For over 20 years, the MESA Project (formerly Project PEAK) at the Oklahoma Autism Center (OAC) has provided consultation and professional development to educators and professionals who work with children with autism spectrum disorders (ASD). The OAC team brings together the combined experience of certified special education teachers, general education teachers, speech/language pathologists, occupational therapists, board certified behavior analysts, and psychologists. The goal is to build capacity in the public school system to support children with autism. This is done by teaching evidence-based practices through statewide trainings and workshops as well as through consultation with individual school teams.
