Overall, students advanced their skills related to identifying extant scientific literature, choosing appropriate singlesubject design evaluation methods, and critically analysing the effects of attempted interventions. Students rated the course as having high social validity and predicted the course content would positively affect their professional practice.The relevance of the course and future directions are discussed in the context of meeting the global need for effective autism intervention professionals.
