The Department does not hold COVID-19 testing data.
We collect data on the open status of schools, the number of schools that have indicated they have sent children home due to COVID-19 containment, and the total number of pupils reported absent due to a confirmed COVID-19 case. The data is published from this collection at a national level as part of the official statistics series. The publication can be found here: https://explore-education-statistics.service.gov.uk/find-statistics/attendance-in-education-and-early-years-settings-during-the-coronavirus-covid-19-outbreak.
On 19 November 2020, 18,000 pupils in state-funded schools were reported absent due to a confirmed case of COVID-19. This data is collected at school level, not pupil level. Therefore, we cannot estimate a total for the number of pupils absent since the beginning of term.
Please note that Public Health England (PHE) leads in holding data on infection, incidence, and COVID-19 cases overall. PHE publishes data on COVID-19 incidents by institution, including educational settings, which can be found through the following link: https://www.gov.uk/government/publications/national-covid-19-surveillance-report.
