High rates of absenteeism are often an early warning sign for negative long-term outcomes. Typical high school attendance policies, especially those that are punitive in nature, can make attendance problems worse. Fortunately, evidence suggests that even small improvements in student attendance can lead to meaningful outcomes. To support this recovery, high schools must have access to the most effective and efficient attendance interventions. The purpose of this systematic literature review is to summarize the current empirical research related to improving attendance in high schools. Results indicate that the 3 most common elements of high school attendance interventions with desired outcomes were skills training, family support, and incentive-based strategies. We discuss implications for future research and suggest that developing a continuum of research-supported practices within a multi-tiered system of support framework may be an effective way for schools to proactively and efficiently improve student attendance at the high school level.
