5th of 99 secondary schools in Kent we can score, 103 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 115 schools whose pupils have similar backgrounds — a tougher field — and it places 5.9/10 among them, against 9.6/10 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% | 3.29 |
| Grade 5+ English & maths 2025/26 | 97.2 · 98 | 30% | 2.93 |
| Progress 8 2023/24 | 0.75 · 93 | 25% | 2.32 |
| Attainment 8 2025/26 | 77.0 · 99 | 10% | 0.99 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
