Extenuating circumstances and mitigation: how they actually affect your marks

By Riley Jordan · Last updated 16 August 2026 · Foundations

Illness, bereavement, a family emergency, a mental health crisis — most students face something disruptive at some point in a degree. UK universities have a formal process for this, usually called extenuating circumstances (also “mitigating circumstances” or “special circumstances” depending on the institution). It is worth understanding what it actually does, because the common assumption — that it bumps up a mark — is usually wrong.

What it is for

Extenuating circumstances processes exist to make sure a mark reflects your ability, not a temporary crisis you were experiencing during an assessment. The regulations exist so this is handled consistently and fairly, rather than case-by-case at a marker’s discretion.

What it usually does not do

A common misconception is that approved circumstances directly raise a mark. In most UK institutions, they do not. Markers grade the work in front of them on its academic merit; extenuating circumstances panels are a separate process that does not typically re-mark or inflate a script.

What it usually can do

Instead, an approved claim more commonly leads to one of a small set of remedies, decided by your institution’s regulations rather than the marker:

  • An extension to a coursework deadline, agreed in advance or shortly after the circumstances arose.
  • A deferral — sitting the assessment at a later date as a first attempt, rather than as a resit, so it does not carry the mark cap that a genuine resit might.
  • Discounting the assessment from your average entirely, if your remaining results are sufficient to demonstrate your ability.
  • Being allowed to proceed to the next year or graduation despite a technical shortfall, at the panel’s discretion within the regulations.

Which of these applies depends entirely on your institution’s own extenuating circumstances policy — this varies more than almost anything else covered in these guides, so treat the list above as the shape of what is possible, not a guarantee of any one outcome.

Evidence and timing

Claims are almost always evidence-based: a doctor’s note, a counsellor’s letter, a death certificate, or similar. Universities generally will not investigate the content of the evidence in detail, but they do check it exists and covers the relevant dates. Timing matters too — most institutions have a submission window (often a matter of days to a few weeks after the affected assessment), and late claims are frequently rejected on procedural grounds alone, regardless of how genuine the circumstances were. If something is affecting you, the single most useful thing you can do is tell your department as early as possible, even before you have formal evidence in hand.

Ongoing or long-term circumstances

For circumstances that are not a one-off event — a chronic illness, a disability, an ongoing caring responsibility — the right route is usually not a one-time extenuating circumstances claim but a reasonable adjustments or learning support plan through your disability or wellbeing service, agreed at the start of the year rather than after each individual assessment.

The practical takeaway

Extenuating circumstances processes are there to protect you from a bad snapshot, not to change what a mark means. If you are dealing with something disruptive, contact your department’s student support or registry team as early as you can — the process only works if it knows about your situation before, not after, it is too late to help.
