Clovis Unified began formally implementing Positive Behavioral Interventions and Supports (PBIS) in 2013. Starting with Gettysburg Elementary School, the program has grown to more than 20 CUSD schools. PBIS is an evidence-based three-tiered framework for improving and integrating all of the data, systems, and practices affecting student outcomes every day. It is a way to support everyone – especially students with disabilities – to create the kinds of schools where all students are successful.
