The purpose of this research was to examine the level of School-wide Positive Behavior Support (SWPBS) implementation in the State of Florida. The relationship between implementation fidelity of SWPBS to academic and behavioral outcomes for elementary and middle schools was then analyzed. The results of this study found that SWPBS is being implemented with fidelity in the majority of schools in one year and that these schools maintain or increase fidelity over time. Findings also suggest that there may be a relationship between greater implementation fidelity and lower ODR and OSS rates and to a lesser extent, academic outcomes.
