School summary
Few state schools post results as commanding as those at The Tiffin Girls' School, a superselective grammar in Kingston upon Thames.

With around 1,256 girls on roll against a capacity of 1,001, the school operates well above its nominal size, placing it firmly in the large band. Around 40 per cent of pupils speak English as an additional language, reflecting a broad and ambitious intake.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A school for academically driven girls who relish a demanding two-stage entrance test and an Outstanding environment to match.
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.
