Pupils persistently absent

Source: Department for Education, Pupil absence in schools in England. Each year is the one the school year ends in (2025 is 2024/25). Persistent absence means missing 10% or more of sessions; severe absence means 50% or more. No figures were published for 2019/20.

Pupils suspended at least once

Source: Department for Education, Suspensions and permanent exclusions in England. Each year is the one the school year ends in (2025 is 2024/25). A pupil can be suspended more than once, so suspensions per 100 pupils can be higher than the share of pupils suspended. Very small numbers are hidden by the DfE. Exclusion figures dropped in 2020 and 2021 because of school closures.

In 2025–26 Clarendon School had 5.6 pupils for each teacher (the national figure for special schools was 6.6). Of its teachers in 2024–25, 13.1% were no longer at the school a year later (nationally 14.5%).

Pupils per teacher

Teachers who left the school within a year

Source: Department for Education, School workforce in England. Each year is the one the school year ends in (2025 is 2024/25). Pupils per teacher counts full-time-equivalent pupils and teachers. Turnover is the share of a year's teachers (full-time equivalent) who were not at the school the following year, whether they moved to another school or left state-funded teaching. Turnover and sickness figures run one year behind the ratios. Sick leave is the share of teachers who took at least one day in the year, so it swings widely at small schools, where a few teachers can make it 0% or 100%. The national figures are for all state schools of the same type.

In 2025–26 Clarendon School had 164 pupils, 98.2% of them with an education, health and care (EHC) plan (nationally 99.5%).
