M-CHAT-R Scoring Instructions

To score the M-CHAT-R, use this list of failed responses to compare the parents’ responses on the screener. The child receives one point for each failed response.

A child demonstrates Medium-Risk for ASD if the total score is 3-7 and a Follow-Up Interview should be performed. If a child’s total score is 8-20 points they are at High-Risk for ASD and a Follow-Up Interview can be performed to gain clarity on at-risk responses or you can skip this step and refer the child for a diagnostic evaluation and early intervention services. A total score of 0-2 means the child passed the screener and surveillance should continue at all subsequent health supervision visits.
