Check the area around this school
9th of 16 secondary schools in Bexley we can score. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to the 814 schools whose pupils have similar backgrounds — a tougher field — and it places 2.0/10 among them, against 4.5/10 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 | 43.9 · 47 | 46% | 2.17 |
| Progress 8 2023/24 | -0.14 · 39 | 38% | 1.50 |
| Attainment 8 2025/26 | 46.2 · 52 | 15% | 0.79 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
