Check the area around this school
13th 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.
Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds — 9.5/10 against 639 of them, against 9.5/10 nationally. So this is not simply a reflection of who attends. 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 | 52 | 35% | 1.84 |
| Grade 5+ English & maths 2025/26 | 97.8 · 98 | 30% | 2.94 |
| Progress 8 2023/24 | 0.7 · 91 | 25% | 2.27 |
| Attainment 8 2025/26 | 71.4 · 97 | 10% | 0.97 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
Burnham Grammar School overview
How it's doing
In 2024/25, 94.4% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 70.1, compared to the national median of 44.6. Progress 8 was +0.7 in 2023/24, indicating better progress than pupils nationally starting from the same place. Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds, so they are not simply a reflection of who attends (9.4 out of 10 against similar schools, 9.5 out of 10 against all schools). Ofsted rated the school Good in January 2023.

What Ofsted said about Burnham Grammar School
Overview
Burnham Grammar School continues to be a good school, where pupils “enthusiastically embrace challenge and enjoy learning.” Leaders set high aspirations for all students, including those with special educational needs and/or disabilities, fostering an environment where relationships are “extremely positive” and behaviour is “exemplary.”
Strengths
- Pupils learn in “calm and purposeful lessons” due to high expectations and respectful conduct.
- Teachers possess “strong, and in many cases exceptional, subject knowledge” and effectively address misconceptions.
- The curriculum is “well sequenced” and prepares pupils for future study, with a broad sixth-form offer.
- Personal development is a strength, featuring a wide range of extra-curricular activities and effective careers guidance.
- Staff workload is managed well, with leaders providing support for professional development and subject expertise.
Areas to improve
- Leaders should ensure the curriculum is “implemented consistently across all subjects” to address variability in a very small number of areas where pupils do not achieve as highly as they could.
Safeguarding
The arrangements for safeguarding are effective, with leaders being “meticulous in how they protect pupils from risk of potential harm” and staff receiving timely training to respond to concerns.
