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 Hounslow: suspensions by reason

Suspensions for sexual misconduct: 0 (0.0 per 1,000 pupils; England 0.2)
Permanent exclusions for sexual misconduct: 0
Suspensions for bullying: 2 (0.1 per 1,000 pupils; England 0.2)
Suspensions for abuse against sexual orientation or gender identity: 0 (0.0 per 1,000 pupils; England 0.0)
Data year: 2024/25 (DfE suspensions and exclusions statistics)

These are figures for all state primary schools in Hounslow, 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: 4.9%
Persistently absent pupils: 12.7%
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: 10.0%
Pupils with an EHC Plan: 1.0%
Data year: 2025/26

Most common needs - SEN Support

Social, emotional and mental health: 11 pupils
SEN support but no specialist assessment of type of need: 11 pupils
Speech, language and communications needs: 8 pupils
Autistic spectrum disorder: 7 pupils
Hearing impairment: 2 pupils

Most common needs - EHC Plan

Autistic spectrum disorder: 3 pupils
Social, emotional and mental health: 1 pupil

About this Ofsted rating

Year 6 SATs ranking

Junior and primary schools in this area, ranked by the % of Year 6 pupils meeting the expected standard in reading, writing and maths (official DfE results, 2024/25).
