"The National Clearinghouse on Autism Evidence and Practice (NCAEP) conducted the third iteration of a systematic review that examined the autism intervention literature, extending the coverage to articles published between 1990 and 2017. This report describes a set of practices that have clear evidence of positive effects with autistic children and youth. The intervention practices examined had to be behavioral, clinical, developmental, and/or educational in nature. We also provide information about the study designs, participant characteristics, associated outcomes and implementation characteristics of the interventions."
