• ESDM - Early Start Denver Model

The Early Start Denver Model (ESDM) is a comprehensive, naturalistic developmental behavioral early intervention approach designed by Drs. Sally Rogers and Geraldine Dawson for children ages 12 to 60 months who are diagnosed with or at risk for autism spectrum disorder (ASD). The model uses the knowledge of how typical children develop and learn and the ways in which ASD affects early development in order to improve developmental outcomes for children with ASD. The goals of ESDM are to reduce the severity of ASD symptoms in young children and to accelerate children?s developmental rates in multiple domains, including cognitive, social-emotional, adaptive, and language skills. ESDM is a manualized intervention and is comprised of a curriculum, a set of teaching practices that are based on naturalistic developmental applied behavior analysis principles, and a fidelity measure.

ESDM is one of two early intervention methods that are considered by the Agency for Healthcare Research and Quality to be efficacious intervention methods. Efficacy was initially established in an NIH-funded randomized clinical trial with toddlers with ASD, which demonstrated that ESDM resulted in significantly improved cognitive, language, adaptive behavior, and social outcomes, as well as normalized brain responses to social stimuli. Several additional studies have demonstrated the efficacy and effectiveness of ESDM across a variety of formats, including intensive delivery, parent coaching, and preschool/daycare delivery.
