As part of the Welsh Local Government Finance Settlement, the data is usually returned to local authorities for final validation. Typically, overall numbers of pupils and teachers will not change significantly during this period, with the most likely change being in the characteristics of the pupils themselves e.g. free school meal entitlement. Users should therefore be more cautious when comparing data on characteristics of pupils and staff over time, in particular where small cohorts are involved.Click here to sort2020/21The schools census would usually take place in January. School closures between December 2020 and March 2021 due to the coronavirus (COVID-19) pandemic meant that the census date was delayed to 20 April 2021. The number of pupils was higher in April 2021 partly due to the later census date which meant that more pupils had entered nursery classes by the census date.Click here to sort2021/22The schools census would usually take place in January.
