The Safe & Civil Schools Positive Behavioral Interventions and Supports (PBIS) Model is a multicomponent, multitiered, comprehensive approach to schoolwide improvement. Integrating applied behavior analysis, research on effective schools, and systems change management theory, the intervention is an application of positive behavior support (PBS), a set of strategies or procedures designed to improve behavior by employing positive and systematic techniques. The intervention focuses on guiding members of an entire school staff in developing a schoolwide environment that is safe, civil, and conducive to learning. One of the core features of the Safe & Civil Schools PBIS Model is its emphasis on staff communication, collaboration, and cohesion. The intervention provides tools and strategies to help educators in elementary, middle, and high schools establish proactive, positive (nonpunitive), and instructional schoolwide discipline policies, manage student misbehavior and foster student motivation, and create a positive and productive school climate. It also aims to boost teacher satisfaction, contributing to increased teacher retention, and to engage students in the educational process, increasing their connectedness to the school community.
