Direct answer
The Early Start Denver Model (ESDM) is a naturalistic, play-based early intervention for autistic children aged 12 months to 5 years. ESDM combines ABA learning principles with a child-centred, relationship-based approach. Strong RCT evidence (Rogers et al., Pediatrics 2010). ESDM is OAP-eligible when included in a funded Core Clinical Services plan. Find certified providers through the UC Davis MIND Institute registry at earlystart.ucdavis.edu.

The Early Start Denver Model (ESDM) was developed by Dr. Sally Rogers and Dr. Geraldine Dawson at the UC Davis MIND Institute. It is designed for children from 12 months to 5 years and blends Applied Behaviour Analysis learning principles with a child-centred, relationship-based framework.
ESDM has one of the strongest early-intervention evidence records in autism research. Rogers et al. (2010), Pediatrics: Randomized controlled trial showing significant gains in IQ, language, and adaptive behaviour versus community intervention at age 2.
OAP Core Clinical Services fund evidence-based ABA approaches. ESDM qualifies. If your child's individualized funded plan includes ESDM, OAP will cover the service. Confirm delivery details with your <a href="/oap-funding-guide" class="text-blue-600 hover:underline font-medium">AccessOAP</a> service coordinator. Private ESDM costs are typically $80–$150 per hour. Intensive ESDM at 20+ hours per week reaches approximately $40,000–$80,000 per year out-of-pocket.

Sessions happen in natural settings — your home, a daycare, a park — rather than a clinical table setup. The therapist follows the child's lead in play while embedding communication, cognitive, and motor learning targets into enjoyable interactions.
Intensity matters: ESDM is most effective at 20+ hours per week for toddlers. Lower intensity (5-10 hours) is used in combination with parent coaching to extend learning into everyday routines.

Cochrane systematic reviews show positive findings for language and cognitive outcomes in toddlers. ESDM is classified as a well-established evidence-based practice. ASSACT recognition: Listed as an evidence-based practice by the Association for Science in Autism Treatment.
Most rigorous evidence applies to children under 5. Evidence for older children is more limited — other approaches may be better suited once a child is school-aged.

ESDM certification is issued by the UC Davis MIND Institute or their licensed trainers. Certification levels: Therapist, Senior Therapist, Supervisor, and Trainer. The official certified-provider directory is at earlystart.ucdavis.edu/esdm.html.
When evaluating a provider, ask: What level of ESDM certification do you hold? How many hours per week do you recommend for my child's age and profile? How do you involve parents in the program?
