The Modified Checklist for Autism in Toddlers (M-CHAT) is a validated developmental screening tool for toddlers between 16 and 30 months of age. It is designed to identify children who may benefit from a more thorough developmental and autism evaluation.

This screening does not indicate the presence of Autism but should be used as a tool to inform of risk. The results of the M-Chat screening should be shared with your pediatrician and next steps should be determined including scheduling a formal diagnostic assessment.
