Mersea Island School

Mersea Island School is performing at a good level overall, demonstrating several strengths in its educational approach. Pupils are happy and motivated to learn, with positive attitudes towards their education. The school’s values are effectively integrated into daily life, and pupils feel safe and supported. There is a strong focus on an ambitious curriculum that takes advantage of the school's unique seaside location, and teachers are well-prepared to help students, including those with special educational needs and disabilities. While the curriculum has been thoughtfully designed and is engaging, it is acknowledged that some recent changes are still in the process of being fully established. This has led to some inconsistencies in pupils’ knowledge across certain subjects. However, the leadership team is actively working on embedding improvements and enhancing the overall educational outcomes for the students. This inspection is the first since the COVID-19 pandemic, and the context has been considered in the evaluation of the school's performance.

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 Mersea Island School attended 96.0% of sessions (the national figure for primary schools was 94.8%). 10.1% of pupils were persistently absent, missing at least one session in ten (nationally 13.0%).

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, 0.0% of pupils at Mersea Island School were suspended at least once (nationally 1.1%). No pupils were 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 Mersea Island School had 21.4 pupils for each teacher (the national figure for primary schools was 20.7). Of its teachers in 2024–25, 21.4% were no longer at the school a year later (nationally 15.7%).

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, 16.2% of pupils at Mersea Island School were on SEN support (nationally 15.4%) and 3.6% had an education, health and care (EHC) plan (nationally 4.1%).

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 primary schools. Counts are as published, with small numbers not hidden.

In 2025–26 Mersea Island School received £6,642 and spent £6,537 for each of its 376 pupils. It ended the year with reserves of £75,000 (£198 per pupil).
