M-CHAT-R/F Autism Screening
A 20-item parent questionnaire that screens for autism risk in children aged 16-30 months.
In one minute
How it works in 3 steps
- The parent completes it: Simple items about the child's development are marked.
- A risk level emerges: A low, moderate, or high risk range is determined.
- It directs to a professional: At moderate and high risk, a detailed assessment is recommended.
Who it informs
When professional support helps
What does the M-CHAT-R/F measure?
The questionnaire assesses simple observations of the child's social communication, joint attention, and interaction behaviours. It makes visible whether there is an early sign of risk.
A moderate or high risk result does not confirm that there is a problem; it only points to a comprehensive developmental assessment being useful. Early assessment is valuable in terms of early support — a positive screen means it is worth a professional assessment, not a label.
How is it scored?
The items are marked and summed; the total score falls into low, moderate, and high risk ranges. At moderate risk, the assessment is deepened with follow-up questions.

What do the score bands mean?
The ranges below are a general frame. No band makes a diagnosis on its own; a result only becomes meaningful when a clinical psychologist interprets it alongside your life story.
| Score | General interpretation |
|---|---|
| 0–2 | Low risk |
| 3–7 | Moderate risk – monitoring advised |
| 8–20 | High risk – further assessment needed |
Limitation: It is a screening questionnaire; it does not diagnose autism and never makes a diagnosis on its own. A definitive assessment requires a comprehensive developmental evaluation by a professional team.
Psychometrics and source
With the revised form and the follow-up interview, the positive predictive value has risen markedly compared with the original form; a substantial proportion of screen-positive children are reported to show autism spectrum disorder or another developmental delay.
