Frequently asked questions

How is an attendance percentage calculated?+

Divide the number of classes attended by the total number of classes held, then multiply by 100: Attendance % = (Classes attended / Total classes) x 100.

How many classes can I miss and still meet an 80% attendance requirement?+

It depends on the total number of sessions in the term — for a course meeting 30 times, 80% attendance means attending at least 24 sessions, so up to 6 absences are allowed. Divide the total sessions by 5 to quickly estimate the 20%-absence allowance.

Does an excused absence usually count against attendance percentage?+

This varies by institution and course policy — some count excused absences as attended for calculation purposes, others exclude them from the total class count entirely, and some count them as absences regardless of the reason. Check your syllabus.

Why do some courses set a minimum attendance threshold at all?+

Attendance often correlates strongly with performance and participation, so many institutions and instructors use minimum thresholds (like 75-80%) as an academic requirement, sometimes tied directly to eligibility for a passing grade or final exam.

How do late arrivals or early departures factor into attendance tracking?+

Policies vary widely — some courses count partial attendance as a fraction of a full session, others treat a late arrival past a certain point as a full absence. This detail isn't part of the basic percentage formula and should be clarified with your instructor.
