Young children with autism spectrum disorder (ASD) require supports and services designed to meet their unique needs. Research has identified 27 evidence-based practices (EBPs) for children ages birth to 5 years. However, there is a paucity of research that examines whether early childhood providers are implementing EBPs with children with ASD. In this study we determined the levels of training, confidence, and frequency of EBP implementation by U.S.-based early childhood providers, including early childhood educators and early intervention providers. These findings indicate gaps in both knowledge and implementation of EBPs. Implications for research and practice are discussed.
