Students with disabilities (SWDs) are disproportionately at-risk for bullying victimization and perpetration, yet there is a lack of educator-focused professional development targeting prevention for these students. This project sought to address gaps in training through the creation of four online professional development modules: (1) understanding bullying among SWDs; (2) examining risk characteristics; (3) establishing school and classroom prevention strategies; and (4) individual prevention. These modules were iteratively developed with feedback from teachers and staff, incorporating the Multi-Tiered System of Supports (MTSS) framework to focus on interventions rooted in social emotional learning (SEL), and emphasizing the importance of prevention for SWDs.?[This is the online version of an article published in "Education and Urban Society."]
