The summary report shows the wrong number of Catholic pupils.
Go to Tools | Statutory Returns Tools | Update CES Census Lookups. Under Pupil Lookups Related check the value for Catholic Religion. If this is set to an incorrect value, eg Christian, set it to the correct value and press ‘Save’. Return to the census and press ‘Save’ then ‘Create & validate’. If the lookup value is correct and the summary report still shows an incorrect figure, check whether any pupils have joined or left the school between the census date (18th January in England, 16th January in Wales) and the date that the census was completed.
