School-wide Positive Behavior Interventions and Supports (PBIS) is a systemic framework for addressing challenging behaviors within schools. The goal is to increase the academic and social behavior outcomes for all students. School-wide PBIS is the behavioral part of the Response to Intervention (RtI) triangle that is currently implemented in more than 10,000 US schools.
PBIS is not a "packaged curriculum" or geared toward "rewarding" students. Depending on the local culture and the needs of the school, school-wide PBIS plans adapt to fit the context and can look different across districts or even schools.
School-wide PBIS is a prevention-oriented approach to school-wide discipline. It is a framework that focuses on the use of evidence-based practices and solid, effective data-based decision-making to improve academic and social contexts. The three-tiered approach provides additional interventions for students as their behavioral / social needs increase.
