Sir Henry Floyd Grammar School
School summary
An Ofsted rating of Outstanding across every category - quality of education, behaviour, personal development, leadership and sixth form - marks Sir Henry Floyd as one of Aylesbury's most strongly performing schools. This is a large, mixed selective grammar in Buckinghamshire, with around 1,348 pupils currently on roll against a stated capacity of 1,305, so it is operating slightly over its formal limit. The mix of pupils reflects its area, with about one in six speaking English as an additional language. Families looking for an academically ambitious state-funded environment with a sixth form will find much to consider here.
How hard is it to get in?
Very competitive · 3 of 5 on the Passmate scale. Demand comfortably exceeds the 180 Year 7 places each year - a clear pass, not a borderline one, is what wins a place.
Where every mark matters.
Places are limited and demand is high, so exam performance is what sets candidates apart. Passmate turns the months ahead into ten focused minutes a day on the exact topics this school tests.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A consistently high-achieving grammar with a clean sweep of Outstanding judgements - but with 180 places and selective entry, competition for a place is real.
That’s where Passmate comes in. Tutoring is the most effective thing in a child’s preparation - a well-tutored child can outperform the vast majority of their peers. Passmate works alongside your tutor, not instead of them: it learns how your child thinks, finds the gaps, and shows the tutor exactly where to spend each session - so the limited time you have lands on what actually decides a place.
Works alongside your child’s tutor - not instead of them.
