The Students > Attendance > Absentees > Broken Weeks report will show how many weeks of attendance have been broken due to absences. A broken week is a week where a student has received an absence mark for any roll call sessions during that week. This is useful to spot any regular patterns of absence.
The date range can be adjusted by clicking on the current date to view a period of your choice. You can also choose whether to show Authorised absences and Attendance not required marks along with Unauthorised absences - you can see more information on these codes here: Attendance codes and how they count towards statutory attendance
You can take various actions by first selecting students using the tick boxes, and clicking on the blue pencil. A list will appear with several options to choose from, including sending communications to Primary Guardians and creating an Intervention.
