Heartwood House
School summary
Heartwood House is one of the smaller independent options in Harrow, with around 60 pupils across the 11 to 16 age range and a single, focused secondary phase that ends at GCSE. Its compact size means a close-knit community where pupils are unlikely to be lost in the crowd. The school is non-denominational and co-educational, led by Mrs Cathy Haysom. Families considering it should note that, while the Independent Schools Inspectorate judged the quality of education and personal development as sound, the school did not meet the regulatory compliance standards at its inspection.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A small, intimate independent in Harrow that suits families wanting individual attention through to GCSE, though the unmet compliance finding is worth discussing directly with the school.
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.
