What is an indicator of high risk of Autism Spectrum Disorder according to M-CHAT?

A score of 8-20 on the M-CHAT (Modified Checklist for Autism in Toddlers) is considered an indicator of high risk for Autism Spectrum Disorder (ASD). The tool is designed to help identify children who may benefit from further evaluation for autism at a young age.

Children who score in this range are showing several concerning indicators that warrant additional assessment. This score suggests that the child is exhibiting a number of behaviors or responses that are atypical for their developmental stage, which could include issues with social engagement, communication, and repetitive behaviors. A score higher than 7 indicates a potential risk and prompts healthcare providers to consider referral for a comprehensive developmental and behavioral evaluation.

Lower scores—specifically those in the ranges of 0-2 or 3-7—indicate a lower risk for ASD or typical development, while scores of 21 or more are less common and would generally suggest very concerning levels of behavior that necessitate immediate intervention or support, but this category is not specifically defined in terms of typical risk indicators.
