Question - How can I get a simple list of student persistent absences?
Answer - Go to Reporting>Reports>Attendance and choose Custom Attendance Report.
Select date range, sessions(s), "student" from the "Group Students By" option on the far right and set your threshold attendance percentage. Click choose to run the report.
Next, to get the report with student names, enter a value of 1 in the white box under the "count" header and press enter. This will filter the report to show only those with persistent absences.
