This report summarizes major points from the Center on Positive Behavioral Interventions and Supports' (PBIS Center) literature review on statewide behavior initiatives (SBIs) and findings from the PBIS Center's study that examined the extent to which SBIs have been developed and implemented. Of the 19 states that responded to the PBIS Center's study, 16 have SBIs that address all students, not just students with disabilities. Almost all SBIs place special emphasis on interventions for students with severe emotional disturbance, students atrisk for social or academic failure, and chronic offenders irrespective of disability status. One-third of respondents reported that SBIs have been implemented on a statewide basis. The majority of SBI behavioral objectives focus on classroom disruption and antisocial behavior, school violence, bullying, delinquency, and harassment. Strategies for addressing these objectives include behavioral management, classroom management, social skills training, academic accommodations, and early screening and intervention. Recommendations for state policy are provided and include ensuring participants from all stakeholders in the development and implementation of SBIs; providing financial support for SBIs by tapping a variety of funding sources; and providing professional development to school and agency personnel on interdisciplinary teaming.
