Abstract
Public programs have been charged with implementation of evidence-based practices (EBPs) to improve outcomes for children with autism. However, research indicates that scale-up of EBPs poses challenges. This study identifies perceived variables linked to effective statewide scale-up of EBPs in special education by exploring implementation climate and leadership across special education organization types (e.g., schools, districts, and regional consortiums). A simultaneous QUAL + QUAN mixed methods design was employed with the primary function of convergence and triangulation. Data included focus groups with 30 special educators and a statewide survey completed by 656 school personnel. In general, perceptions of implementation climate and leadership are weak in special education organizations with strengths at regional levels focused on special education and increased challenges at the school and district levels. Implications for practice and future research are identified.
