M-CHAT Autism Screening Tool

The M-CHAT™ (Modified Checklist for Autism in Toddlers) is a parent-report screening tool to assess the risk for Autism Spectrum Disorder (ASD). In approximately 10 minutes, parents can complete the 20 questions and receive an autism risk assessment for their child.

Age of Child: The M-CHAT is most appropriate for 16 to 30 month old children. If your child is 4 years of age or older, please visit our CAST page.

The primary goal of M-CHAT is to detect as many cases of ASD as possible (“maximizing sensitivity” in scientific parlance), so there will be some false-positives: cases where a child is assessed as being “at risk” but in fact will not be diagnosed with ASD. However, any child that receives a “high-risk” score should receive an evaluation from an autism specialist.

Action Behavior Centers have experts that can assist with your questions before, during, or after using the M-CHAT screening tool. Before you begin, please read the instructions immediately below!

Our M-CHAT autism screening tool is only meant to be the first step in a diagnostic process. A high risk score by itself does not mean your child will be diagnosed with autism. Our specialists will recommend an additional test (ADOS-2) which is a more thorough assessment involving face-to-face interaction with your child. Again, if your child is 3 years of age or older, the M-CHAT isn’t appropriate and our CAST might be helpful.
