Screening Tools


"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. The M-CHAT can be administered and scored as part of a well-child check-up, and also can be used by specialists or other professionals to screen for developmental delay and autism. We now offer M-CHAT online so that it is easier to use and score. This version features the latest scoring system, M-CHAT-R/F, developed by Dr. Diana Robins, Ph.D. et al., making the results more sensitive in detecting developmental concerns."

The Modified Checklist for Autism in Toddlers, Revised, with Follow-Up™ (M-CHAT-R/F) IS NOW AVAILABLE FOR FREE DOWNLOAD!!!

We strongly recommend that users switch to the new version, also known as M-CHAT-R/F. The revised tool reduces the false positive rate and detects more ASD cases than the original M-CHAT when used during routine pediatric check-ups. The M-CHAT-R/F is valid for children 16-30 months old.
