High test scores on the M-CHAT-R test results indicate 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.

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

  • Medium Risk: Total Score 3-7 indicates a medium risk of Autism and suggests that more in-depth review is needed.

  • High Risk: Total Score 8-20 indicates a high risk of Autism and requires formal Autism assessment with your child's healthcare provider, developmental pediatrician or child psychologist to receive an accurate diagnosis.
