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: 4.3%
Persistently absent pupils: 6.9%
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: 8.0%
Pupils with an EHC Plan: 4.4%
Data year: 2025/26

Most common needs - SEN Support

Social, emotional and mental health: 12 pupils
Speech, language and communications needs: 7 pupils
Other difficulty or disability: 6 pupils
Autistic spectrum disorder: 4 pupils

About this Ofsted rating

Ofsted stopped giving single overall grades for a period between September 2024 and November 2025 - this school's most recent inspection falls in that window, so there's no single rating to show, even though it was inspected. The full report (linked below) still has the detail.

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.
