Chesham Grammar School
School summary
Chesham Grammar School pairs sustained academic strength with consistently high marks from inspectors across every area of its work. A large mixed grammar in Chesham, Buckinghamshire, it currently teaches around 1,326 pupils against a stated capacity of 1,219, so it is operating comfortably above its intended size. Entry at 11 is selective, with 180 places each year, and a sixth form that Ofsted judged Outstanding. With a low proportion of pupils on free school meals and a sizeable number who speak English as an additional language, it draws an academically focused community.
How hard is it to get in?
Highly competitive · 4 of 5 on the Passmate scale. Applications far outnumber the 180 Year 7 places each September, so exam performance matters more here than at most selective schools.
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 high-performing, oversubscribed grammar where strong results and Outstanding inspection judgements go hand in hand. Families should expect a genuinely competitive 11+ via the Buckinghamshire consortium.
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.
