Rogers, Todd and Avi Feller. Working Paper, 2017. This study analyzed whether information sent home to caregivers of K-12 students could impact chronic absence. Carefully worded messages on postcards reminded parents of the importance of absences and of their ability to influence them, added information about students’ total absences, or added the number of absences among target students’ classmates. The first two messages reduced chronic absence by as much as 10 percent across all grade levels. But messages to parents about how their children’s absences compare with students in the same class had no impact. The research shows that simple reminders to caregivers can be a strong and low-cost starting point to engage families.
