"Nth highest of N" counts the schools of the same type in the same school year that have a figure, with the highest figure first. It says where a figure sits, not whether it is good: for absence and suspensions lower is usually better, while free school meals and special needs reflect who the school serves. Where other schools have exactly the same figure the position is called "joint" and the number of schools with that figure is given. A dash means no position is held, because only one school has a figure or every school has the same figure.

Figures: the yearly series on this page. Positions: open schools in England, built 2026-10-27 from the DfE releases held by WhatSchool (school census, absence, exclusions, workforce, key stage 2 and 4), Open Government Licence v3.0. Ofsted dates: Ofsted management information, as at 30 September 2026. DfE has not published key stage 2 progress since 2022/23, so each progress measure has one year.
Attendance and behaviour
iAbsence is the share of possible sessions (half days) missed, for full academic years (no 2019/20 figure is published). Pupils suspended at least once and permanent exclusions are shares of pupils; suspensions per 100 pupils counts every suspension. 2020/21 and 2021/22 were affected by COVID-19.Overall absence7.4% 2024/25

iA dash means no published figure for that year. Each year is a school year, for example 2024/25 is September 2024 to August 2025.Yearly series held by WhatSchool from DfE school census, absence, exclusions, workforce, capacity and performance table releases. Series end at different years because DfE publishes them on different timetables. Latest-year values here can differ from the headline on another tab where DfE has revised a figure.Scroll sideways for more

Where this school sits in England
iEach figure is placed among state-funded secondary schools in England that report it for the same school year. "Higher than 70% of schools" means 70 in every 100 schools have a lower figure. This describes where a figure sits, not whether it is good: for absence and suspensions lower is usually better, while free school meals and special needs reflect who the school serves. It is not a ranking of the school.Scroll sideways for more
