Question to the Department for Education:

To ask the Secretary of State for Education, what data his Department holds on the average class size at (a) primary and (b) secondary schools in (i) Great Yarmouth constituency and (ii) England in each of the last twenty years.

The department holds data on average class sizes in the ‘Schools, pupils and their characteristics’ publication, which is available here: https://explore-education-statistics.service.gov.uk/find-statistics/school-pupils-and-their-characteristics. This publication holds average class size at national level, local authority and school level. School level data from before 2010 is available here: https://www.gov.uk/government/publications/schools-pupil-and-their-characteristics-2002-to-2009-data.

Parliamentary constituencies are based on their boundaries at the time of the January school census each year. Therefore, the 2024 parliamentary boundaries do not reflect the changes made in the summer of 2024.

Where statistics were published prior to the changes in parliamentary constituency boundaries, they will be updated to reflect the new boundaries in the next publication of statistics. This is expected to be in June 2025 for the ‘Schools, pupils and their characteristics’ publication.

Class size data is published at school level. This can be combined with information from the Get Information About Schools (GIAS) website to identify parliamentary constituency, which is available here: https://get-information-schools.service.gov.uk/. GIAS currently reflects the changes made following the general election parliamentary constituency changes. Updates to geographical data are made on a quarterly basis using data published by the Office for National Statistics.
