This research study investigated the impact of implementing a Positive Behavior Interventions and Supports (PBIS) bus framework on student behavior. Pre and post-implementation data were collected from an elementary school (K-4) in a large suburban school district on Long Island. The school has been implementing PBIS school-wide but not a bus-specific framework. Office Discipline Referral data was collected and analyzed for All Students and Race and Gender. Data was further disaggregated by Race & Gender. School bus drivers were provided with training on PBIS and the use of the framework on the bus. This research serves to report the efficacy of a PBIS framework through a reduction of bus Office Discipline Referrals (ODRs). The study findings have implications for the implementation of PBIS-bus strategies and research concerning new ways to approach behavior management aboard school buses.
