The M-CHAT, or Modified Checklist for Autism in Toddlers, is a quick and widely-used questionnaire to screen for autism in toddlers. It has 23 yes-or-no questions about your child’s behavior and development, covering communication, social interaction, and repetitive behaviors. While it’s not a diagnostic tool, the results can help identify children who may need further evaluation for autism. Parents and caregivers can use it to seek early intervention and support if necessary. For those with special needs kids, fathers of older children with developmental delays, special ed teachers, speech-language pathologists, or autistic adults, understanding the M-CHAT can be crucial in spotting potential developmental issues and finding appropriate support and services.
