From the abstract: "There is a continued call for the use of practices supported by evidence to improve the quality and effectiveness of services provided for students with disabilities. Despite best intentions, our education systems continue to struggle to adopt these practices and transfer them into consistent, sustained use by practitioners. Implementation science, the multi-disciplinary study of methods and strategies to promote use of research findings in practice, seeks to address this by providing frameworks to guide creation of conditions that facilitate use of evidence-based practices. The present article describes how an implementation science approach, Active Implementation Frameworks, was used by a national technical assistance center to cultivate systemic change and create improved outcomes for students with disabilities within several state, regional, and local education agencies. A summary of the lessons learned thus far and resulting considerations for practice and policy are presented. A key lesson was that state education agencies (SEAs) supporting districts and schools in implementation of a specific, educator-student-level practice realized improved outcomes for their students with disabilities. SEAs implementing frameworks or processes without an operationalized and measurable educator-student level practice had limited or no evidence of improved student outcomes."
