The M-CHAT-R (Modified Checklist for Autism in Toddlers, Revised) is a quick, parent-friendly screening designed for children 16 to 30 months old. It includes 20 simple questions focused on your child’s social interactions, communication, and play—important early indicators of autism.

A high-risk score doesn't mean your child has autism, but it may suggest the need for a more thorough evaluation. The M-CHAT-R is a helpful first step toward understanding your child’s developmental needs and exploring early support options.
