Positive Behavior Intervention and Support (PBIS) involves a proactive, comprehensive, systemic and individualized continuum of support designed to provide opportunities to all students to achieve social and learning success. The main focus of school-wide PBIS is to provide proactive and effective support regarding student behavior at the universal level. This is accomplished when the whole school community can establish and maintain universal procedures that contain clear and consistent expectations. There are greater opportunities for student success when students have clearly defined expectations that are taught and reinforced. School-wide PBIS, when implemented effectively, increases collaboration and communication among school personnel, families and the community, thus improving the quality of life for all students.
