Purpose: The purpose of this project is to develop and test the COMPASS \[Collaborative Model for Competence and Success\] Across Settings (CAST) intervention to enhance the goal setting and attainment skills of autistic youth. Despite federal education law mandating transition services as part of the Individualized Education Program (IEP) for ensuring good outcomes for students with disabilities, current educational practices have been unable to demonstrate that autistic students experience positive postsecondary outcomes. There are existing, evidence-based interventions aimed at supporting positive outcomes for these students. However, these interventions have not systematically provided coaching support to the caregivers, students, and employment specialists. To address these issues, CAST will integrate three evidence-based interventions for supporting student transitions while providing this critical coaching support. By doing so, CAST aims to align the priorities and goals of interventions across home, school, and community settings to better support positive postsecondary outcomes for autistic students.
