Job coaches are not typically trained to implement systematic instructional strategies to teach vocational skills to students with intellectual and developmental disabilities (IDD). This study replicated and expanded the evaluation of a job coach behavioral skills training program designed by Brock et al. (2016) to teach participants to implement task analysis, simultaneous prompting, and system of least prompts to teach vocational tasks to students with IDD. We used a multiple probe design with probe conditions across strategies, replicated across three participants, to assess acquisition and generalization. Participants demonstrated mastery of the three instructional strategies in simulated assessments with actors and generalized use of the strategies to teach novel vocational tasks to student interns with IDD. Implications for future research and practice are discussed.
