Dr Challoner's Grammar or RGS High Wycombe: how to choose
Because both schools select through the Bucks Secondary Transfer Test (TBGS), your child sits one test that counts for both — so you do not have to choose before the 11+. The decision comes later, when you list preferences. Weigh three things: which school your child is realistically in catchment for (each ranks qualified applicants differently — see each school's allocation rules), the results and ethos that suit your child, and the practicalities of the daily journey.
On the hard numbers, the two are closely matched: Dr Challoner's Grammar posted a GCSE Attainment 8 of 73.9 and RGS High Wycombe 73.9 in 2024/25. They are effectively level on that measure, and both sit far above the national average. For most families the deciding factor is access — the score needed in practice and the catchment rules — rather than a fraction of an Attainment 8 point.

Sources
School data is taken from authoritative sources, last verified 26 May 2026: Ofsted (Dr Challoner's Grammar, RGS High Wycombe); the Department for Education’s Compare school and college performance service (GCSE 2024/25); and each school’s own admissions arrangements. A-level figures are each school’s published 2025 results where available. 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.
