About the GL Assessment 11+ Test for Aylesbury Grammar School (AGS)
Aylesbury Grammar School (AGS) is a boys state grammar school in England that uses the GL Assessment 11+ entrance test to select pupils for Year 7 admission. The school admits approximately 186 Year 7 pupils each September, and applications must be made through your home Local Authority via the Common Application Form (CAF) — never directly to the school.
The GL Assessment 11+ is one of two main 11+ test providers in England (the other being CEM, now retired in many regions). The Bucks test typically consists of multiple papers covering English, Mathematics, Verbal Reasoning, and Non-Verbal Reasoning. Scores are standardised against the cohort age distribution, so younger pupils are not disadvantaged. Each school sets its own qualifying mark (pass mark).
For 2027 entry, the GL Assessment test is sat in mid-September 2026 and results are released to parents on mid-October 2026 — crucially, before the Common Application Form deadline of Friday 31 October 2026, giving parents time to consider results before listing school preferences. National Offers Day is Monday 1 March 2027, when Local Authorities issue Year 7 secondary school offers.
Aylesbury Grammar School (AGS) is academically selective — pupils must achieve the qualifying mark in the 11+ test to be eligible for a place. If applications exceed the published admission number (186 places), the school applies its oversubscription criteria (looked-after children, FSME, siblings, distance) to allocate places. This page is updated each year with the latest verified admissions criteria, key dates and oversubscription rules.

Catchment Area for Aylesbury Grammar School
Admission to Year 7 is through the Buckinghamshire Secondary Transfer Test (the 11+), produced by GL Assessment and shared across the 13 schools of The Buckinghamshire Grammar Schools (TBGS) — so a child sits it once. It is two multiple-choice papers of around 45 minutes each: one covering comprehension, technical English and verbal reasoning, the other non-verbal reasoning, spatial reasoning and mathematics. Scores are age-standardised and a child needs a qualifying standardised score of 121. Children at Buckinghamshire state primaries are entered automatically; families elsewhere register through Buckinghamshire Council.
Aylesbury Grammar School operates a designated catchment area around Aylesbury; you can check whether an address falls inside it using Buckinghamshire Council's catchment checker. After qualified looked-after children, places go first to catchment boys eligible for free school meals (with up to six places for those scoring 115–120), then siblings of boys at the school — and of girls at Aylesbury High School — then boys with an exceptional medical or social need, and finally other qualifying catchment boys ranked by straight-line distance from the school. Always confirm the current catchment map and criteria in the school's admissions booklet.
