Suspensions Suspended: Do Changes to High School Suspension Policies Change Suspension Rates?

In recent years, the frequent use of suspensions and the racial disparities in their application, particularly for nonviolent behaviors, has created a maelstrom of public pressure for schools to adjust their suspension practices. In an era of increasing institutional accountability for schools, there is evidence that schools may be responsive to policy shifts when they are under institutional pressure to do so. Several school districts have recently revised their out-of-school suspension policies, but researchers know little about (a) if these changes in policy actually change students’ odds of suspension and (b) if so, how these changes might shift racial disproportionality in suspensions. This analysis examines the recent removal of suspensions for low-level infractions from the formal school discipline policy of a large, urban district. I use student-level data to compare the frequency and disproportionality of suspensions before and after the discipline code change. Findings suggest that although suspension rates decrease overall, multiple suspensions per student are more likely. With regard to disproportionality, black girls and white boys are more likely than expected to receive a first suspension in the post period as well. These findings highlight the importance of exploring heterogeneity in outcomes resulting from potential unintended consequences of policy change.
