What is NCAEP?

The National Clearinghouse on Autism Evidence and Practice (NCAEP) conducted a systematic review of the current intervention literature targeting individuals on the autism spectrum. NCAEP is a continuation of the evidence review that was completed by the National Professional Development Center on Autism Spectrum Disorders (NPDC) which included research published through 2011. We reviewed research studies publishedbetween 2012-2017 which examined the impact of behavioral, educational, clinical and developmental practices and service models used with individuals on the autism spectrum from birth through age 22. The literature is expanding rapidly so we hope to establish an active yearly review that will provide families, practitioners, and researchers with more timely updates. In the future, NCAEP hopes to expand this important work to identify EBPs for adults on the autism spectrum and to include pharmaceutical interventions. 


We conducted this review to help inform practice and policy, and to ensure that individuals with autism spectrum disorder are provided the most efficacious interventions that can lead to the most successful outcomes. We plan to use this information to create additional resources for educators, clinicians, families, health care providers, and researchers based on the updated findings.

When did NCAEP conduct their work?

We started the review process in 2017 and published the final report in April 2020. See a detailed timeline here.
