Abstract
As the use of school-based positive behavior support (PBS) spreads nationwide, the development of assessment strategies to identify intervention priorities becomes more critical. This study addresses the validity of the Effective Behavior Supports Survey (Lewis & Sugai, 1999) by examining reliability, determining whether rating differences exist across the four PBS systems and among schools, and reporting the use of the scale in schoolwide planning. Total scale internal consistency reliability reflects a moderate to high level, suggesting that the instrument does contain a cohesive set of items. A large effect size was also found differentiating ratings for the PBS systems, indicating that Individual Student Systems were considered least in place. A case example illustrating the use of the scale as a vehicle for collaborative action planning in a middle school is also discussed.
