This presentation, from the Positive Behavior Support Special Interest Group, focuses onthe contributions of applied behavior analysis to positive behavior support. School-wide positive behavior support (SWPBS) is a decision making framework that guides selection, integration, and implementation of the best evidence-based academic and behavioral practices for improving important academic and behavior outcomes for all students. Almost 20,000 schools have adopted SW-PBS as an implementation framework based on the principles of applied behavior analysis across a multitiered system of support. Dr. Dunlap will review the implementation of school-wide positive behavior supports with treatment integrity in schools and its impact on academic success and behavior climate. Data on outcomes and the factors leading to successful implementation will be presented both in the domain of implementation integrity, but also regarding behavioral reduction outcomes school-wide. Using PBIS, a behavior analyst at a macro level can examine school-wide data to provide a functional examination leading to system level interventions that help prevent and reduce behavioral problems for a large number of students.
