As the demand increases for statistics and data to measure the impact of the COVID-19 pandemic, we have had to change our data gathering and release practices, focussing efforts on priority analysis and statistics.

General description
The data covers different aspects of the school workforce in Wales, using the data collected from the School Workforce Annual Census (SWAC).

Data collection and calculation
School's data are derived from the School Workforce Annual Census (SWAC) returns in November each year. The returns are completed by local authorities. The number of staff for schools that did not submit data was estimated using information from the Pupil Level Annual School Census (PLASC).

Users, uses and context
As SWAC is an individual level collection there may be instances where a workforce member is recorded against multiple roles within the same school or in multiple schools. For local authority staff headcount, as part of the linking and aggregation process, those teachers with more than one role (e.g. working part-time in two schools) have their information combined into one record for each local authority they appear in, recorded against the highest grade for that individual.
For Wales level headcount, the same rationale is applied where teachers with more than one role (e.g. working part-time in two schools) but in different local authorities have their information combined into one record, recorded against the highest grade for the individual.
For this reason, where information is published by local authority the sum of local authorities may not equal to the Wales figure published.

Rounding applied
Figures greater than 0 and less than 10 have been suppressed, and secondary suppression has been applied to avoid disclosure through subtraction.

Statistical quality
The information collected for 2019 has not undergone a formal final validation process. However, various stages of automated validation and sense-checking are built into the process to ensure a high quality of data to inform policy making.
