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

Educational Attainment

Outstanding 2023 report

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.

Educational attainment data for this school has not been added yet.

Attainment 8 score: 69.5
Data year: 2024/25

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.
