Teaching & academics
The ISI's "excellent" judgement reflects a school where teaching and outcomes are clearly strong, and the matching rating for personal development points to attention to the whole child rather than results alone. Around 8 per cent of pupils receive SEN support, indicating the staff are used to accommodating a range of learning needs. Academic scholarships are available to current pupils, alongside awards in music and sport.

Beyond the classroom
Sport features prominently, with cricket and swimming among the mainstays and road tennis offering something less commonly found. Music and sport scholarships signal that talent in these areas is recognised and nurtured.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A small, single-sex prep with an "excellent" ISI record and a clear focus on developing boys as individuals. Fees run from £17,313 to £21,195 a year, with bursaries of up to 40 per cent available to existing pupils whose circumstances change.
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.
