Question - How do I resolve query 2520Q?
Answer - This query indicates thats attendance marks have been input for more sessions than the school is open for. This could mean that there are attendance codes in the holidays, to check this contact firstname.lastname@example.org who will advise you of the dates where codes have been entered. If you confirm that these are holidays they can be removed for you.
You could also be receiving this query if the term is unusually long. If this is the case you can annotate this query when uploading the census to collect.
