How places are given
A standardised score of 121 or more qualifies a child for all 13 schools. Places then go by each school's oversubscription criteria, usually including distance or catchment. Children who score below 121 can be considered through a selection review.
How to register and apply
Register through The Buckinghamshire Grammar Schools in the summer term of Year 5 (children at Buckinghamshire state primary schools are usually registered unless parents opt out). Name the schools on your secondary application by 31 October.
Admissions rules change each year. Check the school’s current admissions policy — area details last checked October 2026.
