Formula

Attendance (%) = (Classes Attended รท Total Classes Held) ร— 100

Status = OK if Attendance % โ‰ฅ Required %, otherwise Below requirement.

How it works

This calculator divides the number of classes attended by the total number of classes held and multiplies by 100 to obtain an attendance percentage. It then compares that percentage against the user-specified minimum requirement to display a pass/fail status. The tool assumes each class session counts equally and does not distinguish between excused and unexcused absences.

Worked example

  1. Classes attended = 36, Total classes held = 45, Required attendance = 75%.
  2. Attendance (%) = (36 รท 45) ร— 100 = 80%.
  3. 80% โ‰ฅ 75% required, so the status is OK.

Attendance: 80% โ€” Status: OK

Common mistakes to avoid

  • Dividing by classes scheduled for the whole term instead of classes actually held to date, understating attendance when some sessions have not yet occurred.
  • Counting a class as attended when only part of the session was attended, even though many policies require full-period presence to count.
  • Using the number of absences instead of the number of attendances in the numerator, producing 1 minus the correct answer.
