Information on the school workforce in England, including subjects taught in state funded secondary schools, is collected as part of the annual School Workforce Census each November. Information is published in the ‘School Workforce in England’ statistical publication, available at: https://explore-education-statistics.service.gov.uk/find-statistics/school-workforce-in-england. The total number of hours taught for each subject are available at: https://explore-education-statistics.service.gov.uk/data-tables/permalink/38de2951-c92c-46e4-39fb-08db371965b6. The proportion of those hours that were taught by teachers without a relevant A level or higher level qualification are available at: https://explore-education-statistics.service.gov.uk/data-tables/permalink/ee831a35-e304-4821-bb6a-08db371944c7. Timetabled teaching is reported for a typical week in November, as determined by the school. It does not cover an entire year of teaching. If there are variations in timetabling across the year, this is not covered in the data available to the Department. To reduce the burden during the COVID-19 pandemic, schools and Local Authorities were not required to provide information on teacher qualifications in the 2020 census. Data on the subject taught is only collected from secondary schools that use electronic timetabling software that can produce data in the format required. Data is then weighted to provide national totals. Breakdowns by Local Authority and parliamentary constituency are, therefore, not available.
