PBIS is a school-wide positive discipline plan. PBIS stands for Positive Behavioral Interventions & Supports. PBIS is an application of a behaviorally-based systems approach to create positive school environments by defining, teaching, and supporting appropriate student behaviors. PBIS improves the link between research-validated practices and teaching and learning environments. At Comer Elementary, we have chosen to focus on the “Three R’s—Respectful, Responsible, and Ready.” When students display these three expectations, their behavior is acknowledged with praise, rewards, and celebrations. PBIS encourages good behavior and increases instructional time.
