From the abstract: "Autism Focused Intervention Resources and Modules (AFIRM) are a set of self-paced, online learning modules designed to disseminate information about the 27 evidence-based practices identified through a large-scale review of focused intervention practices for individuals with autism. In this study, we used descriptive statistics and an analysis of variance to analyze more than 67,000 pre-tests completed by over 22,000 school-based AFIRM users to determine whether there are differences by occupation in the (a) selection of evidence-based practices, (b) knowledge of evidence-based practices, and (c) average number of evidence-based practices selected. Results reveal statistically significant differences between groups and have implications for providers and administrators responsible for designing and delivering professional development for school-based professionals working with students with autism."
