The M-CHAT-R stands for the revised version of the “Modified Checklist for Autism in Toddlers.” It is a commonly employed developmental screening tool used to detect autism spectrum disorder in children aged 16 – 30 months. The survey consists of 20 questions that should take 5 – 10 minutes to complete.

“Developmental screening” is a general term to describe the practice of observing and tracking a child’s development. When monitoring a child’s progress, professionals look to multiple areas of development such as motor skills, cognitive and emotional development. Screenings helps professionals determine whether a more in-depth assessment is needed to confirm an official diagnosis.

The M-CHAT-R is not a diagnostic tool, but rather a screening tool used to guide parents and professionals to determine whether a more in-depth autism evaluation should be performed. A positive result on the M-CHAT-R does not necessarily mean a child has ASD, but rather it indicates a higher likelihood of ASD or a similar disorder.

After completing the questionnaire you will be given a score between 0 – 20. We will email your results with more information about your child’s unique score.

The following scale is used to determine a low-risk vs. moderate or high-risk of autism spectrum disorder:

Low-Risk: Total score is 0-2

Moderate-Risk: Total score is 3-7

High-Risk: Total score is 8-20

If your child scores between the moderate or high-risk zone, we’ll email you suggested next steps to get a more in-depth evaluation for your child.

If your child scores a low-risk, no immediate action is required. We advise that you retake the M-CHAT-R in 6 months as your child’s development progresses
