How to write a dissertation proposal
What a dissertation proposal must contain, how long each section should be, and how supervisors decide whether to approve it.

A dissertation proposal is not a summary of what you hope to find. It is an argument that your project is worth doing, feasible in the time you have, and ethically sound.
Supervisors approve proposals that answer three questions quickly: what exactly are you asking, how will you answer it, and can you finish it?
What a proposal must contain
Most UK proposals run to 1,500-3,000 words, though some departments ask for as little as 1,000. The sections are consistent even when the length is not.
- Working title: the research question, phrased as a title.
- Background and rationale: why this problem, why now.
- Preliminary literature: five to fifteen key sources and the gap they leave.
- Research question, aim and objectives: one question, two to four objectives.
- Methodology: design, participants or data, sampling, collection and analysis.
- Ethics: risks, consent, data protection, approval route.
- Timeline: milestones against your actual submission date.
- References: properly formatted in your required style.
Write the question before anything else
Everything in the proposal is justified against the research question. If you write the background first, you will end up justifying a topic rather than a question, and the methodology section will not connect.
Make the methodology specific
'Qualitative interviews' is not a methodology. 'Twelve semi-structured interviews with early-career teachers in two Midlands secondary schools, analysed using reflexive thematic analysis' is. Specificity is what convinces a supervisor the project is real.
Show the project is feasible
Name your access route to participants or data, and give a timeline with dated milestones. A proposal that assumes access to a hard-to-reach population without evidence is the most common reason for a rejection or a request to revise.
Common mistakes
- Promising findings before collecting any data.
- Listing methods without justifying them.
- Ignoring ethics approval timelines, which can take weeks.
- Writing a topic overview instead of a researchable question.
Try this: The supervisor's three questions
- Write your research question in one sentence.
- In two sentences, say how you will answer it and with what evidence.
- In one sentence, say why it can be finished by your deadline.
- If any answer needs more than the allotted sentences, the proposal is not ready.

Build your proposal planStudents also ask
- What should a dissertation proposal include?
- A working title, background and rationale, preliminary literature and the gap it leaves, your research question with aim and objectives, a specific methodology, ethics considerations, a dated timeline and correctly formatted references.
- How long should a dissertation proposal be?
- Most UK departments ask for 1,500-3,000 words, though some require as little as 1,000. Always follow your own handbook, because the required sections vary more than the length does.
- Why do supervisors reject dissertation proposals?
- Usually because the question is a topic rather than a researchable question, the methodology is named but not justified, or feasibility is unproven - especially access to participants and the time ethics approval will take.
