Chronic Truancy Rate
This graph shows the percentage of students who miss 5 percent or more of school days per year without a valid excuse. Learn More
Illinois law defines “chronic truant” as a student who misses 5 percent of school days within an academic year without a valid excuse. That’s nine days of an average 180-day school year. The count of chronically truant students does not include students with excused absences. Chronic truants are at risk of academic and behavioral problems. Research shows that chronic truancy has been linked to serious delinquent activity in youth and to significant negative behavior and characteristics in adults.
