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, with both full-time and part-time options available
PhD by thesis
This is the most common means of getting a Doctorate. 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 to 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 .
Doctorate 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.
The PhD by publication route is 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 typically ranges from 5,000 to 15,000 words.
For instance, the University of Westminster asks for a commentary of 5,000 words (science and technology subjects) or 10,000 words (arts, social sciences and humanities). On the other hand, Queen Margaret University Edinburgh requires 12,000 to 15,000 words on the rationale and theoretical context for the portfolio of published work.
The work will then be presented to an academic committee. A supervisor will assist you with selecting which publications to submit, as well as guidance on 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
This type of Doctorate includes a significant taught component and a smaller research project, and is geared primarily towards current professionals in vocational sectors such as:
- engineering and manufacturing
- teaching and education .
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 .
Online/distance learning PhD
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 exam 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.

How to apply for a phd.
Application rules and methods vary for each university. The number of courses that you can apply for in a year will vary. For example, at the University of Sussex , you can apply for up to three postgraduate courses per year using the postgraduate application system.
If you are applying for more than one degree, you must submit a research proposal/statement specific to each area of study you apply for.
You can also apply to different universities to improve your chances of being accepted to a PhD course of your choosing.
What qualifications do I need?
Each PhD will have specific entry requirements and you will also need to meet a university’s general entry requirements. This may be an upper second-class undergraduate honours degree (2:1) or an equivalent international qualification. For some PhDs you may need a master’s qualification, and you may be asked to attend an interview.
International students may also be required to prove language proficiency. This will vary across institutions so do check what level universities expect before starting your application.
Applicants should always check the specific entry requirements in a university’s online prospectus before making an application.
When should I start applying?
This will depend on when your term start date is. Most research degrees will start in September but some courses offer additional entry points in January or May.
You can apply all year round for research degrees starting in September, January and May, and the deadlines for applying are usually one month before the course start date for UK applicants, and three months before for international applicants.
If you’re applying for funding from an external organisation you’ll need to be aware that they may have different deadlines for the funding application. So give yourself plenty of time to research your funding options, and ensure you know how long the application process takes.
Many universities offer a number of funded PhD opportunities and PhD scholarships for UK and international students, and it’s always worth investigating funding routes such as research councils and other organisations, both in the UK and overseas.
In some cases, it may be possible to study a PhD by distance which means you’ll be able to learn online and have virtual meetings with your supervisor.
If this is something you would be interested in doing you should check before applying whether your university can accommodate this option.

How should I look for a supervisor?
Usually if you are applying for a funded project, or to a research centre or group, you will normally be asked to provide a statement explaining your suitability for working in that area, and if successful you will be allocated a supervisor.
If you wish to propose your own area of research, you need to decide on a research topic, and you will be expected to write a research proposal. In some cases you may only be required to provide a summary of academic interests and this can be used to match you to a researcher that suits you.
If you are proposing your own research topic, there may be a research database at your university that you can search, or your university will match you with a supervisor during the assessment of your application. It may be possible to request supervision by a particular member of faculty – this will be considered but not all requests can be accommodated.
If you do find a potential supervisor who matches your research area, check their online profile for indications of their doctoral supervision capacity. If they are open to doctoral applications, you can contact them directly to check their availability for supervising you.
It is a good idea to draw up a shortlist of two to three potential supervisors, and take an in-depth look into their research history. You can also find out more about your potential supervisors by looking in the reference sections of academic textbooks and searching for articles in research databases and academic blogs.
When you contact your potential supervisor, it is important to tell them something interesting about yourself, and explain your research interests and how you feel your research proposal matches their expertise.
How do I write a research proposal?
If you are proposing your own research you will need to write a strong proposal that formulates a precise, interesting research question, and establishes the relevance and value of the proposed research question in the context of current academic thinking.
You’ll need to make sure your proposal describes the data or source material your research requires, and outlines a clear and practical methodology that enables you to answer the research question and that states clearly what you hope to discover at the end of your research, and what new areas it might open up.
The precise content and structure of your research proposal will depend on your subject area, and the University of Sussex has some helpful resources on our website to guide you through the process.
How long does the application process take?
Completing an application and writing a research proposal may take some time and should not be left until just before the application deadline.
It’s not easy to give a definite idea of how long it takes to hear if your application has been successful, as it will depend on when the application is made and the nature of the specific PhD, and you would need to meet any conditions contained within the offer before you can start the PhD.
What are the associated costs?
There won’t typically be an application fee for PhDs but there are tuition fees. If a university does charge application fees they will usually be between £50-£100.
The tuition fees for students studying in the UK are set by UK Research and Innovation . Fees for international students are £18,975 for non-lab-based subjects, and £22,975 for lab-based subjects per year.
You’ll also need to factor in living costs, but there are a number of funding routes you can apply for to help with this. As well as PhD scholarships and funded research projects there are research council awards, PhD loans for those eligible, and various organisations to which international students can apply for funding, such as The Gen Foundation and Open Society Foundations.
It’s important to be aware of the costs involved, but it’s also worth remembering that the educational, career and personal benefits of PhD study can be worth it.
