A new program to prevent primary school absenteeism: Results of a pilot study in five schools,” published in Children and Youth Services Review, examined data from the The Early Truancy Prevention Project (ETPP), a program piloted in five North Carolina public schools.  According to researchers,

In 2013–14, the current version of ETPP was implemented in 20 classrooms in five high-poverty public elementary schools, with 21 other classrooms in the same schools serving as controls. Our analysis of attendance data indicated that ETPP significantly reduced the prevalence of absenteeism without excessively burdening teachers. Teachers reported improved communication between parents and teachers and had a positive assessment of the effects of specific program elements.

Attendance Works has additional information on the program and the study.
