This query will arise if a dual registered student has attended all sessions the previous term at another school. In this case annotate the query on Collect when you upload the census file.
More commonly it will also arise when an off-rolled student has a leaving date after the end of previous academic year. In the example above, when you click on Fix Error, it will take you to the student profile's extended tab. Check the leaving date.
A student's leaving date ought to be the last day they have attendance data at the school, or the last day of the school academic year (if something prevented them attending and an alternative code was used for that period). Check the date to see that it complies with the above. If not, change the date. If you choose to keep this date, on Local Authority guidance, you will need to provide the reason when you upload the census file to Collect.
For the Spring Census 2021, attendance data is taken from the start of the autumn term (from 01-08-2020) to 31-12-2020 (p.111 in the DfE census guidance).
If the student's leaving date falls in August or early September prior to the start of your academic year, this query will therefore arise, as some attendance codes are expected with the student still on roll at that time. One way to remove this query is to change the leaving date to one in July 2020, within the previous academic year, then recalculate the census.
