Exploring Factors Across Levels Impacting Educators' Selection of Evidence-Based Practices for Autistic Students

Introduction: Front-line implementers report that selecting an evidence-based practice is the most challenging aspect of supporting Autistic students, which may contribute to the long-standing implementation gap. There is a need to understand educators' (special education teachers', general education teachers', and paraeducators') decision-making and determinants of their evidence-based practice (EBP) selection. Method: This study aimed to identify educators' decision-making factors, focusing on (a) information sources and (b) factors within the student, intervention, educator, and classroom levels. Eighty-one educators (general education teachers, special education teachers, and paraeducators) participated in semistructured interviews regarding their EBP selection for a specific student they served in inclusive classrooms. Results: General and special education teachers cited EBP sources from their teacher preparation and colleagues with autism expertise, while paraeducators relied on existing classroom practices and guidance from other educators. EBP decision-making frequently revolved around student and intervention characteristics, focusing less on educator, environment, and resource determinants. Educators made individualized EBP decisions for each student, selecting EBPs that served all students. They also shared that their decision-making was most supported through collaboration, despite limited opportunity. Conclusion: The study provides insights into key team members' EBP selection for Autistic students to aid in the development of implementation supports.
