How is the attendance score calculated?

Attendance score = (classes attended / total classes) × 100. For example, attending 40 of 45 classes gives an attendance score of 88.9%.

How does attendance weight affect my final grade?

The final grade is a weighted blend: (academic grade × academic weight%) + (attendance score × attendance weight%). So a 10% attendance weight means 90% of your grade comes from academic work and 10% from attendance.

What if my course has no attendance weight?

Set attendance weight to 0%. The tool will still show your attendance percentage, but it will have no impact on your calculated final grade.

Does this account for excused absences?

Enter only the absences that count against your attendance per your syllabus. Exclude any absences your instructor has formally excused.

Can I use this for partial attendance credit?

Yes. If your policy awards partial credit for arriving late (e.g. a tardy counts as 0.5 absences), enter the equivalent decimal number of absences.
