No UK body publishes a dissertation failure rate. The national datasets measure whole degrees, not individual assessments — the Office for Students sets a minimum completion threshold of 75 per cent for full-time first-degree students, and nothing below that level of granularity is collected. What actually determines your outcome is your own university’s regulations on compensation, reassessment and mark capping, and those regulations differ substantially between institutions.
This page sets out the national picture honestly, then the mechanics from three named UK universities’ published rules, so you can find your own equivalent quickly.
What the national data does and does not contain
The Office for Students publishes sector-level measures of continuation, completion, progression and degree attainment for higher education in England. Under condition B3 it sets published numerical thresholds — minimum expectations for the percentage of students achieving positive outcomes on each indicator.
| Indicator | OfS numerical threshold, full-time first degree |
|---|---|
| Continuation | 80% |
| Completion | 75% |
| Progression | 60% |

Two caveats belong with those figures. The OfS itself states that “performance below a numerical threshold does not mean that a provider is not meeting our minimum expectations”, because context is part of its judgement. And these are thresholds for providers, not probabilities for you: they describe the level below which the regulator starts asking questions of an institution.
More importantly for the question on this page, none of it is about dissertations. Completion measures whether a student finishes a qualification. It does not record which assessment they struggled with, and no UK body collects assessment-level outcomes across institutions. Any figure presented online as “the UK dissertation failure rate” is therefore an invention or a single department’s internal number generalised without warrant. If you need a citable statistic, cite the OfS completion measure for what it is — a degree-level indicator — and say so.
The mechanics: three named universities, three different regimes
What happens after a failing mark is decided entirely by your institution’s assessment regulations. Three published examples show the range.
University of York — compensation first, then one capped reassessment
York’s guide for bachelors undergraduate programmes sets the pass mark at 40 for undergraduate-level modules and offers two routes to the credit if you do not reach it.
Compensation. A mark in the 30–39 band is a “marginal fail/compensated pass” where you are eligible: “if your mark for a module is in the 30-39 range, you may still be able to get the credits for the module if your performance in other modules is good enough to compensate”. The limits are firm — you “cannot have failed more than 40 credits and there can be no ‘outright’ fails (so, no marks below 30)”.
Reassessment. A mark below 30 “cannot be compensated and you will have to be reassessed”, and reassessment is offered “as long as the number of failed credits in the Stage does not exceed 80 for Stage 1 or 60 for Stages 2 or 3”. Crucially, “reassessment marks (resit marks) are used for students’ degree classifications, capped at the pass mark for the module”.
The hard stop. “You can only be reassessed in a module once… If you fail a module and its reassessment, you will not be able to progress and will fail the programme.” A lower award may still be available. And two exceptions are worth marking: “though most modules are able to be reassessed, some may not be”, and “in some programmes (for example, where professional requirements have to be met) compensation and reassessment may not be an option”.
Oxford Brookes University — one resit, then one retake
Brookes gives one resit opportunity per failed assessment, and states the cap plainly: “the mark that you achieve for a resit will be capped at the pass mark — this means 40% for modules up to level 6”, with the cap lifted only where exceptional circumstances are approved. Fail the resit and there is “only one opportunity to retake the module” — a retake meaning enrolling in the module again as a new instance, which carries a first attempt and a resit of its own. And a line worth knowing before you ask: “once you pass an assessment, you cannot resit it; and once you pass a module, you cannot retake it.”
UWE Bristol — free resit, expensive retake
UWE distinguishes the two on cost as well as process. A resit is an attempt at the failed assessment tasks only, normally automatic, and “the University does not charge students to take a resit”. A retake “is when you study a whole module for a second time”, with all assessments redone and full tuition fees charged. Its pass marks are 40 per cent at undergraduate level and 50 at postgraduate, and no marks carry over between attempts.
The four things that decide your outcome
Read across those regulations and the same four variables appear, in the same order.
- How far below the pass mark you are. The gap between a marginal fail and an outright fail is a real regulatory boundary, not a matter of degree. At York, 30 is the line: above it compensation may be possible, below it reassessment is compulsory.
- Whether the module can be compensated at all. Many programmes designate the final-year project or dissertation as a module that must be passed in its own right, and professional programmes commonly remove both compensation and reassessment. This is the single most important thing to check, and it is in your programme regulations rather than the general university ones.
- Whether the resit mark is capped. It usually is, at the pass mark, and the capped mark — not your actual resit performance — is what feeds your classification. On a dissertation carrying a large share of final-year credit, that cap has a visible effect on the degree you finish with, which is why the classification algorithm matters as much as the mark.
- How many attempts remain. Typically one reassessment, sometimes followed by one retake at full fees. Nobody gets an indefinite series.
What “failing the programme” actually means
It rarely means leaving with nothing. Where a student fails a module and its reassessment, York’s guidance notes they “may, however, be eligible to receive a lower award” — typically an ordinary degree without honours, or an exit qualification such as a Diploma of Higher Education, depending on the credit already achieved. It is not the outcome anyone wants, and it is a materially different thing from having no qualification at all.
Two other outcomes exist and are worth naming. A dissertation can be failed on academic misconduct grounds rather than on quality, which follows a different procedure entirely and is covered in our guide to legitimate and criminal dissertation help. And a project can be stopped before it produces anything markable — most often because data collection began without approval, which is why ethics approval is a gate rather than a formality.
What to do in the first week after a failing mark
- Find your programme regulations, not the general ones. You are looking for three things: whether the dissertation module can be compensated, whether it can be reassessed, and what the cap is.
- Get the feedback in writing and read it as a specification. A resubmission is marked against the same criteria; the marker has told you which ones you missed.
- Ask about the deadline immediately. Resubmission windows are set by the examination board and are usually measured in weeks or a small number of months, not open-ended.
- Establish whether extenuating circumstances apply. Where they do and are accepted, the cap may be lifted — Brookes removes it where exceptional circumstances are approved. Late claims are much harder to run than timely ones.
- Ask what “resubmission” means in practice for your module. Revising the existing dissertation is a different job from collecting new data, and departments differ on which they will accept.
The failures that are avoidable, and when
Most dissertations that fail on quality rather than conduct do so for reasons that were visible months earlier. A question too broad to answer with the data available. A methodology that describes rather than justifies. A discussion that restates findings instead of interpreting them against the literature — the single most common reason a competent project lands in the third-class band. And a reference list too thin to demonstrate engagement, which is graded as range rather than count, as we set out in our answer to how many references a dissertation should have.
Every one of those is a design problem, and the cheapest place to fix a design problem is the proposal — which is why our guide to writing a dissertation proposal spends most of its length on narrowing the question rather than on formatting the document. The second cheapest place is the first supervision meeting after your first chapter draft.
If the risk you are managing is not the design but the writing — chapters that will not start, a bibliography that never matches the handbook, a deadline arriving faster than the draft — Tesify structures and drafts your dissertation with you, keeps the references formatted as you cite, and checks your drafts before your university does. It is free to start and everything stays 100% written by you.
Frequently asked questions
What is the dissertation failure rate at UK universities?
No UK body publishes one. National datasets measure continuation, completion and progression at qualification level, not outcomes for individual assessments, so any quoted dissertation failure rate is unsourced. The nearest published figure is the OfS completion threshold of 75 per cent for full-time first-degree students, which is about whole degrees.
Can you resit a dissertation?
Usually once, subject to your regulations. York states that “you can only be reassessed in a module once”, and Oxford Brookes gives one resit followed by at most one retake of the module. Some modules and some professional programmes allow neither.
Is a dissertation resit mark capped?
Almost always at the pass mark. Brookes caps a resit “at the pass mark — this means 40% for modules up to level 6”, and York confirms that capped resit marks are the ones used in degree classification. Approved exceptional circumstances can remove the cap.
What is compensation, and can it cover a failed dissertation?
Compensation awards you the credit for a marginally failed module on the strength of your other results — at York, for marks in the 30–39 range, up to 40 credits, with no marks below 30 anywhere. Whether it can cover a dissertation depends on your programme; final-year project modules are frequently designated as ones that must be passed outright.
Do I have to pay to resit my dissertation?
Often not for a resit and usually yes for a retake. UWE Bristol states that it “does not charge students to take a resit”, while a retake means studying the whole module again with full tuition fees. Confirm with your own institution before assuming either.
Will failing my dissertation stop me graduating?
Not necessarily. Passing at reassessment normally secures the credit at a capped mark. Where a module and its reassessment are both failed, York notes students “may… be eligible to receive a lower award”, such as an ordinary degree or an exit qualification, rather than leaving with nothing.
How long do I get to resubmit?
It is set by your examination board and communicated with the result, typically a defined window rather than an open deadline. Ask the moment you receive the outcome, because the window often starts from the board date rather than from when you read the email.
Does a capped resit mark affect my degree classification?
Yes. York is explicit that reassessment marks “are used for students’ degree classifications, capped at the pass mark”, so the capped figure is what enters the calculation. On a heavily weighted final-year project the effect on the overall award mark is real.
Can extenuating circumstances remove the cap?
Where they are accepted, often yes — Brookes lifts the cap for approved exceptional circumstances. The claim has to be made through your institution’s process and is far stronger when submitted at the time rather than after the result.
Is failing a dissertation common?
Nobody can answer that with data, because no one collects it. What is known is that completion at qualification level sits well above the OfS’s 75 per cent threshold across most of the sector, which is a different measure of a different thing — and the honest answer is that your department, not a national statistic, is the only place a real figure could come from.
What if I failed because of academic misconduct rather than quality?
That runs through a separate procedure with different outcomes, which can include a voided submission and penalties beyond the module. It is not a resit question, and the first step is to read your academic integrity regulations and seek advice from your students’ union.
