This query will show if a student has any attendance before the entry date listed on the extended tab of their profile. You may need to correct this entry date if it does not show correctly, simply amend the date and click save at the bottom of the extended tab.
If this entry date is correct you can check the school history on the ancillary tab to confirm if the student previously attended your school and was readmitted. If this is the case the query will be accepted by DfE on condition that a suitable explanatory notepad entry is provided.
