This course is intended to provide an overview of both the principles that undergrid PBIS (Positive Behavioral Interventions and Supports) as a philosophy of practice and the practical applications of PBIS as a proactive approach in promoting optimal behavior across schoolwide, classroom, and individual levels. The reauthorization of IDEA in 2004 clearly mandates the use of PBIS as an evidence-based practice aimed at proactively addressing challenging behavior in students with disabilities. A central focus in this course is the application of this evidence-based practice with learners of all ages and abilities across learning environments, in particular students with Autism Spectrum Disorder.
