What is the purpose of PBIS? (CT SERC, 2009)

The main focus of School-wide Positive Behavioral Interventions and Supports (PBIS) is to provide proactive and effective behavioral support for students at the universal level.

This is accomplished when the host environment (i.e., the whole school community) establishes and maintains universal procedures that contain clear and consistent behavioral expectations. Opportunities for student success are enhances by directly teaching universal expectations and establishing a school-wide system for reinforcing desired behavior. The necessary elements of School-wide PBIS include methods to: examine needs through data; develop, teach and reinforce school-wide expectations; discourage problem behaviors; and monitor implementation and progress.

SWPBIS is an application of behaviorally based systems approach to enhance the capacity of schools, families, and communities to design effective environments that improve the link between research-validated practices and the environments in which teaching and learning occur. Attention is focused on creating and sustaining primary (Tier 1), secondary (Tier 2) and tertiary (Tier 3) systems of support that improve lifestyle results (personal, health, social, family, work, etc.) for all children by making problem behavior less effective, efficient, and relevant, and desired behavior more functional.
