Who goes here

1561 pupils out of 1344 places At or near capacity

Pupils eligible for free school meals: 20
% eligible for free school meals: 2.0%
Pupil mix: 7 in 10 (similar to the Bexley average)
English as an additional language: 12% (England 22%)

Staff

Teachers leaving each year

Teacher turnover: 10.5% a year (Bexley 18.5%, typical in England 15.5%) Low turnover
Where they went: about 45% moved to another school, 55% left state schools altogether (retirement, other careers, independent schools, abroad)
Data years: 2022/23 to 2024/25 (average of 3 years, DfE school workforce census)

Teachers who moved school or left state schools in the year after each November, as a share of all the school's teachers. Some turnover is healthy – retirements, promotions, moving house. "Low turnover" means it's among the quarter of similar schools in England where teachers are most likely to stay.

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 Bexley: suspensions by reason

Suspensions for sexual misconduct: 21 (1.1 per 1,000 pupils; England 1.7)
Permanent exclusions for sexual misconduct: 1
Suspensions for bullying: 33 (1.7 per 1,000 pupils; England 1.9)
Suspensions for abuse against sexual orientation or gender identity: 6 (0.3 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 Bexley, 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: 3.8%
Persistently absent pupils: 4.9%
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

No dedicated Unit or Resourced Provision

SEN Unit and Resourced Provision

Most mainstream schools don't have a dedicated SEN Unit or Resourced Provision - it isn't a mark against a school that doesn't, just a different kind of setup than one that does.

Pupils on SEN Support: 0.6%
Pupils with an EHC Plan: 0.5%
Data year: 2025/26

Most common needs - SEN Support

Autistic spectrum disorder: 6 pupils
Speech, language and communications needs: 1 pupil
Vision impairment: 1 pupil
Multi-sensory impairment: 1 pupil

Most common needs - EHC Plan

Autistic spectrum disorder: 6 pupils
Social, emotional and mental health: 1 pupil
Speech, language and communications needs: 1 pupil

About these SEND figures

These figures give a sense of the makeup of the school - they aren't a judgement on the quality of support provided.

About this Ofsted rating

Ofsted changed how it rates schools in the last couple of years, so ratings from different years aren't always on the same scale - that's why we show the year alongside every rating.

Attainment 8 score: 75.6
Compared with the area: 23.8 points above the Bexley average (51.8)
Compared with schools with similar pupils: not compared – selective (grammar) school - chooses pupils by ability
Grade 4+ in English and maths: 100% (Bexley 72%, England 65%) Broadly steady
Data year: 2024/25

GCSE results over time

This schoolBexley averageEngland↗ Improving Up 2.6 points since 2022/23. In 2024/25 this school was 23.8 points above the Bexley average (51.8).

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.
