There are mandates in the field of special education that are now requiring “Evidence-Based Practices.” There have been over 150 published articles providing evidence of the effectiveness of the Picture Exchange Communication System (PECS). Highlighted below are organizations that recognize PECS as an Evidence-Based Practice along with peer review articles. See full list of research articles.
- In 2008, The National Professional Development Center (NPDC) on Autism Spectrum Disorder (ASD) adopted PECS as one of 27 Evidence-Based Practices. These practices are selected based on their efficacy proven through peer-reviewed research. NPDC is comprised of multiple universities that research and promote the use of Evidence-Based Practices on ASD.
- Research Autism is a charity dedicated to researching interventions in autism. Their website has a series of common interventions that are ranked based on “what scientific evidence has been published in peer-reviewed journals.” PECS has been given two ticks on their rating scale, indicating “strong positive evidence” for the quality of evidence supporting PECS as an intervention.

It is a straightforward and positive approach, cost effective and not overly time consuming to implement.
- Peer-Reviewed Research Review Articles have determined that PECS is evidence-based practice. One review published in the journal Preventing School Failure: Alternative Education for Children and Youth concluded that PECS is evidence-based practice for Communication, Socialization, and Behavior.
- The journal Pediatrics concluded that PECS is Evidence-Based Practice, as well as the only Evidence-Based Augmentative/Alternative Communication System, for individuals with autism spectrum disorders.
- Well-Controlled Research Reported in Peer-Reviewed Journals has shown that PECS is more effective than “education as usual” for improving communication and other skills in school settings.
- 150+ published articles providing evidence of the effectiveness of PECS.
- The co-developers, Andy Bondy and Lori Frost, continue to remain active in both research and writing. They have contributed to over 35 articles on PECS.
