What is M-CHAT autism test?

The M-CHAT is a reliable test used to detect early signs of autism spectrum disorder (ASD) in children aged 18-30 months old. It consists of 20 questions about the child's behavior, language, and social interaction skills with a sensitivity rate of up to 90%.


The American Academy of Pediatrics recommends that all children receive an initial screening with the M-CHAT at 18 months old.


Why is it worth taking The M-CHAT Autism Test online?

While this quiz is not a diagnosis of Autism, the test can indicate whether your child has the signs of Autism. If they score highly on this autism test, you should speak to your child's doctor about arranging a formal diagnosis. 



This Autism Spectrum self assessment is delivered to you free of charge.


Early detection.

The average age of diagnosis for autism spectrum disorder (ASD) is 4 years. With the help of M-CHAT, it may be possible to diagnose ASD at a younger age - paving the way for earlier intervention strategies that lead to dramatically better long-term outcomes. 

Intervention should start when an Autism diagnosis is suspected, rather than when a formal diagnosis is made.


Clinically validated.

The M-CHAT has been extensively studied and tested in clinics worldwide to assess its accuracy in detecting signs of ASD.


M-CHAT screening tool has a high degree of accuracy compared to other screening methods and is recommended by the American Academy of Pediatrics.


Reduce unnecessary referrals.

The use of the MCHAT also improves communication between parents and healthcare providers and allows families to address any issues more quickly without referrals to subspecialists.


Made by professionals.

The M-CHAT autism screening test was developed by Dr. Robert L. Hendren and Dr. Marianne Barton at the University of California, Davis Medical Center.


Since then, several other researchers at the Autism Research Program have improved the test. The M-CHAT is now used around the world as a reliable tool for identifying autism spectrum disorder (ASD).


Early intervention services.

When diagnosed young, children have a better chance of developing skills necessary for healthy social interactions and independent living later in life.

What Parents Say

"We were starting to question our son's development. The app really gave us the courage to speak up more boldly for our son to get early intervention."

A high score on the M-CHAT-R test results indicates concern, not diagnosis.

It is important to remember that this test is only one part of the diagnostic process, and it does not definitively diagnose ASD but indicates whether further investigations are necessary.


The test consists of 20 questions that measure how the child reacts to and interacts with certain objects, people and situations. The answers are scored on a scale from 0 to 20.

  • Total Score 0-2 indicates a low risk of Autism.

  • Total Score 3-7 suggests that more in-depth review is needed.

  • Total Score 8-20 indicates a high risk of Autism and requires further evaluation with a child's healthcare provider.


What are the best Autism tests?

The most popular autism tests recommended by the American Academy of Pediatrics is the M-CHAT (Modified Checklist for Autism in Toddlers).


It has high sensitivity and specificity, meaning it can accurately identify those with ASD while minimizing false positives.


Developed by Dr. Robert L Schroth and Maria A Rutter, it has been validated by numerous research studies.


While it should not be used as a stand-alone tool for diagnosis, it can provide essential insight into a child's development. It can then be combined with other assessments to make an informed decision regarding diagnosis and treatment options.

Another benefit of using the M-CHAT screening tool is its ease of administration. Unlike more involved tests such as the Autism Diagnostic Observation Schedule (ADOS) or the Autism Diagnostic Interview–Revised (ADI–R), the M-CHAT is simple enough for parents or carers to complete at home without extensive training or specialist equipment.

What is M-Chat R/F used for?

The screening test consists of 20 questions about your child in different areas, such as play skills, communication, social interaction, and other developmental milestones.

If the parent answers "yes" to any of the questions or has concerns about their child's development based on the responses, they are recommended to complete additional follow-up questions. The follow-up interview aims to clarify potential warning signs and capture more detailed information about your child that the initial questionnaire may not have caught.

When administered correctly and with appropriate follow-up interviews, it can help identify possible signs of ASD that might otherwise be overlooked or dismissed. This allows parents, teachers, and healthcare providers to get an accurate picture of a child's functioning and helps guide decisions on how best to support their overall well-being.

What are the 3 main symptoms of Autism spectrum disorder?

Autism spectrum disorder (ASD) is one of the most common developmental disorders characterized by difficulty with communication, social interaction, and repetitive behaviors.


The three main symptoms are:

  • impaired social communication and interaction with adults and other children,

  • restricted and repetitive patterns of behavior,

  • sensory sensitivities.


Impaired social communication and interaction

Impaired social communication and interaction involve difficulties understanding language, body language, intentionality, empathy, nonverbal cues like facial expressions or eye contact, and social reciprocity.


People with ASD often have difficulty initiating conversations or engaging in meaningful interactions. They may also struggle to make friends or develop relationships outside their family.


Restricted and repetitive patterns

Restricted and repetitive patterns include limited interest in activities as well as rigid adherence to routines or rituals like always eating the same food or playing the same game in a specific order.


Repetitive behaviors such as hand flapping, rocking back and forth, or repeating certain words or phrases can also be signs of Autism.


Sensory sensitivities

Sensory sensitivities. People with ASD may be overly sensitive to noise, light touch, taste odors, or temperature changes. They may become overwhelmed in busy environments like malls due to sensory overload.


Some people may seek out intense sensations, such as spinning around in circles, while others may avoid them altogether.


Early diagnosis and intervention, such as speech therapy sessions and introducing structure (daily routine) into everyday life, can help children on the spectrum cope better with their unique challenges on a daily basis.
