Check the area around this school
34th 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 685 schools whose pupils have similar backgrounds — a tougher field — and it places 5.9/10 among them, against 7.7/10 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 |
|---|---|---|---|
| Ofsted | 52 | 35% | 1.84 |
| Grade 5+ English & maths 2025/26 | 55.4 · 74 | 30% | 2.22 |
| Progress 8 2023/24 | 0.48 · 83 | 25% | 2.07 |
| Attainment 8 2025/26 | 50.6 · 72 | 10% | 0.72 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
