Geographic Access to Registered Behavior Technicians among Children with Autism Spectrum Disorder.

Research has documented inequities in geographic access to board certified behavior analysts (BCBAs) among children with autism spectrum disorder (ASD). Unexplored is geographic access to registered behavior technicians (RBTs), the frontline ABA providers BCBAs supervise. In this study we examined county-level geographic access to RBTs in the United States, including change in their geographic distribution over time, the current distribution of RBTs related to the distribution of BCBAs, and the current distribution of RBTs as a function of children with ASD. The sample included all U.S. counties in all 50 states and the District of Columbia ( N = 3,138). County-level ASD/RBT ratios indicate that the number of children with ASD far exceed RBTs, and the geographic accessibility of RBTs appears to be superior to that of BCBAs.
