How far offers reached
Each bar shows how far from Sir Joseph Williamson's Mathematical School the last child offered a place lived, under the last admission rule the offers reached. Up to five years, on one scale.
Qualifying is not the same as being offered a place.
A score of 478 or more in the Medway Test (GL Assessment, written for Medway Council) means your child can be considered. If more children qualify than there are places, the school gives places using its admission rules, in order. The figures below show how far those rules reached in past years. They are history, not a prediction: they change every year with who applies.

Source: Medway Council, checkedWhat the words mean
- National Offer Day:
- the first offers, made on 1 March (or the next working day).
- Final:
- how far offers had reached later, after places were offered from the waiting list.
- Admission rule:
- schools give places rule by rule, in order. The distance is only how far the last rule reached.
- N/A or “All offered”:
- no distance was needed to decide places under that rule, for example because everyone who applied under it got a place.
- No figure published:
- nobody published a figure for that year, or we have not checked one yet. We never fill a gap with a guess.

Applications and offers, September 2026 entry (Department for Education)
How many families applied to Sir Joseph Williamson's Mathematical School and how many places it offered. Applicants per place is all applications divided by offers. Families apply to several schools and not every applicant qualifies, so it is not the chance of a place.
