What is PBIS?

From https://www.pbis.org/pbis/what-is-pbis

Positive Behavioral Interventions and Supports (PBIS) is an evidence-based, tiered framework for supporting students’ behavioral, academic, social, emotional, and mental health. When implemented with fidelity, PBIS improves social-emotional competence, academic success, and school climate. It also improves teacher health and well-being. It is a way to create positive, predictable, equitable and safe learning environments where everyone thrives.  

Schools implementing PBIS:

PBIS is not a curriculum you purchase or something you learn during a one-day professional development training. It is an ongoing commitment to supporting students, educators, and families through systems change. When you implement PBIS well, students experience improved behavioral, social, emotional, and academic outcomes; schools and programs reduce their use of exclusionary discipline practices and improve their overall climate.
