This chapter focuses on skills that could maximize the effectiveness of an interventionist in developing social skills for individuals diagnosed with autism spectrum disorder. The nuance of social skills makes it an especially difficult curriculum to implement; therefore, it is important to understand best practices for teaching social skills as well as effective procedures to train these practices. This chapter describes various training procedures from discrete trial training to the teaching interaction procedure (TIP) and the benefits of each when it comes to staff training. It also includes a sample of how goals and teaching procedures might vary based on the interventionist’s current skill level. Supervisors and trainers should be aware of the benefits of each procedure, understand the current skills and goals of the interventionist, as well as have a good understanding of social skills to maximize interventionist’s and client’s progress. More importantly, the chapter describes the role of clinical judgment for both the supervisor and the interventionist.
