Quick answer

A research proposal is a plan for a study you have not done yet. Most proposals have 7 parts: title, introduction/background, literature review, research questions or aims, methods, timeline and budget, and references. Below is a short annotated example, a copyable template, and real published study protocols you can download as free PDFs.

What Is a Research Proposal?

A research proposal is a document that explains what you want to study, why it matters, and how you will do it, before you collect any data. Supervisors, admission committees, ethics boards and funders read it to decide one thing: is this study worth doing, and can this person actually do it?

Updated October 2026.

You will usually write a research proposal for:

A PhD application (often 1,500–3,000 words) so a department can judge your idea and match you to a supervisor
A masters dissertation or thesis (often 1,000–2,500 words) before your supervisor approves the topic
An undergraduate final-year project (often 500–1,500 words)
A grant or ethics application, where the format is set by the funder or committee

A proposal is written in the future tense ("we will recruit…") because the study has not happened. A research paper is written in the past tense because it reports what was done. If you want to see what the finished product looks like, see our annotated research paper example.

Research Proposal Format: The Standard Structure

Universities and funders use slightly different headings, but almost every research proposal format contains the same building blocks. The table below shows each section, what to write in it, and a typical length for a masters or PhD proposal of about 2,000–3,000 words. Always check your university or funder guidelines first: if they give a word limit or headings, follow them exactly.

Research proposal structure: section, content and typical length
Feature	What to write	Typical length
Title	Specific: topic, population, outcome or method	10–20 words
Abstract / summary	Problem, aim, method and expected contribution in one paragraph	150–300 words
Introduction / background	The problem, why it matters, and the context	300–500 words
Literature review	What is already known, key studies, and the gap your study fills	500–1,000 words
Research questions / aims / hypotheses	1 main question plus 2–4 objectives; hypotheses if quantitative	100–200 words
Methodology	Design, participants, sampling, data collection, analysis, ethics	600–1,000 words
Expected results and significance	What you expect to find and who will benefit	150–300 words
Timeline (and budget if asked)	Gantt chart or month-by-month plan; costs for funders	Table, ½ page
References	Every source cited, in one style (APA, Harvard, Vancouver)	15–40 sources

Research Proposal Example (Annotated)

Below is a short sample research proposal on a simple topic: the effect of sleep on student exam performance. It is an illustrative example written for this guide, not a real study. The citations are described in words rather than given as real references, so do not copy them into your own work. Each part is followed by a note explaining why it works.

The example is about 900 words, which suits an undergraduate project or the core of a masters proposal. A PhD proposal would expand each part, especially the literature review and methods.

1. Title and Abstract

Title: Sleep Duration Before Exams and Exam Performance in First-Year University Students: A Prospective Cohort Study

Abstract: Many university students sleep less than the recommended 7–9 hours, especially during exam periods. Laboratory studies show that sleep loss harms memory and attention, but fewer studies have followed real students through real exams. This study will measure the sleep of 200 first-year students using a sleep diary and a wrist-worn activity tracker for the 14 nights before end-of-semester exams, and link it to their exam scores. We will test whether students who sleep less score lower, after adjusting for prior grades, study hours and stress. The results will help universities decide whether sleep education should be part of exam preparation support.

For more models, compare these abstract examples for research papers.

2. Introduction and Background

Sleep supports learning in two ways: it helps the brain consolidate what was studied during the day, and it restores the attention needed to recall that information in an exam. Surveys in many countries report that a large share of university students sleep less than seven hours on weeknights, and that sleep gets shorter during exam weeks as students study late.

For universities, this matters because poor exam results lead to repeated courses, lower confidence and dropout. If shorter sleep before exams is linked to lower scores, a simple and cheap intervention (sleep education) could help.

3. Literature Review and Research Gap

Experimental studies in sleep laboratories show that one night of sleep deprivation reduces performance on memory tests. Observational studies of students have found associations between self-reported sleep quality and grade point average. However, most of these studies (a) use a single questionnaire about "usual" sleep rather than measuring sleep in the days before a specific exam, (b) rely only on self-report, and (c) do not adjust for prior academic ability, which could explain both poor sleep and low grades.

The gap: we do not know whether objectively measured sleep in the two weeks before exams predicts exam scores once prior grades and study time are taken into account.

4. Research Questions, Aims and Hypotheses

Main research question: Is average nightly sleep duration in the 14 nights before end-of-semester exams associated with exam scores in first-year university students?

Objectives:

To measure sleep duration and timing in the 14 nights before exams using an activity tracker and a sleep diary.
To estimate the association between average sleep duration and mean exam score, adjusting for prior grades, study hours and perceived stress.
To explore whether sleep on the night immediately before an exam matters more than average sleep across the two weeks.

Hypothesis: Students who sleep less than 7 hours on average will have lower adjusted exam scores than students who sleep 7 hours or more.

5. Methodology

Design: prospective cohort study.

Participants: 200 first-year undergraduate students at one university, recruited by email and lecture announcements. Inclusion: aged 18–25, enrolled in at least three exams. Exclusion: diagnosed sleep disorder or night-shift work. A sample of 200 gives adequate power to detect a moderate association, allowing for 15% dropout (sample size calculation to be shown in an appendix).

Data collection: participants will wear a wrist activity tracker and complete a short daily sleep diary for 14 nights before exams. Baseline questionnaires will record prior grades, weekly study hours and perceived stress using a validated stress scale. Exam scores will be obtained from university records with written consent.

Analysis: multiple linear regression with mean exam score as the outcome and average sleep duration as the main predictor, adjusted for prior grades, study hours and stress. Objective 3 will be tested with a mixed-effects model using each exam as a separate observation.

Ethics: approval will be sought from the university research ethics committee. Data will be anonymised and stored on a password-protected university server. Participation will not affect grades.

6. Expected Results, Significance and Timeline

Expected results: we expect shorter sleep to be associated with lower exam scores, even after adjustment. If so, the findings will support adding sleep guidance to university exam preparation and wellbeing programmes. If no association is found, this is also useful: it suggests that support should focus on other factors such as study methods or stress.

Timeline (9 months):

Months 1–2: ethics approval, literature review update, buy trackers
Months 3–4: recruitment and baseline questionnaires
Month 5: 14-night sleep monitoring and exams
Months 6–7: data cleaning and analysis
Months 8–9: writing the dissertation and presenting results

Budget (if required): 50 activity trackers reused across four groups of participants; small vouchers for participants who complete the diary.

7. References

In a real proposal, every study mentioned in the background and literature review is listed here in one citation style (for example APA 7 or Harvard). Aim for 15–40 sources for a masters or PhD proposal, mostly peer-reviewed and mostly from the last 10 years, plus a few classic or foundational studies.

To find those sources quickly and get the citation in the right style, see how to find literature for your proposal below.

Research Proposal Template (Copy and Fill In)

Copy this research proposal template into your document and replace each line with your own text. It works for a masters or PhD research proposal and for most undergraduate projects. Remove any heading your guidelines do not ask for.

Title: [Exposure or intervention] and [outcome] in [population]: a [study design]
Abstract (150–300 words): Problem. Gap. Aim. Method. Expected contribution.
Introduction / background: What is the problem? Who does it affect? Why does it matter now?
Literature review: Theme 1 (what is known). Theme 2 (what is known). Weaknesses or contradictions in existing studies. The gap your study fills.
Research question: One sentence ending in a question mark.
Objectives: 2–4 numbered objectives that each start with a verb (to measure, to compare, to explore).
Hypotheses (quantitative only): What you expect, stated so it can be tested.
Methodology: Design. Setting. Participants and sampling (with inclusion and exclusion criteria). Sample size and why. Data collection tools. Analysis plan for each objective. Ethics and data management.
Expected results and significance: What you expect and who benefits (practice, policy, theory).
Limitations: 2–3 honest limitations and how you will reduce them.
Timeline: Month-by-month or a Gantt chart.
Budget (if required): Equipment, travel, participant payments, software.
References: One style, 15–40 sources.

PhD vs masters research proposal: a PhD proposal is usually longer (2,000–3,500 words), needs a stronger case for originality, and often covers three years with several linked studies. A masters proposal is shorter, covers one study, and must be feasible in a few months. Undergraduate proposals focus on a clear question and a simple, safe method.

For the next step after approval, see how to write a research paper. If your proposal becomes a thesis, see these thesis and dissertation examples.

Pick a narrow topic — One population, one outcome, one setting
Read the literature — Find 15–40 key sources and note the gap
Write the question — One main question plus 2–4 objectives
Plan the methods — Design, sample, tools, analysis, ethics
Add timeline — Realistic months, budget if asked
Check and cite — Follow guidelines, one citation style

Research Proposal Example PDFs: Real Published Study Protocols

Most real research proposals are private, but many researchers publish their plan as a study protocol in open-access journals such as BMJ Open and JMIR Research Protocols. A study protocol is a research proposal that has been peer reviewed and published before the results are known. It has the same parts: background, aims, methods, analysis plan, ethics and dissemination.

The examples below are genuine open-access protocols, all free to download as PDFs from PubMed Central. They cover different designs (cross-sectional survey, randomised trial, cohort, feasibility study), so pick the one that matches your own study. Several are about sleep and students, so you can compare them with the annotated example above.

Are they sleeping? A Canadian cross-sectional study exploring sleep quality among medical students: a study protocol — Tsai, Z., Charlesworth, L., Cummings, B. M., et al. (2025), BMJ Open / PMC. Cross-sectional protocol. A short, readable survey protocol on student sleep across six medical schools. Study how it names validated tools (Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale), lists predictors, and plans a regression analysis. A good model for masters students planning a questionnaire study.
Effects of Internet Cognitive Behavioral Therapy for Insomnia and Internet Sleep Hygiene Education on Sleep Quality and Executive Function Among Medical Students in Malaysia: Protocol for a Randomized Controlled Trial — Mariappan, V., Mukhtar, F. (2024), JMIR Research Protocols / PMC. RCT protocol. A two-author trial protocol, close in scale to a PhD project. Shows how to state hypotheses for an intervention, describe randomisation and comparison groups, and define primary and secondary outcomes.
'Mindfulness Living with Insomnia': an mHealth intervention for individuals with insomnia in China: a study protocol of a randomised controlled trial — Pan, C., Tie, B., Yuwen, W., et al. (2022), BMJ Open / PMC. RCT protocol. A full randomised trial protocol for an app-based intervention. Useful for the methods section: eligibility criteria, sample size calculation, outcome measures at each time point, and the ethics and dissemination statement.
Rationale, Design, and Baseline Characteristics of Participants in the Health@NUS mHealth Augmented Cohort Study Examining Student-to-Work Life Transition: Protocol for a Prospective Cohort Study — Chua, X. H., Edney, S. M., Müller, A. M., et al. (2024), JMIR Research Protocols / PMC. Cohort protocol. A prospective cohort protocol following university students with apps and wearables. A strong example of the rationale section and of how to describe repeated data collection over time, the same design as the annotated example above.
Using digital health tools for the Remote Assessment of Treatment Prognosis in Depression (RAPID): a study protocol for a feasibility study — de Angel, V., Lewis, S., Munir, S., et al. (2022), BMJ Open / PMC. Feasibility protocol. A feasibility study protocol, a common format for a first PhD study or pilot project. Shows how to set feasibility objectives (recruitment, retention, data completeness) instead of effect-size hypotheses.

Common Research Proposal Mistakes

Supervisors and admission panels see the same problems again and again. Check your draft against this list:

Topic too broad. "The effect of social media on students" is not a study. "Night-time phone use and sleep duration in first-year nursing students in Kerala" is.
No clear gap. If you cannot finish the sentence "Previous studies have not…", the reader will not see why your study is needed.
Literature review as a list. Summarising one paper per paragraph is the most common weakness. Group studies by theme and compare them.
Methods too vague. "Data will be collected and analysed" tells the reader nothing. Name the design, sample size, tools and statistical test.
Objectives and methods do not match. Every objective needs a matching data source and analysis.
Unrealistic timeline. Ethics approval alone can take 1–3 months. Plan for it.
Ignoring the guidelines. Going over the word limit or using different headings can lead to rejection before anyone reads your idea.
Wrong tense. Use future tense for what you will do.
Weak or old references. Include recent peer-reviewed studies, not mostly websites or textbooks.
Copying a sample proposal. Use examples for structure only. Copied text will be caught by plagiarism checks.

Weak vs strong research proposal
Feature	Weak proposal	Strong proposal
Topic	Broad and general	Narrow: one population, one outcome
Literature review	One paper per paragraph	Grouped by theme, ends with a clear gap
Research question	Several vague questions	One main question, 2–4 objectives
Methods	"Data will be analysed"	Design, sample size, tools, named tests
Timeline	Missing or unrealistic	Month-by-month, ethics included
References	Few, old, mixed styles	15–40 recent sources, one style

How to Find Literature for Your Research Proposal

The literature review is where most proposals succeed or fail, and it depends on finding the right papers. Here is a simple, free workflow using Ocean of Papers, which searches 250M+ papers across OpenAlex, PubMed, arXiv, bioRxiv, medRxiv and Europe PMC.

Search your topic. Type a short phrase such as sleep exam performance students into Ocean of Papers. Turn on the PDF filter to see papers with free, legal open-access PDFs (from Unpaywall, PubMed Central, arXiv, bioRxiv and medRxiv). Sort by most cited to find the key studies.
Build a citation map from your best paper. Open a strong result and build a citation map. Switch between Prior works (the papers it builds on) and Derivative works (later papers that cite it) to find the foundations and the newest studies. Click any link to see why two papers are connected. Read more in our citation network guide.
Save to a project and use Discover. Save the papers you need to a library project (free account). Discover then suggests papers your project is missing, with reasons such as "cited by 3 of your papers", so you can spot important studies you have not read yet.
Export your references. Export to BibTeX, RIS or CSV for Zotero or Mendeley, or copy single citations in APA, MLA, Chicago, Harvard or Vancouver.

The free plan includes unlimited search, PDFs and exports, plus 5 new citation maps per month.

For a full method to turn those papers into a structured review, see how to write a literature review. If you already have a DOI, see how to download a research paper by DOI.

Frequently Asked Questions

What are the 7 parts of a research proposal?

The 7 common parts of a research proposal are: (1) title, (2) introduction or background, (3) literature review, (4) research questions, aims or hypotheses, (5) methodology, (6) timeline and budget, and (7) references. Many proposals also add an abstract and a section on expected results and significance.

How long is a research proposal?

It depends on the level. Undergraduate proposals are often 500–1,500 words, masters proposals 1,000–2,500 words, and PhD research proposals 1,500–3,500 words. Grant proposals can be much longer. Always follow the word limit your university or funder gives.

What is a research proposal example for students?

A good research proposal example for students is a short, focused plan on a simple question, like the annotated sleep and exam performance example on this page. It shows each part (title, background, literature gap, question, methods, timeline, references) with a note explaining why it works. For real examples, the published study protocols above are free to download as PDFs.

Is a research proposal the same as a research paper?

No. A research proposal describes a study you plan to do, in the future tense, and has no results. A research paper reports a finished study, in the past tense, with results and discussion. The proposal's background and methods often become the introduction and methods of the final paper. See our research paper examples to compare.

Where can I find a research proposal example PDF?

Published study protocols are the best free research proposal example PDFs because they are real, peer-reviewed plans. Journals such as BMJ Open and JMIR Research Protocols publish them open access, and many are in PubMed Central. Search "study protocol" plus your topic on Ocean of Papers with the PDF filter on.

How do I write a research proposal for a PhD?

A research proposal for a PhD should show an original question, a clear gap in the literature, a feasible method over about three years, and why you are the right person to do it. Read your target supervisor's recent papers, link your idea to their work, and follow the department's word limit and headings.

How is a masters research proposal different?

A research proposal for masters study is shorter, usually covers one study that can be finished in a few months, and does not need to be as original as a PhD proposal. Feasibility, a clear question and a sound method matter most.

Can I use a research proposal template?

Yes. A research proposal template helps you get the structure right, and the one on this page can be copied and filled in. Use templates and examples for structure only, and write all content in your own words.

Next Steps

Start with a narrow question, read the key studies, and use the template above to draft each section. Compare your methods section with one of the published protocols that matches your design.
