M-CHAT (Modified Checklist for Autism in Toddlers)

The M-CHAT (Modified Checklist for Autism in Toddlers) is a screening tool used by healthcare providers to identify young children at risk for autism spectrum disorder (ASD). It consists of a series of questions for parents about their child's behaviors and development, typically around 18-24 months old. The purpose is to detect early signs of autism so that children can receive timely evaluation and support if needed. While it does not diagnose autism, it helps flag children who may benefit from further assessment by specialists.
