PBIS is a school wide, proactive approach, which emphasises the instruction of social skills, data-based decision making, and the prevention of problematic behaviour. While fostering positive behaviours and interactions, PBIS also improves academic performance.
PBIS is an evidence based practice that enhances the capacity of schools to educate all students, especially children with challenging behaviours. It is a proactive system approach to school wide discipline that responds to the current social and / or educational challenges through three levels of intervention: universal, targeted-group, and individual intensive.
