Defining characteristic of autism spectrum disorders are social impairments. Therefore, learners with ASD require direct intervention to increase their social skills used with peers and adults. Research has shown that peer mediated interventions and instruction (PMII) can be effectively used to increase the social interactions of learners with ASD with others. In this practice, typically developing peers are taught ways to interact with and support the social development of students with ASD. When implemented effectively, the quantity and quality of social interactions between students with ASD and their peers increases and can lead to more positive learning outcomes for students with ASD and their peers.
