What is the threshold for chronic absenteeism?

Chronic absenteeism is officially defined (US Dept. of Education) as missing 10% or more of school days per year (18+ days in a 180-day school year) for any reason, including excused and unexcused absences. Chronic absenteeism affects approximately 16% of US students annually.

How does attendance in early grades affect later outcomes?

Research shows that chronically absent students in kindergarten and 1st grade are significantly more likely to struggle with reading by 3rd grade and to not graduate on time. The academic gap created by early chronic absenteeism is extremely difficult to close in later grades.
