Statistical quality
The information collected from 2019 to 2023 have not undergone a formal final validation period. 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. A final validation period is being considered to be introduced for future collections for schools and LAs to review the information they return, and re-submit their data where errors are identified prior to publication.
