Aylesbury, Buckinghamshire · Buckinghamshire
Aylesbury Grammar School
Was literally the same co-educational school as Aylesbury High until they split by gender in 1959 — the two still give each other's siblings admissions priority today.
Aylesbury Grammar sets no score requirement above Buckinghamshire's flat county-wide threshold, and its own admissions policy confirms oversubscription is resolved by catchment and distance, never by ranking test scores. One piece of local history worth knowing: AGS and Aylesbury High School were originally one co-educational school before splitting by gender in 1959, and each school's own admissions policy still gives priority to the other's siblings today — a cross-reference that would otherwise look like a strange anomaly.

Admissions
- Admissions authority
- The school sets its own test and criteria
- Entrance test board
- The Buckinghamshire Secondary Transfer Test (STT), administered county-wide by Buckinghamshire Council on behalf of the county's 13 grammar schools (collectively 'The Buckinghamshire Grammar Schools'). GL Assessment is named by tutoring sites as the setter, though not confirmed on any council or school primary page.partly verified
GL Assessment is named only by tutoring sites, not by the school or Buckinghamshire Council directly.
- Test format
- Two age-standardised multiple-choice papers sat on the same day in autumn of Year 6: Paper 1 covers verbal/English skills; Paper 2 covers maths and non-verbal/spatial reasoning. The three component scores are combined into a single Secondary Transfer Test Score (STTS) — the school's own policy states they are 'added together' without specifying exact weights, though secondary sources describe a 50% verbal / 25% maths / 25% non-verbal split.
- Qualifying / pass mark
- An STTS of 121 for September 2027 entry — the same flat, county-wide threshold used identically by every Buckinghamshire grammar school. A special quota of up to 6 places allows catchment-resident, Pupil-Premium-eligible boys scoring 115-120 to qualify under a lowered bar.
- Superselective?
- No
Confirmed directly from the school's own admissions policy: a single flat qualifying threshold with no higher or banded requirement for general entry. Oversubscription among qualified boys is resolved by priority category (care status, catchment-and-Pupil-Premium, siblings, staff children, medical need, catchment, then all other qualified boys) and then straight-line distance — never by rank-ordering test scores. This is a catchment-and-distance model, the same structure confirmed at other Buckinghamshire grammar schools researched.
Catchment & priority criteria
A defined catchment area exists and materially affects priority, covering Aylesbury and surrounding towns and villages including Princes Risborough, Long Crendon, Ludgershall, Stewkley and Edlesborough (per secondary directory sources) — published only as an interactive map on the school's and council's sites, not as a written boundary.
