Abstract

Autism spectrum disorder can be reliably diagnosed prior to age 2, and early, intensive intervention has been found to improve long-term outcomes. Nonetheless, most children with ASD do not receive a diagnosis until after age 3, with even later diagnoses for children from non-white ethnic groups. This study conducted telephone surveys with California Part C early intervention managers regarding policies and practices for early identification and intervention for ASD. Findings indicated that 85% of agencies conduct screening for ASD, but only 39% conduct ASD diagnostic assessments prior to age 3. Recommendations for policy changes to align Part C practices with best practice guidelines are provided.
