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

Under the School Admissions Appeals Code, you must be given at least 20 school days from the date of refusal to lodge your 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.

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. Evidence submitted late can be excluded from consideration entirely, or accepted only at the panel’s discretion, which is a risk not worth taking if it can be avoided.

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
