The summary report shows the wrong number of pupils
SIMS extracts data for the Census date of 18th January 2024 in England and 16th January in Wales. If pupils have joined or left the school since that date then the census totals will be different to the totals on the day the census is completed.
If a pupil is dual registered and your school is their subsidiary school they will not be included in any part of the CES Census.
