Ewell Castle School
School summary
Set on a site dating back to its founding in 1926, Ewell Castle is a mixed independent school in Epsom taking pupils from age two through to eighteen. With around 640 on roll and a notably low pupil-to-teacher ratio of roughly six to one, classes are small and contact with staff is close. The Independent Schools Inspectorate rated the school good overall and, tellingly, excellent for personal development, with all compliance standards met. A firm line on mobile phones - Yondr pouches for Years 7 to 11 and a school-day ban introduced in 2024 - signals a focus on attention and presence under Principal Mr Silas Edmonds.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A small, attentive independent where strong GCSE outcomes meet an excellent record on personal development. Best suited to families who value close support and a screen-free school day.
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.
