Colchester Royal Grammar School
Colchester, CO3 3ND · Essex · Grammar school
4th of 78 secondary schools in Essex we can score, 81 in total — the rest without enough published data. 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 — 9.7/10 against 205 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 | 87 | 35% | 3.05 |
| Grade 5+ English & maths 2024/25 | 100.0 · 100 | 30% | 2.99 |
| Progress 8 2023/24 | 1.09 · 98 | 25% | 2.46 |
| Attainment 8 2024/25 | 82.1 · 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.

How it's doing. In 2024/25, 100.0% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 82.1, compared to the national median of 44.6. Progress 8 was +1.09 in 2023/24. Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds, so they are not simply a reflection of who attends (9.7 out of 10 against similar schools, 9.9 out of 10 against all schools). Ofsted rated the school Inadequate in April 2026.
Beyond the classroom. Pupils participate in Athletics, Cricket, Rugby, Football, and Netball.
Getting in. The school has 1059 pupils in a capacity of 777, meaning it is over capacity by 282. The school is over its stated capacity, so places are competitive.
Worth asking on a visit. How does the school plan to address the recent Inadequate Ofsted rating? What specific steps are being taken to improve provision following the inspection? How does the admissions process manage the current oversubscription?
