The average age of diagnosis for autism spectrum disorder (ASD) for a child already identified as D/HH is later than that for a hearing child. Early assessment data (starting at 9 months) for three children who were D/HH and later diagnosed with ASD were analyzed. The results from the MacArthur-Bates CDI Words and Gestures, the Child Development Inventory, and the Play Assessment Questionnaire were used to develop three profiles of children who are D/HH and have ASD. One child lacked expected skills and language at ages 9 and 14 months. Another child lost skills and language after 17 months. The third child had results usually within or above the average range. However, his age quotients decreased for MacArthur-Bates CDI: WG Words Expressed and the CDI: Social. While it can be difficult to diagnose the co-occurrence of ASD and deafness, there were early warning signs for these children.
