This Information Capsule reviews the research conducted on outcomes associated with placing students with Autism Spectrum Disorder (ASD) in inclusive classrooms. Key findings include: (1) studies comparing the academic and social outcomes of students with ASD placed in inclusive versus segregated special education classrooms have produced mixed results; (2) research conducted on the impact of inclusive classrooms on nondisabled students' academic and social outcomes has produced inconsistent findings; (3) inclusion works for some but not all students with ASD; (4) physical integration of students with ASD and nondisabled students in inclusive classrooms alone may not be enough to produce positive outcomes; and (5) the biggest challenge is providing teachers with enough training and support.
