Online M-CHAT-R autism screening tool

The Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) is a screening tool designed to identify children who may be at risk for autism spectrum disorder (ASD). The questionnaire consists of 20 yes/no questions that parents answer about their child's social, communication, and play behaviors.

The M-CHAT-R is most appropriate for toddlers. If your child is older, please visit our CAST screener.

Frequently asked questions

What is the goal of the M-CHAT-R?

The primary goal of the M-CHAT-R is to detect as many cases of ASD as possible. In scientific terms, this is known as “maximizing sensitivity.” This means the test tries to be very sensitive and identify the most amount of children who may benefit from early intervention. The M-CHAT-R might say a child is “at risk” even if they don’t have autism. However, this high sensitivity ensures children receive the help they need who might otherwise slip through the cracks.

Why is it important to identify autism early?

Identifying autism spectrum disorder in children early is important because it allows for timely access to early intensive behavioral interventions (EIBIs) like applied behavior analysis (ABA) therapy. ABA therapy has been proven to help children with autism improve their communication and social skills, prepare them for school, and reduce target behaviors.

Caregivers play a vital role in monitoring their child’s development and advocating for their child’s needs. Early autism detection, using tools like the M-CHAT-R and CAST, can significantly improve a child’s well-being.

What happens after I complete the M-CHAT-R?

After completing the M-CHAT-R, a Clinic Admissions Associate (CAA) will contact you within one business day. They will discuss what the next steps may look like for your family. Depending on your child’s score, they may recommend you schedule your child for the ADOS-2.

The ADOS-2 is a face-to-face assessment that can help your doctor evaluate whether your child meets the criteria for an autism diagnosis.

My child received a high-risk M-CHAT-R score. Now what?

If your child receives a high-risk M-CHAT-R score, it does not mean they have autism. Instead, it is a tool that helps identify children who may need further evaluation. The M-CHAT-R casts a wide net to ensure any child with potential ASD signs receives the support they need.

Please answer these questions about your child. Keep in mind how your child usually behaves. If you have seen your child engage in a behavior a few times, but they do not usually do it, then please answer no. Please check yes or no for every question.
