What it's Based On
Daily Attendance Records
(Pre-K to grade 12)
Whether students are marked as present or absent each day.
18+ Days Missed Per Year
Missing about 2 days each month (18+ days in a year) counts as chronic absence.
Why This Matters
Regular attendance is critical for learning. Students who miss too much school are more likely to fall behind in reading, have lower grades, and may be less likely to graduate.
- In Pre-K and early grades, chronic absence predicts future attendance problems.
- By 6th grade, it is one of three early signs a student may drop out later.
- By 9th grade, attendance is an even stronger predictor of graduation than 8th grade test scores.
What It Can & Cannot Tell You
It Can Tell You:
- Can show if large groups of students are missing too much school.
- Can highlight schools or grade levels where extra support may be needed.
It Cannot Tell You:
- Cannot explain why students are absent (health, transportation, safety, family needs).
- Is not the same as chronic truancy — this measure includes excused absences.
- High schools often have higher absence rates than elementary schools, so comparisons should be made at the school vs. network level, not school vs. district.
