YOUR QUESTION. A CLEARER NEXT STEP.
Should my child have an M-CHAT-R/F assessment?
The M-CHAT-R/F is a short, free, parent-completed screening questionnaire for toddlers aged about 16–30 months. It involves 20 yes/no questions plus a brief follow-up interview to clarify flagged answers. It is a screen, not a diagnosis — it indicates whether a fuller developmental assessment may help. It is a sensible step around the 18- and 24-month checks or whenever you have a specific concern.

Wondering if a simple questionnaire could put your mind at ease — or point you towards helpful next steps? Let's walk through it together.
In short
The M-CHAT-R/F is a short, free, parent-completed screening questionnaire for toddlers aged roughly 16 to 30 months. It is not a diagnosis — it simply flags whether a closer developmental look might be worthwhile. If your child is in that age band, or you have noticed differences in communication, eye contact, gestures or play, it is a gentle, sensible step to take.
What the M-CHAT-R/F involves
It comes in two simple stages:
- The 20-question checklist (the "R" — Revised). You answer yes/no questions about everyday behaviours — does your child point to show you things, respond to their name, enjoy peek-a-boo, look where you point, copy you, or use pretend play? It takes only a few minutes.
- The Follow-Up (the "F"). If the first stage flags a few items, a brief structured follow-up interview clarifies those specific answers with examples — because a single "no" on a busy day doesn't tell the whole story. This step reduces false alarms and sharpens the picture.
The result places a child in a low, medium or higher likelihood band for needing a fuller developmental assessment. Think of it as a torch, not a verdict — it shows where to look more closely.
Should your child have one?
A screen is appropriate if your toddler is between about 16 and 30 months, especially around the routine 18- and 24-month checks, or any time you have a specific concern. A screen that suggests further evaluation is not a diagnosis of autism — many children flagged by screening turn out to be developing typically, and others benefit from early support regardless of any label. The value is timing: the earlier a need is spotted, the earlier support can begin.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from a screening questionnaire alone. We use validated screens like the M-CHAT-R/F as a starting point, then our clinicians build the full picture through a structured, clinician-administered AbilityScore assessment and, where helpful, tailored speech and communication therapy. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, we turn early questions into a clear, practical plan you can act on.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Around 16–30 months, watch for whether your child points to show you things, responds to their name, makes eye contact, copies you, enjoys games like peek-a-boo, and uses simple pretend play. A few gaps don't mean a diagnosis — but they're worth a gentle conversation and, if needed, a screen.
In everyday life
Build pointing and shared attention into play: point at something interesting and say "Look!", then wait for your child to follow your gaze or point back. Name what you both see — these tiny shared moments are exactly what early screens look for.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is the M-CHAT-R/F a diagnosis of autism?
No. It is a screening questionnaire that flags whether a fuller developmental assessment may be worthwhile. Many children flagged by screening are developing typically; a diagnosis can only be made by a qualified clinician through a full evaluation.
What age is the M-CHAT-R/F for?
It is designed for toddlers roughly between 16 and 30 months, and is often used around the routine 18- and 24-month developmental checks.
What happens if my child's screen suggests further evaluation?
It simply means a closer developmental look is recommended — not that your child has autism. A Pinnacle clinician will conduct a structured AbilityScore assessment to build the full picture and guide any support.
How long does the M-CHAT-R/F take?
The 20-question checklist takes only a few minutes. If some items are flagged, a brief structured follow-up interview clarifies those specific answers with everyday examples.
