While the statewide trends and disparities suggest that the rate of lost instruction in California due to out-of-school suspension (OSS) is about where it was before the COVID-19 school closures, this is the first report to highlight how post-COVID suspensions in 2021-2022 have added to the pandemic's harmful impact of instructional loss, especially for students from "high-needs" groups, who were most harmed by the pandemic. This report analyzes California Department of Education (CDE) data sources to provide a detailed review of how suspensions directly contribute to disparities in learning opportunities for students in foster care or experiencing homelessness, as well as along the lines of race and disability in every California school district. It also describes evidence of extreme differences in how some districts responded to student misconduct in 2021--2022 and uses the data on student enrollment and the raw count of days lost due to OSS to establish a baseline measure for calculating comparable rates of lost instruction for every group in every district in California.
