Check the area around this school
19th of 28 secondary schools in Barnet we can score. Local and same-phase on purpose: a national table mostly measures who attends.
Narrow the comparison to schools whose pupils have similar backgrounds and it does better still — 9.3/10 against 855 of them, against 8.3/10 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 |
|---|---|---|---|
| Grade 5+ English & maths 2025/26 | 60.8 · 82 | 45% | 3.71 |
| Ofsted | 52 | 40% | 2.10 |
| Attainment 8 2025/26 | 54.5 · 84 | 15% | 1.26 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
