When Jackrabbit is set to track absences, you will find the Absences-Makeups report under the Students (menu) > Student Reports. Several filters are available to select which classes you want to look at.
Class Attendance in Staff Portal
The same situation is also used in the Attendance Report Help article to contrast the difference between tracking attendance vs tracking absences.
In this class, there are four students enrolled in the Ballet - Beg - F class. When attendance was taken in the Staff Portal there were three students present and one student absent.
The Absences-Makeups report for the class above looks like this. This student is eligible for a makeup class for the class she missed. The note created in the Staff Portal shows in the Note column.
