Check the area around this school
5th of 78 secondary schools in Hertfordshire we can score, 82 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 285 schools whose pupils have similar backgrounds — a tougher field — and it places 6.2/10 among them, against 9.3/10 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 | 77.7 · 94 | 30% | 2.82 |
| Progress 8 2023/24 | 0.74 · 92 | 25% | 2.31 |
| Attainment 8 2025/26 | 65.0 · 95 | 10% | 0.95 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
