Check the area around this school
3rd of 10 secondary schools in Windsor and Maidenhead we can score, 14 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 515 schools whose pupils have similar backgrounds — a tougher field — and it places 4.2/10 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 | 60.4 · 82 | 30% | 2.46 |
| Progress 8 2023/24 | 0.25 · 69 | 25% | 1.72 |
| Attainment 8 2025/26 | 53.2 · 81 | 10% | 0.81 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

What Ofsted said about Charters School
Overview
Charters School is described as an “exciting place to study” where pupils are “proud to attend” and feel safe. The report highlights that pupils “learn well” with access to a “wide range of opportunities” to develop their skills, supported by teachers who maintain “high expectations.”
Strengths
- Pupils achieve well across a broad range of subjects, with teachers using “skilful” methods to check understanding and identify gaps.
- Support for pupils with special educational needs and/or disabilities (SEND) has improved, ensuring they “learn well” and receive effective help to catch up.
- Sixth-form provision is particularly strong, with teachers using “impressive subject expertise” to inspire curiosity and providing extensive enrichment opportunities.
- Leaders and trustees demonstrate an “accurate understanding” of the school’s strengths and provide effective support and challenge.
- Behaviour in lessons is “calm and focused,” with off-task behaviour dealt with quickly to prevent disruption to learning.
Areas to improve
- Leaders should ensure staff are consistent in addressing behaviour that falls below expectations, particularly regarding “boisterous” breaktime conduct and a small minority of “defiant or disruptive” pupils.
- The recently improved personal, social, health and economic (PSHE) curriculum is not yet fully embedded; leaders should evaluate its impact to ensure learning builds consistently and addresses representation issues.
Safeguarding
The arrangements for safeguarding are “effective,” with staff receiving regular training and concerns reported promptly to secure timely help from external agencies when needed.
