to systemic problems, eligibility for these doctorates is often restricted to applicants with extensive first-hand work experience with these problems, according to recipients of professional doctorates.

In contrast, it's common for Ph.D. students to begin their programs immediately after receiving an undergraduate degree. The admissions criteria at Ph.D. programs emphasize undergraduate grades, standardized test scores and research projects , and these programs don't necessarily require work experience.

Admissions decisions may also depend on available funding, says Madanat, who works with doctoral students to provide funding, workshops and faculty support to help their research.

Who Is a Good Fit for a Doctoral Program?

Doctoral degree hopefuls "should be interested in making a deep impact on their field, open-minded, eager to learn, curious, adaptable and self-motivated," Madanat says. "Doctoral programs are best suited for those whose goals are to transform and change the fields they are studying and want to make a difference in the way the world is."

Someone who loves to study a subject in great depth, can work alone or in teams, is highly motivated and wants to develop research skills may be a good candidate for a doctoral program, Endlich says.

Because of the tremendous effort and time investment involved in earning a doctorate, experts say it's foolish to apply to a doctoral program if it's unclear how you might use a doctorate in your career.

"The students are being trained with depth of knowledge in the discipline to prepare them for critical thinking beyond the current state of the field," Madanat says. "Students should consider the reasons that they are pursuing a doctoral degree and whether or not it aligns with their future professional goals, their family circumstances and finances."

Rachel D. Miller, a licensed marriage and family therapist who completed a Ph.D. degree in couples and family therapy at Adler University in Illinois in 2023, says pursuing a doctorate required her to make significant personal sacrifices because she had to take on large student loans and she needed to devote a lot of time and energy to her program. Miller says balancing work, home life and health issues with the demands of a Ph.D. program was difficult.

For some students, the financial component may be hard to overlook, Warfield notes.

"Student debt is no joke, and students pursuing graduate work are likely only compounding undergraduate debt," she says. "They need to really consider the payoff potential of the time and money sacrifice."

To offset costs, some programs are fully funded, waiving tuition and fees and providing an annual stipend. Some offer health insurance and other benefits. Students can also earn money by teaching at the university or through fellowships, but those adding more to their plate should possess strong time management skills, experts say.

"Graduate school, and higher education in general, can be brutal on your physical and mental health," Miller wrote in an email.

But Miller says the time and effort invested in her doctoral program paid off by allowing her to conduct meaningful research into the best way to provide therapy to children affected by high-conflict divorce and domestic violence. She now owns a therapy practice in Chicago.

Miller urges prospective doctoral students to reflect on whether getting a doctorate is necessary for them to achieve their dream job. "Really know yourself. Know your purpose for pursuing it, because that's what's going to help carry you through."

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.

What is a PhD? Advice for PhD students

How long does it take to get a doctorate degree how do you get into grad school are you qualified to do a phd answers to these questions and more.

PhD, doctorate

What is a PhD?

A PhD, which stands for “doctor of philosophy”, is the most advanced academic degree. It’s earned through extensive research on a specific topic, demonstrating expertise and contributing new knowledge to the field.

What does “PhD” mean?

The term “PhD” is often used as a synonym for any doctoral-level qualification. Doctorate degrees can often be split into two categories: MPhil and PhD.

An MPhil is similar to a PhD as it includes a research element (which is usually shorter and less in-depth than a PhD thesis, and often more akin to a dissertation undertaken at undergraduate or master’s level). 

MPhil students focus more on interpreting existing knowledge and theory and critically evaluating other people’s work rather than producing their own research. The precise nature and definition of an MPhil can vary among institutions and countries. 

A PhD, meanwhile, follows a more widely known and traditional route and requires students, often referred to as “candidates”, to produce their own work and research on a new area or topic to a high academic standard.

PhD requirements vary significantly among countries and institutions. The PhD, once completed, grants the successful candidate the title of “doctor of philosophy”, also called PhD or DPhil.

What is a professional doctorate?

A professional doctorate is a kind of degree that helps people become experts in their fields. Instead of focusing mainly on theory and research like a regular PhD, a professional doctorate is all about practical skills and knowledge.

This kind of doctorate is great for students who want to get better at their jobs in areas like teaching, healthcare, business, law or psychology. The courses and projects in these programmes are designed to tackle real problems you might face at work.

For example, you might have heard of the doctor of education (EdD), doctor of business administration (DBA), doctor of psychology (PsyD) or doctor of nursing practice (DNP). These programmes combine learning, hands-on projects and sometimes a thesis paper or essay to show you’re skilled at solving on-the-job challenges.

How long does it take to study a PhD?

The time required to complete a PhD can vary significantly based on several factors. Generally, a full-time PhD programme takes around three to six years to finish. However, it’s important to take into account individual circumstances and the nature of the research involved.

1. Full-time vs. part-time: If you’re studying full-time, dedicating most of your time to your studies, it usually takes about three to four years to complete a PhD. However, studying part-time while managing other commitments might extend the duration. Part-time PhDs can take around six to eight years, and sometimes even longer.

2. Nature of research: The complexity of your research proposal can influence the time required. Certain research questions may involve intricate experiments, extensive data collection or in-depth analysis, potentially leading to a longer completion timeline.

3. Field of study: The subject area you’re researching can also affect the necessary time. Some fields, such as sciences or engineering, might involve more hands-on work, while theoretical subjects might require more time for literature review and analysis.

4. Supervision and support: The guidance and availability of your academic supervisor can affect the pace of your research progress. Regular meetings and effective communication can help keep your studies on track.

5. Thesis writing: While the research phase is crucial, the stage of writing your thesis is equally significant. Organising and presenting your research findings in a clear and cohesive manner can take several months.

6. External commitments: Personal commitments, such as work, family or health-related factors, can influence your study time. Some students need to balance these alongside their PhD studies, potentially extending the duration.

7. External Funding: The availability of funding can also affect your study duration. Some funding might be linked to specific project timelines or research objectives.

So, although a PhD usually takes between three and six years of full-time study, with potential variations based on research complexity, enrolment as part-time or full-time, field of study and personal circumstances. It’s vital to have a realistic understanding of these factors when planning your PhD journey.

How long is a PhD in the UK?

In the UK, the length of a PhD programme typically ranges from three to four years of full-time study. As explained above, there are many factors to consider.

How long is a PhD in the US?

Similarly to the UK, in the United States, the duration of a PhD programme can vary widely depending on the field of study, research topic and individual circumstances. On average, a full-time PhD programme in the US typically takes between five and six years to complete.

Why does it take longer to study a PhD in the US?

PhD programmes generally take longer to complete in the US than in the UK due to various factors in the education systems and programme structures of each country:

1. Programme structure: UK PhD programmes often emphasise early, focused research from the first year, leading to shorter completion times. In contrast, US programmes commonly include more initial coursework in your first and second year and broader foundational training, which can extend the overall duration.

2. Course work requirements: Many US PhD programmes require a lot of course work, which can lengthen the time needed to finish. UK programmes tend to have fewer or no course work demands, allowing students to concentrate primarily on research skills.

3. Research funding: In the UK, PhD funding is often awarded with specific timeframes in mind, motivating completion of the research degree in the agreed duration. In the US, funding approaches can vary, requiring students to secure funding from multiple sources, potentially affecting their progress and completion time.

4. Teaching responsibilities: Some US PhD students take on teaching roles as part of their funding, dividing their time and potentially prolonging their studies.

5. Research approach: Differences in research methodologies and project scopes can affect the time needed for data collection, experimentation and analysis.

6. Academic culture: The US education system values a well-rounded education, including coursework and comprehensive exams. This can extend the time before full-time research begins. UK PhD programmes often prioritise independent research early on.

7. Part-time and work commitments: US PhD candidates might have more flexibility for part-time work or other commitments, which can affect research progress.

8. Dissertation requirements: US PhD programmes generally include a longer and more comprehensive dissertation, involving more chapters and a broader exploration of the research topic.

These variations in programme structures, funding models and academic cultures contribute to the differing completion times between the two countries.

What qualifications do you need for a PhD?

To be eligible for a PhD programme, certain educational qualifications are generally expected by universities. These qualifications serve as indicators of your readiness to engage in advanced research and contribute to the academic community.

First, an undergraduate or bachelor’s degree in a relevant field is typically the most common requirement. This degree provides you with a foundational understanding of the subject and introduces you to basic research methodologies. It serves as a starting point for your academic journey.

Do you need a master’s degree to get into a PhD programme?

In addition to an undergraduate degree, many PhD programmes also require candidates to hold postgraduate or master’s degrees, often in fields related to the intended PhD research. A master’s degree offers a deeper exploration of the subject matter and enhances your research skills. Possessing a master’s degree signifies a higher level of expertise and specialisation.

The combination of both undergraduate and postgraduate degrees demonstrates a solid academic background. This background is crucial before you engage in doctoral study because pursuing a PhD involves more than just knowledge; it requires advanced research abilities, critical thinking and the capacity to provide an original contribution and new insights into the chosen field of study.

While these qualifications are usually requested, there are exceptions. Some institutions offer direct-entry programmes that encompass bachelor’s, master’s and PhD degrees in a streamlined structure. This approach is often seen in scientific and engineering disciplines rather than humanities.

In exceptional cases, outstanding performance during undergraduate studies, coupled with a well-defined research proposal, might lead to direct entry into a PhD programme without requiring a master’s degree.

Admission requirements can vary between universities and programmes. Some institutions might have more flexible prerequisites, while others could have more stringent criteria. Make sure that you thoroughly research all admission requirements of the PhD programmes you’re interested in to ensure you provide the right information.

Are PhD entry requirements similar in other countries?

PhD entry requirements in Canada and Australia can be somewhat similar to those in the UK and the US, but there are also some differences. Just like in the UK and the US, having a bachelor’s degree followed by a master’s degree is a common way to qualify for a PhD in Canada and Australia. However, the exact rules can vary, such as how much research experience you need or the grades you should have.

In Canada and Australia, as in the UK and the US, international students usually need to show their English language skills through tests like IELTS or TOEFL. And, like in other places, you might need to give a research proposal to explain what you want to study for your PhD.

But remember, even though there are some similarities, each country has its own rules.

How much does it cost to study a PhD?

The cost of pursuing a PhD can vary significantly between international and home (domestic) students, and it depends on the country, university and programme you choose.

United Kingdom (UK)

Home students in the UK often pay lower tuition fees compared with international students. Home students might also have access to government funding or subsidised tuition rates.

International students typically pay higher tuition fees, which can vary widely depending on the university and programme. Fees can range from around £10,000 to £25,000 or more per year.

United States (US)

PhD programme costs in the US can be quite high, especially for international students. Public universities often have lower tuition rates for in-state residents compared with out-of-state residents and international students.

Private universities in the US generally have higher tuition fees, and international students might be charged higher rates than domestic students.

Canadian universities often charge higher tuition fees for international students compared with domestic students.

Some universities offer funding packages that include tuition waivers and stipends for both domestic and international doctoral students.

In Australia, domestic students (Australian citizens and permanent residents) usually pay lower tuition fees than international students.

International students in Australia might have higher tuition fees, and costs can vary based on the university and programme.

Apart from tuition fees, other aspects play a role in the overall financial consideration:

PhD studentship: Many universities offer PhD studentships that provide financial support to research students, covering both tuition fees and a stipend for living expenses.

Stipend and housing: Stipends are designed to cover living expenses. Stipend amounts can vary depending on the university and location. If you’re studying in London in the UK, stipends might be higher to account for the higher living costs in the city. Some universities also offer subsidised or affordable housing options for doctoral students.

Tuition and stipend packages: Some PhD programmes provide funding packages that include both tuition waivers and stipends. These packages are to help relieve the financial burden on students during their doctoral studies.

Research the financial support options provided by the universities you’re interested in to make an informed decision about the cost of your PhD journey.

What funding options are available for PhD candidates?

PhD candidates have various funding options available to support their studies and research journeys. Some of these options include:

PhD scholarships: Scholarships are a common form of financial aid for PhD candidates. They are awarded based on academic merit, research potential or other specific criteria. Scholarships can cover tuition fees and provide a stipend for living expenses.

Bursaries: Bursaries are another form of financial assistance offered to students, including PhD candidates, based on financial need. They can help cover tuition fees or provide additional financial support.

In the UK, specific funding options are available:

Regional consortium: Some regions have research consortiums that offer funding opportunities for doctoral candidates. These collaborations can provide financial support for research projects aligned with specific regional needs.

UK research institute: Research councils in the UK often offer stipends to PhD candidates. These stipends cover living expenses and support research work.

University-based studentship: Many UK universities offer studentships. You can read more about these above.

In the USA, there are also funding options available:

Research assistantships (RAs): Many universities offer research assistantships where PhD candidates work on research projects under the guidance of faculty members. In exchange, they receive stipends and often have their tuition waived.

Teaching assistantships (TA): Teaching assistantships involve assisting professors in teaching undergraduate courses. In return, PhD candidates receive stipends and sometimes tuition remission.

Fellowships: Fellowships are competitive awards that provide financial support for PhD candidates. They can come from universities, government agencies, private foundations and other institutions. Fellowships can cover tuition, provide stipends and offer research or travel funds.

Graduate assistantships: Graduate assistantships include a range of roles, from research and teaching to administrative support. These positions often come with stipends and sometimes include tuition benefits.

External grants and fellowships: PhD candidates can apply for grants and fellowships from external organisations and foundations that support research careers in specific fields. Examples include the National Science Foundation (NSF) and the Fulbright Programme.

Employer sponsorship: In some cases, employers might sponsor employees to pursue PhDs, especially if the research aligns with the company’s interests.

What does a PhD Involve?

How does a PhD work?

A PhD includes thorough academic research and significant contributions to your chosen field of study. The timeline for completing a PhD can significantly vary based on the country, college or university you attend and the specific subject you study.

The duration of a PhD programme can vary based on factors such as the institution’s requirements and the academic discipline you’re pursuing. For instance, the timeline for a PhD in a science-related field might differ from that of a humanities discipline.

UK PhD timeline example

Looking at a typical PhD degree in a London higher education institution, we can consider this example timeline.

In the initial year of your PhD, you’ll collaborate closely with your designated academic supervisor. This collaboration involves refining and solidifying your research proposal, which lays the foundation for your entire doctoral journey.

This is also the time to establish a comprehensive plan, complete with well-defined milestones and deadlines. A crucial aspect of this year is conducting an extensive literature review, immersing yourself in existing academic works to understand the landscape of your chosen research area. It’s important to make sure that your research idea is original and distinct from prior studies.

As you begin the second year, you’ll actively collect data and gather information related to your research topic. Simultaneously, you’ll initiate the process of crafting your thesis. This involves combining your research findings and analysis into sections of your thesis document.

This is also the phase where you might have opportunities to share your research insights at academic meetings, conferences or workshops. Depending on the programme, you might even engage in teaching activities. Some PhD candidates also begin contributing to academic journals or books, showcasing their findings to a broader audience.

The third year of a PhD programme often marks the final stage of your research efforts. This is when you dedicate substantial time to writing and finalising your complete thesis. Once your thesis is completed to the highest standard, you’ll submit it for thorough evaluation.

A significant milestone in the third year is the viva voce, an oral examination where you’ll defend your thesis before a panel of experts in your field. The viva voce is an opportunity to showcase your deep understanding of your research and defend your findings.

Why should you do a PhD?

For many people, acquiring a doctorate degree is the pinnacle of academic achievement, the culmination of years of commitment to higher education.

However, the act of pursuing a PhD can be a complex, frustrating, expensive and time-consuming exercise. But with the right preparation, some sound advice and a thorough understanding of the task at hand, your years as a doctoral student can be some of the most rewarding of your life. 

People choose to work towards a doctorate for many reasons. If you are looking to pursue an academic position, such as university lecturer or researcher, then a PhD is usually required.

Many people obtain a PhD as part of a partnership with an employer, particularly in scientific fields such as engineering, where their research can prove useful for companies.

In some cases, however, PhDs are simply down to an individual’s love of a subject and their desire to learn more about their field.

What are some benefits of studying a PhD?

Pursuing a PhD can have many benefits that extend beyond academic achievement, encompassing personal growth, professional advancement and meaningful contributions to knowledge.

One of the most notable benefits of a PhD is the potential for tenure in academia. Attaining tenure provides a level of job security that allows you to delve into long-term research projects and make enduring contributions to your field. It signifies a stage where you can explore innovative ideas and pursue in-depth research, fostering your academic legacy.

While not obligatory, the opportunity to collaborate on research projects with your supervisor is another valuable aspect of a PhD pursuit. These collaborations might even come with financial compensation, offering real-world experience, skill development and practical applications of your research. Engaging in such collaborations can enrich your research portfolio and refine your research methodologies.

A pivotal aspect of a PhD journey is the chance to publish your original research findings. By disseminating your work in academic journals or presenting it at conferences, you contribute to the expansion of knowledge within your field. These publications establish your expertise and reputation among peers and researchers worldwide, leaving a lasting impact.

The pursuit of a PhD can provide a unique platform to build a diverse network of colleagues, mentors and collaborators. Engaging with fellow researchers, attending conferences and participating in academic events offer opportunities to make valuable connections. This network can lead to collaborations, expose you to a spectrum of perspectives and pave the way for future research endeavours.

What is a PhD thesis? And what is a PhD viva?

A PhD thesis will be produced with help from an academic supervisor, usually one with expertise in your particular field of study. This thesis is the backbone of a PhD, and is the candidate’s opportunity to communicate their original research to others in their field (and a wider audience).  PhD students also have to explain their research project and defend their thesis in front of a panel of academics. This part of the process is often the most challenging, since writing a thesis is a major part of many undergraduate or master’s degrees, but having to defend it from criticism in real time is arguably more daunting.  This questioning is known as a “viva”, and examiners will pay particular attention to a PhD’s weaknesses either in terms of methodology or findings. Candidates will be expected to have a strong understanding of their subject areas and be able to justify specific elements of their research quickly and succinctly.

In rare cases, students going for a PhD may instead be awarded an MPhil if the academic standard of their work is not considered fully up to par but still strong enough to be deserving of a qualification.

Can you do a PhD part time? 

Many PhD and MPhil candidates choose to pursue their qualification part time, in order to allow time to work and earn while studying. This is especially true of older students, who might be returning to academia after working for a few years. 

When applying, you should always speak to the admissions team at your university to ensure this is possible and then continue to work with your supervisor to balance all your commitments. 

Can I do a PhD through distance learning?

This is something else that you will need to check with your university. Some institutions offer this option, depending on the nature of your research. 

You will need to be clear how many times you will need to travel to your university to meet with your supervisor throughout your PhD. 

Your PhD supervisor

Choosing the right PhD supervisor is essential if you want to get the most out of your PhD. Do your research into the faculty at the institution and ensure that you meet with your proposed supervisor (either virtually or in person) before fully committing. 

You need to know that not only do they have the right expertise and understanding of your research but also that your personalities won’t clash throughout your PhD. 

Remember, to complete your PhD, you will need a strong support network in place, and your supervisor is a key part of that network. 

Coping with PhD stress

If you do decide to embark on a doctorate, you may well encounter stress and anxiety. The work involved is often carried out alone, the hours can be long and many students can suffer from the pressure they feel is on their shoulders.

Ensuring that you check in regularly with your emotions and your workload is crucial to avoid burnout. If you have other commitments, such as a job or a family, then learning to balance these can feel overwhelming at times. 

Give yourself regular breaks, speak to your supervisor and ensure that you know what university resources and support systems are available to you in case you need to access them. 

Post-doctorate: what happens after you finish your PhD?

Many PhD graduates pursue a career in academia, while others will work in industry. Some might take time out, if they can afford to, to recover from the efforts of PhD study.

Whatever you choose to do, undertaking a PhD is a huge task that can open up a range of doors professionally. Just remember to take some time out to celebrate your achievement. 

How does a PhD affect salary and earning potential?

How much does a professor with a PhD make a year?

Professors with PhDs can earn different amounts depending on where they work and their experience. In the UK, a professor might make around £50,000 to £100,000 or more each year. In the US, it's between about $60,000 and $200,000 or even higher. The exact salary depends on things like the place they work, if they have tenure, and what they teach.

How much does a PhD add to salary?

Having a PhD can make your salary higher than if you had a lower degree. But exactly how much more you earn can change. On average, people with PhDs earn more than those with bachelor’s or master’s degrees. The increase in salary is influenced by many things, such as the job you do, where you work and what field you’re in.

In fields such as research, healthcare, technology and finance, your knowledge and skills from your PhD can potentially help you secure a higher salary position.

In the end, having a PhD can boost your earning potential and open doors to well-paying jobs, including professorships and special roles in different areas. But the exact effect on your salary is influenced by many things, so ensure you weigh the cost against the benefit.

How to choose a PhD programme?

Choosing a PhD programme involves defining your research interest, researching supervisors and programme reputation, evaluating funding options, reviewing programme structure, considering available resources, assessing networking opportunities, factoring in location and career outcomes, visiting the campus if possible and trusting your instincts.

How can I find available PhD programmes?

You can find available PhD programmes by visiting university websites, using online directories such as “FindAPhD”, checking professional associations, networking with professors and students, following universities on social media, attending career fairs and conferences, contacting universities directly and exploring research institutes’ websites.

RIT graduate pursues Ph.D. across time zones

Nastaran Nagshineh is shown with other faculty in a small room where she defended her thesis.

Nastaran Nagshineh, center, defended her Ph.D. thesis at RIT in April. Faculty from RIT’s Rochester and Dubai campuses served on her thesis committee and include, from left to right, Kathleen Lamkin-Kennard, Steven Weinstein, Nathaniel Barlow, and David Kofke (a professor at the University at Buffalo). Mohamed Samaha participated remotely and appears on the video screen behind the group and alongside Nagshineh’s picture.

Nastaran Nagshineh is one of the first Ph.D. candidates to bridge RIT’s Rochester and Dubai campuses. Her accomplishment creates a path for future students at the university’s international campuses.

Nagshineh completed her Ph.D. in mathematical modeling while working full time as a mathematics lecturer at RIT Dubai in the United Arab Emirates, teaching as many as five classes a semester. She described her Ph.D. journey as “an exercise in perseverance” due to competing demands and long days. Rochester is eight hours behind Dubai, and the time difference meant many late-night classes and meetings.

“I saw this collaboration as an opportunity, rather than as a challenge, because my primary adviser, Dr. Steven Weinstein (RIT professor of chemical engineering), and my co-adviser, Dr. Mohamed Samaha (RIT Dubai associate professor of mechanical engineering), both have the same area of research interest,” she said. “They both worked toward my success.”

Nagshineh is one of 67 RIT Ph.D. students who defended their thesis this academic year and who will earn their doctorate. RIT awarded 63 Ph.D. degrees in 2023.

In 2020-2021, RIT’s Graduate School met and surpassed the university’s goal of conferring 50 Ph.D. degrees during an academic year. That number will continue to grow as students cycle through the seven new Ph.D. programs that RIT has added since 2017, said Diane Slusarski , dean of RIT’s Graduate School.

Meeting these goals puts RIT on a path toward achieving an “R1,” or research-intensive designation, from the Carnegie Classification of Institutions of Higher Learning. RIT is currently ranked as an R2 institution . Many factors go into changing a university’s status, including research investment and maintaining a three-year average of 70 Ph.D. degrees awarded per year, according to Slusarski.

“We have met the goals of the strategic plan, and now we look forward to contributing to the research innovation in the future,” Slusarski said. “We want to help the new programs thrive and win national research awards.”

RIT’s emphasis on high-level research is seen in Nagshineh’s Ph.D. work. She applies mathematical modeling to the field of fluid dynamics. Her research has been published in top-tier journals and has gained notice, said Weinstein, her thesis adviser.

Weinstein describes Nagshineh’s accomplishments as “a testament to a fantastic work ethic and commitment” and is inspirational to younger students at Rochester and Dubai.

“The collaboration between RIT Dubai/Rochester has continued,” he said. “Another paper was submitted a few weeks ago with Mohamed Samaha and Nate Barlow (RIT associate professor in the School of Mathematics and Statistics) as co-authors, as well as Cade Reinberger, a younger Ph.D. student in my research group.”

Mathematical modeling is one of RIT’s newer Ph.D. degree programs, and Nagshineh is among its earliest graduates. The program has doubled in size since it began accepting students in 2017, Slusarski said. This past fall, the mathematical modeling program had 35 students, with two graduating this year.

Altogether, RIT has 13 Ph.D. degree programs currently enrolling 438 students, with computing and information sciences accounting for the largest with 117 students. RIT’s other Ph.D. programs include astrophysical sciences and technology , biomedical and chemical engineering , business administration , color science , electrical and computer engineering, imaging science , mechanical and industrial engineering , microsystems engineering , and sustainability .

New programs in cognitive science and physics will launch in the fall.

The growth in RIT graduate education—with more than 3,000 master’s and doctoral students—reflects a demographic change in the student population, Slusarski said. “We have a higher percentage of women in the graduate programs than we have for RIT undergraduate programs.”

RIT’s graduate programs enroll 42 percent women, according to Christie Leone , assistant dean for the Graduate School.

Nagshineh, who also holds an MS in electrical engineering from RIT Dubai, welcomes her role as a mentor to other women students on both campuses.

“As a young woman in an Arabic country, the power of women is often underestimated and undervalued, and I hope to serve as a role model to female students, especially those that question their path,” Nagshineh said.

She plans to continue in her career as a professor and a researcher. “I would like to pursue a research program where I can advise my own students and teach them more deeply.”
