Check the area around this school
2nd 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 127 schools whose pupils have similar backgrounds — a tougher field — and it places 7.1/10 among them, against 9.7/10 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 |
|---|---|---|---|
| Grade 5+ English & maths 2025/26 | 98.3 · 99 | 46% | 4.55 |
| Progress 8 2023/24 | 0.84 · 95 | 38% | 3.64 |
| Attainment 8 2025/26 | 75.6 · 98 | 15% | 1.51 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
