We publish evidenced-based language assessment and intervention materials for persons with autism or other intellectual disabilities.

Our publications are based on Applied Behavior Analysis (ABA) and B. F. Skinner’s (1957) analysis of Verbal Behavior (VB). Professionals and parents will find our assessment program, the VB-MAPP, to be a valuable tool for identifying a child’s specific language, learning, and social needs.

In addition, our book Teaching Language to Children with Autism or other Developmental Disabilities can guide professionals and parents through the process of implementing an evidence-based ABA/VB curriculum and intervention program.
