Dr Challoner's Grammar School
Amersham, HP6 5HA · Buckinghamshire · Grammar school
1st of 36 secondary schools in Buckinghamshire we can score, 37 in total — the rest without enough published data. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to the 135 schools whose pupils have similar backgrounds — a tougher field — and it places 8.2/10 among them, against 9.8/10 nationally. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.
How this is worked out
| Measure | Percentile | Weight | Adds |
|---|---|---|---|
| Ofsted | 94 | 35% | 3.28 |
| Grade 5+ English & maths 2024/25 | 96.2 · 98 | 30% | 2.93 |
| Progress 8 2023/24 | 1.18 · 99 | 25% | 2.48 |
| Attainment 8 2024/25 | 73.9 · 98 | 10% | 0.98 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
Get to know the school
How it's doing. In 2024/25, 96.2% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 73.9, compared to the national median of 44.6. Progress 8 was +1.18 in 2023/24, indicating better progress than pupils nationally who started from the same place. Narrow the comparison to the schools whose pupils have similar backgrounds — a tougher field — and it places 8.2 out of 10 among them, against 9.8 out of 10 nationally. Ofsted rated the school Outstanding in December 2024.
Beyond the classroom. Pupils join Drama Clubs, Senior and Junior Musicals, and Summer Plays, supported by a Student Theatre Technicians Team. Sports include Fencing, Climbing, Boxing, Gym, Yoga, Badminton, Table tennis, and Softball. Trips cover trekking in Morocco, canoeing in France, and watersports at Calshot.
Getting in. There are 1368 pupils in a school with 1356 places, meaning it is over capacity by 12. The school is over its stated capacity, so places are competitive.
Worth asking on a visit. How does the school manage the 12-pupil overage in daily operations? What support is available for pupils aiming to improve their Progress 8 scores? How are the theatre and sports facilities scheduled to avoid conflicts?
