This study explores the impact of county-level immigration arrests on the academic achievement, attendance, and perceptions of school climate and safety for Latinx and Latinx English learner students in California's CORE districts. The research found that there is a negative relationship between immigration arrests and these students' academic performance and school experiences. The study recommends policies and practices that can help schools and districts create safer, more welcoming environments for immigrant-origin students and families in the face of anti-immigrant actions.

California and the US are undergoing a cultural shift in school accountability policies towards locally-determined measures of school performance. Lessons can be learned from the CORE districts, which developed an innovative accountability system, emphasizing support over sanctions, and utilizing multiple measures of school quality. The CORE districts' measurement system and collaboration hold promise for improving local systems, but efforts to build capacity remain a work in progress.
