AGS vs Aylesbury High
How the two compare on Ofsted, GCSE results, places and entrance test — and specialist 11+ tuition for both.
Aylesbury Grammar School and Aylesbury High School are both selected through the The Buckinghamshire Grammar Schools. In 2024/25, AGS recorded a GCSE Attainment 8 of 74.5 (95.2% grade 5+ in English and maths), against Aylesbury High's 74.3 (98.9%). AGS admits about 186 pupils to Year 7 each year and Aylesbury High about 186. AGS's latest Ofsted outcome is Outstanding (2022); Aylesbury High's is Outstanding (2023).
The two Aylesbury grammars — Aylesbury Grammar (boys) and Aylesbury High (girls) — sit on the same Bucks test and share a sibling cross-priority, so Aylesbury families often look at both.

AGS or Aylesbury High: how to choose
Because both schools select through the Bucks Secondary Transfer Test (TBGS), your child sits one test that counts for both — so you do not have to choose before the 11+. The decision comes later, when you list preferences. Weigh three things: which school your child is realistically in catchment for (each ranks qualified applicants differently — see each school's allocation rules), the results and ethos that suit your child, and the practicalities of the daily journey.
On the hard numbers, the two are closely matched: AGS posted a GCSE Attainment 8 of 74.5 and Aylesbury High 74.3 in 2024/25. AGS edges it on that measure, but the gap is small and both sit far above the national average. For most families the deciding factor is access — the score needed in practice and the catchment rules — rather than a fraction of an Attainment 8 point.
