Sand Hill is a proud PBIS school. That sounds great, but what is PBIS? PBIS stands for Positive Behavior Interventions & Supports. It seeks to reduce or eliminate poor behavior school-wide through the encouragement of positive behaviors. PBIS decreases office discipline referrals, increases instructional time, and improves student achievement. This intentional focus on positive reinforcement is creating and maintaining a positive school climate for the students and teachers.
