Every absence, excused or unexcused, is a learning opportunity lost and can have significant impacts on a student’s success in school and life. A student who misses 10% or more of their school days, which amounts to 18 or more days in a school year—or just two days a month—for any reason is considered chronically absent. Chronically absent students are more likely to fall behind in reading and math and less likely to graduate from high school. Addressing chronic absenteeism and developing good attendance habits is a solvable problem for which we all share responsibility.
