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.
Narrow the comparison to the 188 schools whose pupils have similar backgrounds — a tougher field — and it places 9.3/10 among them, against 9.9/10 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 | 87 | 35% | 3.06 |
| Grade 5+ English & maths 2025/26 | 98.4 · 99 | 30% | 2.96 |
| Progress 8 2023/24 | 1.09 · 98 | 25% | 2.46 |
| Attainment 8 2025/26 | 80.9 · 100 | 10% | 0.99 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
Colchester Royal Grammar School overview
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, indicating better progress than pupils nationally starting from the same place. 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 inspected the school in April 2026 under the new framework, which grades areas separately without an overall grade.
Beyond the classroom
Pupils participate in athletics, cricket, rugby, football, and netball.
Getting in
The published school roll is 1,073 pupils against a stated capacity of 777. These whole-school figures do not establish entry-year vacancies or the likelihood of an offer. Confirm entry-year availability and admissions criteria with the school or local authority.
Worth asking on a visit
How does the school manage class sizes given the current roll exceeds capacity by 296? What specific support is available for pupils aiming to maintain their high attainment levels? How are the new Ofsted area grades reflected in day-to-day teaching practices?
