Attendance Rate vs Total School Days
How Attendance Rate is Calculated
Attendance rate measures the proportion of scheduled days a student was present.
Formula
Attendance Rate = Days Present / Total School Days x 100
Chronic Absenteeism
A student is considered chronically absent when their attendance drops below 90%, meaning they miss 10% or more of school days. Research consistently shows chronic absenteeism is one of the strongest predictors of academic failure.
Example Calculation
90 school days, student was present for 82, with 5 excused absences.
- 01Attendance rate: 82 / 90 x 100 = 91.1%
- 02Total absences: 90 - 82 = 8
- 03Unexcused: 8 - 5 = 3
- 04Below 90%? No (91.1% >= 90%)
