Tier I interventions are implemented on a school-wide or class-wide level and are intended to limit the development of problem behaviors. This chapter describes the preventive focus and emphasis on efficiency of these strategies, provides specific progress monitoring assessments, and introduces general issues related to classroom management. The approach of school-wide positive behavior interventions and supports (SWPBIS) is defined, and essential elements of systems, practices, data, outcomes, and building readiness are described. Next, class-wide PBIS procedures are discussed in terms of developing routines, rules, and expectations, acknowledgment of appropriate behaviors, and responding to problem behaviors. Finally, Tier I interventions in other educational settings (e.g., hallway, cafeteria) are discussed.
