Sutton Grammar School
School summary
Among the country's superselective boys' grammar schools, Sutton Grammar combines fierce academic competition for places with notably calm conduct, earning an Outstanding rating from Ofsted for pupil behaviour at its 2022 inspection. Now home to around 1,043 boys against a stated capacity of 840, the school is running well over its intended size, reflecting steady demand. Entry at 11 is restricted to just 150 places, assessed in English and Maths through a bespoke test as part of the Sutton Selective Eligibility Test consortium. Just over a third of pupils speak English as an additional language, and very few are eligible for free school meals.
How hard is it to get in?
Exceptionally competitive · 5 of 5 on the Passmate scale. Demand here is among the very highest of any selective school in England - a strong exam performance matters more than at almost any other school.

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.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
A high-achieving boys' grammar where exceptional results meet Outstanding behaviour, but families should weigh the tightly contested 150 places and a roll that comfortably exceeds the school's stated capacity.
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.
