Behaviour

Awaiting Data

About this Behaviour status

We've asked this school for real behaviour figures under Freedom of Information and haven't had a response yet.

Across Sutton: suspensions by reason

Suspensions for sexual misconduct: 28 (1.3 per 1,000 pupils; England 1.7)
Permanent exclusions for sexual misconduct: 0
Suspensions for bullying: 28 (1.3 per 1,000 pupils; England 1.9)
Suspensions for abuse against sexual orientation or gender identity: 12 (0.6 per 1,000 pupils; England 0.8)
Data year: 2024/25 (DfE suspensions and exclusions statistics)

These are figures for all state secondary schools in Sutton, not this school's own – the government doesn't publish them school by school. A suspension can have up to three reasons. Most sexual harassment between pupils never leads to a suspension, so these figures show only part of the picture.

Attendance

Overall absence: 5.9%
Persistently absent pupils: 11.8%
Data year: 2024/25

About persistent absence

A pupil is counted as "persistently absent" if they miss 10% or more of their possible school sessions - roughly one day in every two weeks. Schools and Ofsted both pay close attention to this figure specifically, since it can highlight a pattern the overall absence rate alone might hide.

SEN

Resourced provision for Autism 20 places · 22 pupils at the last count

Places are usually for children with an EHC Plan and are arranged through the council, not the normal school application.

Pupils on SEN Support: 8.4%
Pupils with an EHC Plan: 4.6%

Most common needs - SEN Support

Autistic spectrum disorder: 45 pupils

Educational Attainment

Ofsted report card January 2026

Ofsted's new report cards grade each part of school life separately, instead of giving one overall word.

Safeguarding Met
Inclusion Exceptional
Curriculum and teaching Strong standard
Achievement Strong standard
Attendance and behaviour Strong standard
Personal development and wellbeing Exceptional
Sixth form (post-16) Strong standard
Leadership and governance Strong standard

Before this, under the old system, Ofsted rated the school Good (2021). The report card above replaces that grade.

How Ofsted report cards work

Since November 2025, Ofsted grades each area of a school on its own five-point scale, and no longer gives a single word like “Good” or “Outstanding”. Safeguarding (keeping children safe) is simply met or not met.

Exceptional The very best practice nationally
Strong standard Above what Ofsted expects
Expected standard What Ofsted expects of every school
Needs attention Some weaknesses the school needs to fix
Urgent improvement Serious weaknesses needing urgent action

“Expected standard” is a sound result – it's what Ofsted expects a good school to do. Report cards aren't directly comparable with the old single grades, which is why we don't turn them into one.

Attainment 8 score: 61.6
Compared with the area: 2.2 points above the Sutton average (59.4)
Compared with schools with similar pupils: Well above (+11.7 points against an expected 49.9)
Grade 4+ in English and maths: 88% (Sutton 83%, England 65%) Broadly steady
Data year: 2024/25

GCSE results over time

This schoolSutton averageEngland→ Broadly steady No clear rise or fall since 2022/23 (changes this small are normal from one year group to the next). In 2024/25 this school was 2.2 points above the Sutton average (59.4).

About the Attainment 8 score

Attainment 8 measures a pupil's average result across 8 GCSE-equivalent qualifications (English and maths count double). It shows how pupils performed, not how much progress they made getting there - a school with a higher score doesn't necessarily add more value, since pupils often arrive with different starting points. Progress 8 is the measure designed to account for that, but it currently can't be calculated for any school for the two most recent academic years, due to a nationwide gap in the data caused by COVID-19 disruption to Key Stage 2 testing.

About leaver destinations

This shows where a school's Year 11 leavers were recorded the following year - in a "sustained" destination means in education, an apprenticeship, or employment for at least 6 months, not just enrolled briefly. It's a different picture from exam results alone, and can highlight schools that support pupils well beyond just their GCSE grades.

About this subject list

This isn't the school's own description of its curriculum - it's real DfE exam entry data, showing which GCSE subjects this school's pupils were actually entered for in 2024/25. A subject not appearing here may still be taught but had no pupils entered that year, so treat this as a helpful guide rather than a complete guarantee - it's worth confirming directly with the school for the year your child would actually study.

About this spending figure

A higher or lower position here isn't a sign of a better or worse school - schools have different needs and circumstances - but it can help reassure you that a school has sufficient funding behind your child's education.
