The Treehouse School
With just 12 pupils on roll, The Treehouse School in Cholsey, Oxfordshire is among the smallest independent schools a family could consider. A setting this size makes for an unusually intimate environment, where every child is known individually and teaching can be closely tailored. This co-educational, non-denominational day school is inspected by the ISI, the body that oversees independent schools. It will appeal most to families seeking a highly personal alternative to larger mainstream options.
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.

Teaching & academics
The school is inspected by the Independent Schools Inspectorate. With so few pupils, staff are well placed to adapt to the pace and needs of each child rather than teaching to a large group.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A tiny independent in rural Oxfordshire, The Treehouse School offers the kind of close attention that only a roll of around a dozen pupils can provide.
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.
