This document summarizes a study that evaluated the impact of a professional learning course on supporting autistic learners in further education (FE) in Wales. The study collected data from teachers and lecturers who completed the Postgraduate Certificate in Autism course. It found that the course helped develop educators' understanding of supporting autistic learners, especially around transitions into and out of college. It also identified key areas of effective practice, such as learner participation and independence, as well as areas for improvement like appropriate learning spaces and student-centered support. Interviews further revealed that the course confirmed existing knowledge and understanding of differences for autistic learners, and that professional identities influence what is learned.
