Instructions for Taking and Scoring the M-CHAT (available in other languages here)
A child should be referred for further evaluation when any three answers suggest risk for ASD, as indicated by the list of ASD risk responses that follow the questions.
Please answer questions to reflect your child’s usual behaviors. If the behavior is rare (e.g., you've seen it only once or twice), answer as if the child has not acquired the behavior.
