How Educators Use the Attendance Grade

  1. Enter total class sessions.
  2. Enter absences.
  3. View attendance grade.

Mathematical Logic

Divides days attended by total class sessions.

\text{Attendance (\%)} = \left( \frac{\text{Classes Attended}}{\text{Total Class Meetings}} \right) \times 100

Classroom Application Example

Scenario: 45 class meetings, 3 absences.

(42 / 45) * 100 = 93.3%

Result: 93.3% (A)
