Appeal Deadlines and Late Evidence
Deadlines in the appeals process aren't just administrative - missing one can mean your evidence is excluded, or your hearing delayed into a less favourable timetable.

The 20-school-day minimum
For normal admissions rounds, the School Admissions Appeals Code requires appeal timetables that normally give parents at least 20 school days from the date of refusal to lodge an appeal. Some admission authorities allow longer, and the exact deadline - a specific date, not just “20 school days” - should be stated clearly in your refusal letter. Always work from that stated date rather than calculating it yourself, since school-day calendars vary by area and by year, and the precise legal position is set out by the admission authority itself.
Why the deadline matters beyond the obvious
Missing the deadline doesn’t automatically end your case - late appeals are usually still considered, particularly with a good reason, but they may be heard later than appeals lodged on time and are subject to the admission authority’s own arrangements, so there’s no guarantee of the same outcome as an on-time appeal. If you think you’re going to miss the deadline, contact the admission authority before it passes, not after - explaining the reason in advance is far stronger than explaining it retrospectively.
Late evidence is a separate issue
Even once your appeal is lodged on time, admission authorities and panels usually set a further deadline for submitting supporting evidence ahead of the hearing - check your appeal confirmation or panel correspondence for this date specifically, as it’s often different from the appeal deadline itself. The panel may not be able to consider new information or evidence at all if you haven’t already submitted it in writing, so a piece of evidence mentioned for the first time at the hearing itself is a real risk, not a formality.
The hearing notice period is a separate deadline again
Once your appeal is accepted, you should normally get at least 10 school days’ notice of the actual hearing date - a third, distinct timeline from both the original appeal deadline and the evidence deadline. Keep track of all three separately rather than assuming one date covers everything.
How to avoid evidence problems
- Start gathering evidence (medical letters, professional references, documentation) as soon as you decide to appeal - some evidence, like a specialist’s letter, can take weeks to obtain
- Submit a complete case by the evidence deadline rather than holding back items you’re still waiting on, where possible
- If a specific piece of evidence genuinely can’t arrive in time, tell the admission authority in advance and explain why, rather than submitting it unannounced at the hearing
Common mistakes parents make with deadlines
- Calculating the deadline yourself from ‘20 school days’ instead of using the specific date stated in the refusal letter
- Waiting until the deadline is close before starting to gather evidence that can take weeks to obtain, such as a specialist’s letter
- Submitting evidence at the hearing itself, unannounced, rather than by the stated evidence deadline
- Assuming a missed deadline ends the case entirely, rather than contacting the admission authority as soon as possible
Quick FAQ
What counts as a school day for this deadline?
It follows the specific school-day calendar for the relevant local authority or academy trust, which varies by area and year - this is exactly why you should work from the specific date stated in your refusal letter, not calculate it yourself.
Will a late appeal definitely be heard?
Not guaranteed, but late appeals are usually still considered, particularly with a good reason. Contacting the admission authority before the deadline passes, rather than after, gives you the strongest chance.
