Chertsey High School

Chertsey High School is an inclusive secondary school within the Bourne Education Trust. A full section 5 inspection took place in June 2026, and safeguarding standards are met. The school is particularly strong in attendance, behaviour, and personal development, while achievement, curriculum and teaching, inclusion, and leadership and governance are all at the expected standard. Pupils are polite, happy, ambitious, and feel safe; attendance is above the national average, persistent absence has fallen significantly, and low-level disruption is rare. The school's main strengths include a comprehensive personal development programme, effective careers education, a wide range of enrichment opportunities, and well-sequenced curriculum planning. Pupils generally achieve in line with national averages and move on to ambitious destinations. Support for pupils with SEND is well organised, governance is committed and provides effective challenge, and staff feel well supported in their professional development. The main concerns relate to disadvantaged pupils. Provision for disadvantaged pupils is not consistently highly effective, and some teaching adaptations are not precise enough to close gaps or address misconceptions quickly. In 2024/25, disadvantaged pupils' outcomes in English and maths and Attainment 8 were below national averages, and the disadvantage gap widened. The report's next steps focus on making disadvantaged provision highly effective and ensuring teachers adapt learning based on assessment so gaps in understanding are closed quickly.

Admissions: local authority offers data from the Department for Education. A school is oversubscribed when at least 5% of the families who put it first were not offered a place, and undersubscribed when everyone who put it first got in but 10% or more of its places were unfilled in the Department's school capacity survey (the latest survey is used for entry years it does not cover). Places: Department for Education, School capacity, from local authorities' annual survey as at 1 May. Each year is the one the school year ends in (2025 is 2024–25); the survey was not run in 2020. Places include sixth form places. Forecasts are the local authority's own for the school's planning area, an area it uses to plan places that is not the school's catchment area. The forecast starts from a head count in 2025; the dashed line is the Department's estimate of places in that area, including those the authority has firm plans for. Planned places are cumulative, and only those with firm plans are counted.

In 2024–25 pupils at Chertsey High School attended 93.0% of sessions (the national figure for secondary schools was 91.6%). 17.7% of pupils were persistently absent, missing at least one session in ten (nationally 23.4%).

Sessions missed

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.

In 2024–25, 6.6% of pupils at Chertsey High School were suspended at least once (nationally 7.3%). One pupil was permanently excluded.

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 Chertsey High School had 15.5 pupils for each teacher (the national figure for secondary schools was 16.7). Of its teachers in 2024–25, 25.2% were no longer at the school a year later (nationally 14.1%).

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, 13.7% of pupils at Chertsey High School were on SEN support (nationally 14.1%) and 4.6% had an education, health and care (EHC) plan (nationally 3.5%).

Pupils by main type of need

Source: Department for Education, Special educational needs in England (the 2025–26 school census). SEN support is extra help in school without an EHC plan. National figures are for all state-funded secondary schools. Counts are as published, with small numbers not hidden.

Academy figures include a share of the trust's central services, shared out by pupil numbers, and are rounded to the nearest £1,000. Premises costs were defined differently from 2024, so compare them across that gap with care.
