8th of 15 secondary schools in Sutton we can score. 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 — 9.9/10 against 264 of them, against 9.9/10 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% | 1.83 |
| Grade 5+ English & maths 2025/26 | 100.0 · 100 | 30% | 3.01 |
| Progress 8 2023/24 | 1.16 · 99 | 25% | 2.48 |
| Attainment 8 2025/26 | 82.6 · 100 | 10% | 1.00 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
