5 routes to getting a Doctorate

While most of those studying for a PhD take the PhD by thesis pathway, there are five viable routes to achieving a Doctorate degree

PhD by thesis

This is the most common means of getting a Doctorate degree. Over the three or four years of research at university, your PhD supervisor will support you as you aim to produce a thesis based on your research proposal .

A thesis is typically 60,000-90,000 words in length - although this can vary between institutions. For instance, the University of Glasgow's College of Social Sciences expects a thesis to be 70,000-100,000 words including references, bibliography and appendices, while the University of Cambridge has set an upper limit of 80,000 words.

Once completed, you'll need to defend your PhD thesis in front of a panel of examiners during your viva voce .

PhD by publication

This route involves submitting previously published work - such as books, book chapters and journal articles, which together form a coherent body of work and show evidence of an original contribution to a particular field of study.

It's often taken by mid-career academics that haven't had the opportunity to undertake a standard Doctorate degree.

Generally, a minimum of five to eight published pieces are required, but this varies between institutions and depends on their length. The published work will be assessed to the same rigorous standards as a traditional PhD by thesis.

You must also provide a written supporting statement, which can range from 5,000 to 20,000 words, and present your work to an academic committee. A supervisor will assist you with selecting which publications to submit and with the supporting statement.

Some universities accept only their own graduates for a PhD by publication, while others restrict this route to their academic staff. In general, you should have graduated from your first degree at least seven years ago to be eligible.

For example, The University of Manchester has published its own Guidance for the PhD By Published Work , with eligibility only extending to current members of staff.

Professional Doctorate

Geared primarily towards current professionals in vocational sectors such as healthcare , teaching and education , and engineering and manufacturing , this type of Doctorate degree includes a significant taught component and a smaller research project.

Professional Doctorates are often taken on a part-time basis and can last between two and eight years. Like their standard PhD counterparts, they usually begin in October or January.

While you won't typically be looking to get an academic job , your research is expected to contribute to theory as well as professional practice. Projects often revolve around a real-life issue that affects your employer.

Several professional Doctorates, such as the Doctorate in Clinical Psychology (DClinPsy), are accredited by a professional body - for instance, the Health & Care Professions Council (HCPC) and The British Psychological Society (BPS) - and may also lead to a professional qualification .

Common titles for graduates of professional Doctorate degrees include:

• Doctor of Business Administration (DBA)
• Doctor of Education (EdD)
• Doctor of Engineering (EngD)
• Doctor of Medicine (MD).

Unlike many professional Doctorates, the EngD is typically offered as a full-time course and is aimed at young engineering graduates with little or no professional experience.

Integrated PhD

This four-year qualification, also known as the New Route PhD, involves studying a one-year research Masters degree (MRes) before progressing onto a three-year PhD.

Offered by a select number of universities across the UK, integrated PhDs are supported by the government and the British Council through UK Research and Innovation (UKRI) . Visit Research Council funding for further information on research and funding for different types of PhD.

The integrated PhD involves a combination of taught materials, practical experience and advanced research. This allows you to learn subject-specific methodologies, while building the transferable skills that will enable you to become a leader in your chosen profession.

Institutions can also develop personalised integrated PhD programmes to meet each student's needs. For example, universities may offer you the opportunity to gain a postgraduate certificate (PGCert) in Learning and Teaching in Higher Education - perfect if you're considering a career as a higher education lecturer .

As PhDs are based primarily on independent research rather than time spent in lectures and seminars, distance learning has always been a viable route for many Doctoral students.

PhDs by distance learning offered by course providers such as The Open University are therefore a good option to consider if you've got family or work commitments or are an international student - as this gives you the chance to undertake Doctoral research without having to live close to your chosen institution. It's also a suitable mode of study if your subject requires you to be based in a specific location away from the university.

For the most part, you'll be in touch with your supervisor by phone, email or Skype/Zoom. You'll need to bear in mind that even if you opt for this form of research, you'll generally still need to attend university for one or two weeks of each academic year for meetings and to receive research skills training. Your final examination may be undertaken either face-to-face or virtually.

With online PhDs, you can usually register as a full or part-time student. The level of fees you pay varies between institutions - some charge the same as for a standard PhD while others offer a reduced rate.

Check that any funding you plan to apply for is available to distance learning students, as this isn't always the case.

A PhD (Doctor of Philosophy) is the most common type of doctoral degree and the highest level of academic qualification you can achieve. 

It normally takes between three and four years of full-time work to complete. It is also possible to undertake a PhD part time, over five to six years.

The main activity of a PhD is to carry out an original research project under the direction of one or more supervisors, to be written up as a thesis.

Different routes to achieving a PhD

There are a number of ways to achieving a PhD at Imperial:

• by undertaking a course of study based on your own research proposal
• by joining a research project that comes with funding attached (known as a studentship)
• by combining it with Master's study in an integrated route that typically lasts four years

Pursuing your own research idea

To search for PhD opportunities based on your own research proposal you first need to identify a research group within Imperial whose area of expertise best matches your idea.

Use the links below to search the different PhD opportunities within our academic departments, centres and institutes. This includes information about current studentships and often guidance on finding a supervisor.

8 big differences between the US and UK PhD experience

And one important similarity.

And one important similarity.

11 March 2020

Malte Mueller/Getty

In 2019, I took a risk by moving halfway around the world as a postdoctoral researcher in molecular evolution.

Since then, I’ve been struck by how different the grad school experience is here at the University of Chicago in the US, compared with my time at the University College London in the UK, where I completed my PhD in 2017.

Here’s what I’ve noticed:

1. UK grad school interviews are shorter and more lab-specific

In the UK, you’re likely to apply directly to a lab for an advertised project or one that you develop with your supervisor.

In the US, the application process is more centralized. You usually apply to a school instead of a lab. Some programs even require you to take a standardized Graduate Entry Program test, though this seems to be on the decline .

Grad school interviews in the US tend to be longer. They can involve a series of interviews, tours, and faculty events over a number of days.

2. In the US, a work-life balance is harder to achieve

I’ve been surprised by how all-encompassing a US doctorate can be. Even after the first year of teaching, the number of seminars, journal clubs, and university-related activities make the US PhD experience very grad school-centric.

I was fortunate during my UK-based PhD to approach it more like a full-time job than a continuation of my masters year. There were intense periods that required late nights in the lab, but I had time to pursue other interests , which provided some balance and made me more productive at work.

Of course, it’s difficult to generalize about working patterns. Demanding schedules are not wholly dictated by the country you’re studying in. A recent study found that 76% of surveyed grad students spent more than 41 hours a week on their project.

3. It takes longer to complete a PhD in the US

Probably the best-known difference is the time it takes to complete a PhD.

UK PhD programs tend towards three years in length, although it’s increasingly getting closer to four years – a trend that might soon be reflected in funding arrangements .

It’s a different story in the US, where, according to the Survey of Earned Doctorates , students take an average of 5.7 years to graduate.

4. UK PhD fees tend to be lower

Fees err on the more expensive side in the US, as they do for undergraduate degrees – although this isn’t always true for international students.

US PhD fees, coupled with the longer study time, means that the costs associated with grad school are generally higher than in the UK, even before living costs are considered.

If you have a funding body attached to your project, it will likely pay your tuition fees as part of its finance package. But this flags a major difference between the two countries: funding and scholarships.

5. Many US students need to apply for their own funding

From my understanding, most advertised science-based PhD projects in the UK are attached to funding, which covers tuition fees, bench costs, and living expenses. The tax-free PhD stipend set by all UK Research Councils is £15,285 (approximately US$20,000), although other funding bodies pay more.

In the US, there is no national funding level – your level of financial support will be dictated by your school or lab. This means there is generally much more encouragement for US PhD students to apply for their own funding than there is in the UK.

This is good experience for a future scientific career, but if you have to work additional hours to supplement scholarships, you’ll ultimately end up with less time for your project.

6. US PhD programs are more structured

This is particularly true in the first year for US PhDs, which includes lectures, exams, and lab rotations. Only at the end of the first year, after passing your qualifying exam, do you have the opportunity to pick the lab you’re going to pursue your PhD research in.

In the UK, I started in the lab that I spent the duration of my studies in. This meant no structured classes or rotations in my first year, and I began my own research right away.

PhDs that are run through a Doctoral Training Centre (DTC) – centres that manage the Research Council-funded PhD degrees – are increasingly popular in the UK, and include classes and rotations during the first year, but often without the frequent exams and coursework that characterize grad school in the US.

7. There is more focus on defending your thesis in the UK

Writing my thesis was the final hurdle of my UK PhD experience. It gave me the opportunity to document my ideas, successes (and failures), and the context of my project. I defended my thesis in a closed session with two examiners: one internal to my institution, and one external.

From what I’ve seen, finishing a doctorate in the US is less focused on a thesis. Instead, your committee determines that you have completed sufficient work and skill attainment to warrant your defense. Only then can you write your thesis, and defend it in a public session.

In the UK, it’s unlikely you’ll know your examiners well, but a US PhD defense is assessed by the same thesis committee that have known you for the duration of your studies.

8. Teaching is an added bonus in the UK

My UK PhD funding set no teaching requirements: instead, I was free to teach labs and mark coursework at the discretion of my supervisor. And I was paid for any teaching hours I did.

Teaching requirements in the US vary from school to school. For some students, working as a teaching assistant is necessary to pay fees and living expenses – particularly if you don’t have comprehensive funding.

There might also be minimum teaching requirements for the duration of your PhD in the US. In this respect, the time commitment and financial compensation of teaching is very institution-specific.

One important similarity: The lab you join will determine your experience

Despite the differences in structure and requirements between UK and US PhDs, one thing that is common to them all is that, ultimately, your PhD is going to be shaped by the lab you decide to join.

If have a positive working environment and appropriate guidance and support from your supervisor, and you’re interested in and motivated by your thesis topic, then your grad school experience will likely be rewarding.

And that’s true regardless of the country you’re studying in.

The ESRC invests heavily in PhD studentships to cultivate the next generation of social scientists. Despite only funding a minority of UK social science PhDs, the ESRC has considerable influence over the UK social science doctoral agenda. It has been more than ten years since the ESRC last conducted a review of its doctoral training. During that time, demand for challenge-led, inter-disciplinary research and evaluation, including the use of digital methods and ‘big data’ has increased. It is timely, therefore, to re-examine the social science doctoral offer, to identify its strengths as well as areas where it could be improved.
