PACE research is prominently featured in the repository on chronic absenteeism established by the California Collaborative for Educational Excellence (CCEE). The collaborative serves as a valuable resource hub, offering toolkits, materials, and various other assets related to chronic absenteeism in educational settings. PACE's contribution to this repository includes two research briefs focusing on chronic absenteeism. The first brief involves PACE's in-depth analysis of student chronic absenteeism data from the CORE Districts, exploring the utilization of chronic absence metrics within a multi-metric accountability system. The second brief delves into the chronic absence performance levels of California's districts, schools, and student groups, utilizing recently released data from California's School Dashboard. This brief also investigates the pivotal role played by chronic absence in determining differentiated assistance, providing insights into the impact on school performance. Together, these research briefs offer valuable perspectives and data-driven insights into addressing and understanding chronic absenteeism in the context of California's educational landscape.
