Use abbreviations for tardy, left early, absent
Right now, tardies and absences all look the same. Let's say a student comes late to school, that might be marked as 1L, or "late to first period". Then, that student is tardy, so 2T or "tardy to second period". Then, the student left early/was checked out, so 3LE or "left early from third". These designations would be helpful to teachers later in the day to see what was going on with the student, and to help a student if absences, tardies, or leaving early became a chronic problem. Adding L for late, T for tardy, or LE for left early beside the period number would be an easy at-a-glance way to better monitor student attendance.

Due to screen limitations, several attendance statuses, reason codes and time in/out cannot be accommodated.
