5th of 38 primary schools in Harrow we can score, 40 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 3,204 schools whose pupils have similar backgrounds — a tougher field — and it places 8.2/10 among them, against 8.7/10 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 |
|---|---|---|---|
| Expected standard (RWM) 2024/25 | 87.0 · 96 | 40% | 3.82 |
| Ofsted | 96 | 35% | 3.37 |
| Higher standard (RWM) 2024/25 | 12.0 · 74 | 25% | 1.85 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
