M-CHAT-R Autism Screener

The Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) is a validated screening tool designed to identify children ages 16–30 months who may benefit from a diagnostic evaluation for autism spectrum disorder.

Before you begin:

  • This screener is designed for children between 16 and 30 months of age.
  • It takes approximately 5 minutes to complete.
  • Answer each question based on how your child usually behaves.
  • If your child has shown a behavior only once or twice, answer "No."
  • This is a screening tool, not a diagnosis. Results should be discussed with a healthcare provider.

The M-CHAT-R/F was developed by Diana Robins, PhD, Deborah Fein, PhD, and Marianne Barton, PhD. It is freely available for clinical, research, and educational purposes. This implementation is provided as a service to families and does not replace professional evaluation.
