The issued main academic year 2024-25 (Year 8) sample contained 5,652 schools in total, which is 27% of those in the sample frame.
The following table presents a breakdown of the academic year 2024-25 (Year 8) sample by type of school.
In addition to the main issued sample, there were reserve schools in the sample, some of which were issued during the course of the year in response to shortfalls in particular local authorities, or because those schools opted into the survey.
Only the issued or opted in reserve sample schools are shown in the following table. If a reserve sample school opted in, the data were included in the national data.

The following table presents a breakdown of the issued main academic year 2024-25 (Year 8) sample by year group and term of original issue.
The number of year groups is uneven because independent schools include fewer infant year groups.
