Free developmental screening
Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R™)
For toddlers 16–30 months old. Complete all 20 questions and receive the result immediately. Your individual screening answers are scored only in this browser and are not submitted or stored.
Instructions: Please answer these questions about your child. Keep in mind how your child usually behaves. If you have seen your child do the behavior a few times, but he or she does not usually do it, then please answer no. Please answer yes or no for every question.
This is a screening result, not a diagnosis. Discuss developmental concerns and appropriate follow-up with the child’s healthcare professional.
