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 Hertfordshire: suspensions by reason

Suspensions for sexual misconduct: 33 (0.3 per 1,000 pupils; England 0.2)
Permanent exclusions for sexual misconduct: 0
Suspensions for bullying: 13 (0.1 per 1,000 pupils; England 0.2)
Suspensions for abuse against sexual orientation or gender identity: 3 (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 Hertfordshire (the council area this school is in), 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: 5.5%
Persistently absent pupils: 14.8%
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 AutismSpeech, language and communication 12 places · 6 pupils at the last count

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). Schools with the same result share a place (shown as =). In small schools one or two children can move a school several places, so treat close positions as roughly equal.
