Colchester Royal Grammar School
School summary
A selective boys' grammar in Colchester with a Christian character, Colchester Royal Grammar combines day and boarding places and entry at age 11. The school is notably oversubscribed: around 1,059 pupils are on a roll built for 777, making it considerably larger than its stated capacity. Entry is competitive, with 128 places allocated through the CSSE consortium each year. A 2021 Ofsted inspection presents a mixed picture, however: while the quality of education and sixth form were judged Good, behaviour, personal development, leadership and the overall rating were all found to be Inadequate.

Watch Passmate decide how to teach.
Answer as a child would. Left: what they see. Right: what it learns about them.
An academically outstanding boys' grammar whose results are among the strongest you will find, set against an Ofsted report that flags real concerns beyond the classroom. Families drawn by the results should read the full inspection findings carefully.
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.
