ABSTRACT
This chapter offers an overview of the thinking and ideas that taken together constitute the roots of positive behavior support (PBS) systems. PBS relies upon an integration of behavioral and educational principles that have a demonstrated utility in allowing educators, parents, and helping professionals to understand individual behavior. The chapter also offers more than a review of existing PBS practice and describes a crucial third pillar to PBS systems, systematic program evaluation. It presents an overview of the historic and current research supporting the methodologies to provide effective intervention to student populations, monitor the effectiveness of the individual and group interventions, and provide ongoing schoolwide assessment of the effectiveness of PBS systems.
