Frequently Asked Questions

The attendance rate is calculated as (Present + Late) ÷ (Present + Absent + Late) × 100%. Excused absences are excluded from the calculation entirely, meaning they don't count against the student's attendance record. A student with 8 presents, 1 late, 1 absent, and 2 excused would have a rate of (8+1)÷(8+1+1) = 90%.

However, clearing your browser cache or using private/incognito mode will remove the data. We recommend exporting your data regularly as a CSV backup.
