Check the area around this school
34th of 36 secondary schools in Buckinghamshire we can score, 37 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 — 0.9/10 against 686 of them, against 1.1/10 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 |
|---|---|---|---|
| Grade 5+ English & maths 2025/26 | 28.6 · 13 | 46% | 0.61 |
| Progress 8 2023/24 | -0.78 · 6 | 38% | 0.24 |
| Attainment 8 2025/26 | 38.7 · 14 | 15% | 0.22 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.
The Mandeville School overview
How it's doing
In 2024/25, 29.4% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 38.9, compared to the national median of 44.6. Progress 8 in 2023/24 was -0.78, indicating pupils did worse than nationally similar peers. Its results are much the same when the comparison narrows to schools whose pupils have similar backgrounds, so the gap is not explained by intake (1.1 out of 10 against similar schools, 1.2 out of 10 against all schools).
Beyond the classroom
A breakfast club is available for pupils.
Getting in
The published school roll is 966 pupils against a stated capacity of 1,001. 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 support pupils to close the gap between their current attainment and the national median? What specific interventions are in place for students with a negative Progress 8 score? How does the breakfast club integrate with the wider pastoral care for secondary students?
What Ofsted said about The Mandeville School
Overview
The report states that the school’s ambition for pupils has not been realised, particularly in key stages 3 and 4, where achievement has not improved quickly enough. Inspectors found that pupils have experienced a "poorly designed curriculum for too long," resulting in significant gaps in knowledge and skills. Consequently, many pupils, particularly the most disadvantaged, leave without the qualifications needed for future education or employment.
Strengths
- Pupils feel "happy and safe" and appreciate the new approach to promoting positive behaviour, with staff applying strategies "consistently well".
- Personal development is a priority, supported by a "coherent" PSHE curriculum that equips pupils with vital safety knowledge.
- The sixth form offers a "carefully designed programme" for BTEC qualifications, where students develop strong relationships with staff and achieve well.
- Teachers possess "strong subject knowledge" and generally present information clearly.
- Safeguarding arrangements are effective, and staff are positive about recent improvements and workload considerations.
Areas to improve
- The school must complete curriculum reviews urgently to ensure pupils gain a "secure body of knowledge" and address gaps in crucial subjects.
- Teachers must improve checks on learning to accurately identify and overcome gaps in pupils’ knowledge and misconceptions.
- Strategies to reduce persistent absence and eradicate in-school truancy must be reviewed to ensure attendance improves rapidly.
Safeguarding
The report states that "the arrangements for safeguarding are effective."
