The Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) is a screener that will ask a series of 20 questions about your child’s behavior.
It is intended for toddlers between 16 and 30 months of age. The results will let you know if a further evaluation may be needed. You can use the results of the screener to discuss any concerns that you may have with your child’s healthcare provider.

Please answer each question to reflect your child's usual behaviors. If the behavior is rare (for example: you've seen it only once or twice), answer as if the child has not acquired the behavior.
