The problem of racial and ethnic discipline disproportionality is both long-standing and widespread. Educators must address this issue by identifying rates of discipline disproportionality, taking steps to reduce it, and monitoring the effects of intervention on disproportionality. The purpose of this guide is to provide a reference for School-Wide Positive Behavioral Interventions and Supports (SWPBIS) school teams in the use of discipline data (e.g., office discipline referrals, suspensions) in the area of racial and ethnic disproportionality in school discipline. The guide will describe a framework and steps for identifying levels of disproportionality, analyzing data to determine solutions, and monitoring the effectiveness of action plans in addressing disproportionality.
