Schools are the portal through which many children with autism spectrum disorder access early intervention. Collaborating with teachers can be an effective way to implement evidence-based practices. In this study, teachers learned to embed strategies from the Joint Attention, Symbolic Play, Engagement, and Regulation intervention into the standard preschool curriculum. Twelve schools with special education preschool classrooms for students with moderate to severe disabilities from under-resourced neighborhoods were randomized to augment their curriculum with Joint Attention, Symbolic Play, Engagement, and Regulation strategies or continue the standard curriculum. Teachers’ strategy implementation, children’s time on task, and social communication were examined before and after completing the intervention phase. Teachers in the Joint Attention, Symbolic Play, Engagement, and Regulation group implemented more Joint Attention, Symbolic Play, Engagement, and Regulation strategies than the control group after the intervention phase. Children in both groups increased time on task during teacher-led small group instruction. Children in the Joint Attention, Symbolic Play, Engagement, and Regulation group were more likely to be engaged with peers during small group instruction at the end of the intervention phase. Children from both groups improved in standardized measures of joint attention, requesting, expressive language, and receptive language. Training teachers to embed Joint Attention, Symbolic Play, Engagement, and Regulation strategies into small group instruction can help facilitate peer engagement, providing children more opportunities for peer socialization. Lay abstract Children with autism spectrum disorder attending special education preschool classrooms may not receive support that addresses their core challenges, such as engagement and social communication. There are interventions designed to target these core challenges, like the play-based intervention known as Joint Attention, Symbolic Play, Engagement, and Regulation. Embedding strategies from an intervention like Joint Attention, Symbolic Play, Engagement, and Regulation into more traditional academic activities can help teachers target engagement and social communication throughout the school day. In the current study, we collaborated with special education preschool teachers to embed Joint Attention, Symbolic Play, Engagement, and Regulation strategies during small group time for moderate to severe disability students with autism spectrum disorder, 3–5 years of age. Compared to teachers implementing the standard preschool curriculum, teachers trained in Joint Attention, Symbolic Play, Engagement, and Regulation strategies effectively embedded these strategies in their small group activities, and their students were more likely to engage with peers during these activities. Supporting teachers to embed targeted strategies in academic activities can help them provide students more opportunities to engage with peers during the school day. Teachers can support their autistic students to interact appropriately with their peers. Unlike interventions that train peers to act as a teacher, embedding Joint Attention, Symbolic Play, Engagement, and Regulation strategies during small group academic activities facilitates naturalistic social interactions for autistic students.
