UnlockPlaces and pupil numbers
In 2024–25 Grendon Underwood School had 175 pupils for 210 places. 35 places (16.7%) were unfilled.
Reception intake in the “Waddesdon Primary” planning area
Buckinghamshire counted 106 Reception pupils in this area in 2024–25 and forecasts 111 in 2029–30, up 5%.
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 Grendon Underwood School attended 95.0% of sessions (the national figure for primary schools was 94.8%). 10.9% of pupils were persistently absent, missing at least one session in ten (nationally 13.0%).

| Authorised absence | 3.7% |
| Unauthorised absence | 1.3% |
| Severely absent pupils | 1.2% |
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, 3.3% of pupils at Grendon Underwood School were suspended at least once (nationally 1.1%). No pupils were permanently excluded.
Pupils suspended at least once
| 2025 | |
|---|---|
| Suspensions per 100 pupils | 10.4 |
| Permanent exclusions | 0 |
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 Grendon Underwood School had 21.0 pupils for each teacher (the national figure for primary schools was 20.7). Of its teachers in 2024–25, 11.1% were no longer at the school a year later (nationally 15.7%).

| Sick days per teacher | 2.5 | – |
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, 10.6% of pupils at Grendon Underwood School were on SEN support (nationally 15.4%) and 3.2% had an education, health and care (EHC) plan (nationally 4.1%).

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.
