Check Absence Patterns for Siblings

There is no set report on ScholarPack for this.

You could run an Attendance Report for the whole school (either % Attendance Between or the Custom Attendance Report, group by Students), and filter by surname (click in the title column header to filter).

This will only work for siblings with the same surname, as it will place their attendance figures together.

Alternatively you could set up a static group in Data Digger for siblings (names found by running the Siblings Report) and run the % Attendance Between report using this group.
