Take a parent-completed questionnaire to tell if your child is meeting or falling behind on learning important skills during development such as waving "bye bye". This type of screening is recommended by pediatricians and can tell if your child is at risk for autism and/or developmental delay, in general.

M-CHAT Autism Screening Tool

The Modified Checklist for Autism in Toddlers (M-CHAT) is a pediatrician-recommended and validated questionnaire that parents can complete to identify any child who may be at risk for autism and who may benefit from a more thorough developmental and autism evaluation.

Why screen?

Screening may detect early signs of autism in toddlers, which is important for earlier diagnosis and treatment that have been shown to lead to better outcomes. The American Academy of Pediatrics (AAP) recommends that all children receive autism-specific screening at 18 and 24 months of age, in addition to broad developmental screening at 9, 18, and 24 months.

Who is M-CHAT for?

The M-CHAT screen is validated for use with all children between the ages of 16 months to 30 months. If your child is younger than 16 months or older than 30 months, and you have concerns about your child's development, start by consulting your child's primary care physician.

How valid are the results?

If your child receives a "Risk for Autism" result using the M-CHAT, studies show there is an over 90% chance he or she will be diagnosed with a form of developmental delay, including an almost 50% chance he or she will have a diagnosis of autism spectrum disorder.

What if my child’s result shows “Risk for Autism”?

It is recommended that you make an appointment with your doctor to review your child's M-CHAT findings and/or have a complete developmental assessment with a provider who is familiar with the process of diagnosing autism (usually called the Autism Diagnostic Observation Schedule or ADOS). Note: M-CHAT is only a screening tool to help identify children at risk for autism and does not replace a doctor’s diagnosis. If diagnosed with autism, it is important to consider early intervention and testing to identify an underlying genetic cause.
