Academic Harms of Missing High School and the Accuracy of Current Policy Thresholds: Analysis of Preregistered Administrative Data From a California School District

Currently, the state of California has dedicated much focus to reducing absenteeism in schools through the In School + On Track initiative, which revitalizes efforts made to keep accurate and informative attendance data. Additionally, absenteeism has been integrated into California’s Local Control and Accountability Plan to monitor district performance and improvement. Given the heightened policy concern surrounding absenteeism and truancy, this study seeks to improve researchers’ understanding of the impacts of missing school for high school students. This study will be the first known study to use preregistered secondary data from a school district, let alone the first preregistered study that seeks to address student attendance in schools.
