Mitigating circumstances at a UK university: extensions, deferrals and evidence

Choose an extension or deferral, explain assessment impact and prepare evidence.

Key takeaways

• An extension gives you extra submission time; a deferral moves an assessment to a later occasion. Your university decides which request and outcome fit.
• Explain how the circumstances affected preparation, attendance or submission, and when; describing the event alone is only part of the account.
• Evidence requirements depend on the route: Manchester’s eligible coursework extension requests require no supporting evidence, but still need an explanation of impact.
• Find your university’s application cut-off now, even if you are still gathering evidence. At UCL, an application alone does not tell you to miss an assessment.
• Read the actual outcome before changing your calendar, and confirm anything unclear about attempt status, progression or completion.

If illness, bereavement or another serious disruption affects an assessment, start with what you need: more time to submit coursework, or an opportunity to take an assessment later. Your university decides which request and outcome fit. Find its application cut-off now, even if you are still gathering evidence.

Universities use names such as mitigating circumstances and extenuating circumstances. Their deadlines, evidence requirements and assessment rules differ. The UCL and University of Manchester examples below show why copying a friend's procedure can send you down the wrong route. These examples concern taught assessments; research-degree thesis procedures can be different.^[2][3][4]

Choose the request for the affected assessment

An extension gives you extra submission time. A deferral moves an assessment to a later occasion. At UCL, both can be outcomes of an extenuating circumstances claim; the university chooses the mitigation.^[2]

Manchester has a separate extension form for eligible coursework, projects and dissertations. Its extension procedure excludes assessments such as group work, presentations and timed examinations. For an exam, use the mitigating circumstances route rather than treating it as coursework with a movable deadline.^[3]

Think through the practical difference before requesting an outcome. If a few extra days would let you finish the assignment, explain that. If you cannot take an assessment at the scheduled time, explain the period affected and ask about the later-assessment option. Do not select an extension merely because it sounds less disruptive.

Explain what the circumstances stopped you doing

A circumstance and its academic impact are two different parts of the account. “My father was seriously ill” describes an event. The application also needs to explain how it affected preparation, attendance or submission, and when.

Manchester's policy lists illness or injury, worsening physical or mental health conditions, a close family member's death or critical illness, and significant personal crises among possible grounds. It normally excludes holidays, poor time management and misreading an assessment timetable. Examination stress without a diagnosis of illness or supporting medical evidence is also normally excluded.^[4]

For your own account, answer a concrete question: what assessment work became difficult or impossible during the affected dates? That might be concentrating on a reading task, attending a practical assessment or completing the final analysis. Describe what actually happened; avoid guessing at a diagnosis or adding stronger language to make the account sound persuasive.

Build a dated account, then match the evidence

Draft the account before uploading documents so you can see what each document needs to establish:

• Identify the module, assessment and original deadline or exam date.
• Give the disruption's start date and end date, or say it is ongoing.
• Explain the effect on the particular work or assessment.
• State the outcome you are requesting and why it would address that effect.
• Identify the evidence supplied and anything still outstanding.

Hypothetical example: “My Research Methods report is due on 18 November. From 11 to 15 November, an unexpected family emergency required me to provide care, and I could not complete the planned analysis during those days. The introduction and methods are drafted. I am requesting extra submission time to complete the analysis and discussion. I have attached the supporting correspondence available to me.”

This illustrates the structure of an account, not a successful application. Replace every detail with your own. If the effect continued after the event, explain that period too; do not assume a document about one date explains the whole request.

For a UCL claim, medical evidence should:

• Be on headed paper or carry an official stamp or seal; electronic scans are accepted.
• Normally have been produced within the last three months.
• Identify you by full name and give the date, plus the provider's full name, role, organisation and signature.
• Explain the condition, relevant dates and assessment impact, allowing for details that do not apply to your circumstances.

It must cover the full claimed period. A retrospective note based only on your later report of illness is likely to be rejected. For long-term reasonable adjustments, UCL may accept evidence produced within 12 months; that is a separate support route. Non-medical evidence can include a crime report or court document.

Evidence requirements also depend on the route. Manchester's eligible coursework extension requests require no supporting evidence, but still need an explanation of impact. Its mitigation procedure allows flexibility in evidence, including particular protections against repeatedly requesting disability evidence. If documentation is difficult to obtain, its Student Support and Wellbeing team can help identify suitable evidence.^[3][5]

Submit through the university's route before its cut-off

At UCL, submit through Portico's MyStudies extenuating circumstances area as soon as possible. The 2026–27 regulations say no more than one week (five working days) after the first affected assessment. They exclude weekends, UK bank holidays and UCL closure days when counting working days. The student FAQ shortens this to one week; use the regulation's working-day definition and ask your department to confirm a cut-off affected by closures. Its departmental panel considers the claim, with escalation where needed.^[2][6]

At Manchester, use the extension form on or before the eligible coursework deadline. Once that deadline has passed, use the mitigating circumstances form. The mitigation deadline for coursework is seven calendar days after submission was due; for exams, use the School's published end-of-semester deadline. Its programme handbook or equivalent documentation provides the online mitigation form.^[3][5]

Keep a copy of what you submitted and the submission confirmation. At UCL, an email confirms successful submission; a draft saved under “claims not submitted” has not reached the panel. The decision is available in Portico after an email notification.^[6]

If evidence or a decision is still pending

UCL tells students awaiting evidence to submit the claim on time, flag that evidence will follow and supply it within four weeks of the application. While a decision is pending, its guidance says to attend or submit the assessment if you can. An application alone does not tell you to miss it.^[6]

If you have missed Manchester's mitigation cut-off, explain why you could not notify the School earlier. A late application needs a strong, acceptable reason; the 2026 procedure gives evidenced hospitalisation or incapacity as examples. Contact your School promptly rather than waiting for results.^[5]

Turn the decision into a workable assessment plan

Read the actual outcome before changing your calendar. Record the new deadline or assessment period, the submission method and any further instructions. Ask the department to confirm anything unclear about attempt status, progression or completion.

For example, UCL warns that deferral to its Late Summer Assessment period delays a finalist's award and graduation, and that deferred in-person assessments require attendance on campus.^[6] A later assessment therefore needs planning beyond the assessment itself.

If a request is refused, read the reason and identify the available review route immediately. UCL allows a review for significant procedural error within two weeks of the mitigation decision; disagreement with academic judgement is not a review ground.^[2]

If completion dates change, speak first to your university's academic and international student advisers about your study arrangements. Then revisit any career plans built around the old dates. Through our Post Study Career Support^[1], we review your current situation and goals, plan relevant career experience and provide guided support. You can speak to a career advisor through the page's phone, email or query form once you know the revised academic timetable.

FAQs

Can I use medical evidence from India for a mitigating circumstances claim?

UCL says it may consider evidence from a practitioner outside the UK if they are registered with an equivalent overseas professional medical body. Evidence in another language must have a certified translation. It also requires independence, so a medically qualified close relative cannot provide it. This is UCL's policy; confirm your own institution's requirements before arranging a translation.

Can I request mitigation if I have already sat the exam?

Submitting an attempt does not always close the route. UCL's FAQ describes applying approved mitigation retrospectively when a student takes an assessment while a claim is pending. Manchester's exam mitigation deadline follows its assessment period. Apply promptly under your university's rules rather than waiting to see whether the mark is disappointing.^[5][6]

What if the same condition affects several deadlines?

Ask about ongoing support alongside the immediate assessment request. Manchester directs students with foreseeable effects from chronic conditions to its Disability Advisory and Support Service and advises updating the support plan if circumstances change. A sudden worsening can still be a ground for mitigation.^[4]
