Online M-CHAT-R Autism Screening
The Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) is a specialized screening tool used to identify children who may be at risk for autism spectrum disorder (ASD). This questionnaire features 20 yes/no questions for parents regarding their child's social, communication, and play behaviors.
The M-CHAT-R is specifically designed for toddlers. If your child is older, we recommend visiting our CAST screener for a more appropriate assessment.
While autism is typically diagnosed in early childhood, some children may not receive a formal diagnosis until later in their development. The CAST is a valuable screening tool for identifying these cases and ensuring children access the support they need. If your child is under the age of 4, we recommend completing the M-CHAT screening tool instead of the CAST for a more age-appropriate assessment.
Understanding the M-CHAT-R Process
Overview
How long will it take?
What areas does the M-CHAT-R cover?
This screening focuses on early behaviors that may signal developmental differences. We support parents in reviewing key areas such as:
- Social interaction
- Communication and gestures
- Shared attention
- Pretend play
- Sensory responses and repetitive actions
How M-CHAT-R Scoring Works
Our team uses the 20-question M-CHAT-R to assess key developmental areas such as social interaction, communication, and play. The results help identify whether additional clinical evaluation may be recommended.
Understanding M-CHAT-R Scoring
Responses on the M-CHAT-R are scored as 0 or 1 depending on whether the behavior is typical or may suggest a risk. Scores are added together to produce a total between 0 and 20, offering an initial screening result.
For most items:
“Yes” = typical behavior (0 points)
“No” = possible concern (1 point)
For reverse-scored items:
“Yes” = possible concern (1 point)
“No” = typical (0 points)
These questions are reversed because the behaviors listed are less typical when they occur
Score Range
What It Means
Next Steps
0-2
Low likelihood of autism-related traits
→ No action required unless there are other developmental concerns
3-7
Indicators of possible autism traits
→ Schedule a professional autism evaluation
8-20
Strong indicators of autism traits
→ Seek a clinical assessment as soon as possible
Next steps after M-CHAT-R ?
Once the M-CHAT-R is completed, our Clinic Admissions team reviews the responses. A team member will typically reach out within one business day to review results and guide you on next steps.
What to expect based on your child’s score:
Low score(0–2)
- Most children in this range are unlikely to show signs of autism
- You’ll receive confirmation of this result within one business day
- No further steps are typically needed, though you may continue monitoring or consult your pediatrician if concerns arise
Medium score (3–7)
- Indicates a need for closer observation
- This does not confirm autism, but discussing concerns with your pediatrician is recommended
- A more detailed evaluation may be suggested
High score(8–20)
- Suggests a higher likelihood but is not a diagnosis
- You’ll be contacted within one business day to review next steps
- May include scheduling an ADOS-2 diagnostic assessment, a widely used in-person evaluation tool

Kindly answer the following questions based on your child’s typical behavior. If your child has only demonstrated a behavior occasionally and not on a regular basis, please select “No.” Be sure to respond to every question with either “Yes” or “No.”
M-CHAT-R frequently asked questions
What is the purpose of the M-CHAT-R?
Why does early autism detection matter?
Detecting Autism Spectrum Disorder early helps children receive timely intervention such as EIBI. ABA therapy has been shown to improve communication, social skills, and school readiness while reducing challenging behaviors. Parents and caregivers are important in observing and supporting their child’s development.
What is therapy?
ABA therapy focuses on helping children with autism build essential life skills through guided learning and behavioral support.
