  1. Teachers were counted once against each subject and key stage they taught, irrespective of the time spent teaching. Therefore teachers may be counted against multiple subjects and key stages so sums of these categories will be greater than the number of secondary school teachers.
  2. To reduce burden during the COVID-19 pandemic, schools and LAs were not required to provide information on teacher qualifications in the 2020 census.
