How do you get into Dr Challoner's Grammar?
Dr Challoner's Grammar School is a boys’ grammar school in Amersham, Buckinghamshire, for ages 11–18. Competition for places is strong: only 180 children are admitted to Year 7 each year, selected through the The Buckinghamshire Grammar Schools.

Think Smart Academy has been preparing children for the 11+ for over a decade. Our High Wycombe centre prepares Dr Challoner’s Grammar applicants for the Bucks Secondary Transfer Test. We teach Maths, English, Verbal Reasoning and Non-Verbal Reasoning in separate sessions rather than rushed combined lessons, and track progress with termly mock exams and parent reports. Classes are capped at eight students, and every child starts with a free diagnostic assessment so we can see where they need the most work.

Sources
School data on this page is taken from authoritative sources, last verified 22 May 2026: Ofsted (latest inspection report); the Department for Education’s Compare school and college performance service (GCSE 2024/25); and the school’s own admissions arrangements. A-level figures are the school’s published 2025 results (see the A-level section above for the exact source). Progress 8 is not shown because the DfE cannot calculate it for 2024/25 (no Key Stage 2 baseline after Covid-19). † Most recent inspection was ungraded, so Ofsted issued no new overall grade (overall grades were dropped for state schools in September 2024). The grade shown is from the previous graded inspection, with its year.
