Teaching & academics
The curriculum is built around the IB, a globally recognised qualification that rewards breadth and independent thinking rather than narrow specialisation. The ISI's "excellent" rating for education indicates strong teaching and outcomes across the school. Families considering the school should be comfortable with the IB route, which differs from the more common A-level pathway.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
An internationally minded day school offering the IB from the early years to sixth form, with bursaries of between 10 and 100 per cent widening access. It will suit families drawn to a global curriculum and an inclusive, well-supported environment.
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.
