YOUR QUESTION. A CLEARER NEXT STEP.
Assessing and Tracking Non-Verbal Communication in Children
A clinician assesses non-verbal communication (ICF d3) through structured, play-based observation of gaze, gestures, joint attention and intentional acts, sampled across contexts and triangulated with caregiver report. Progress is tracked via operationalised goals and repeated video-coded probes — never a single number — with audiology and motor causes ruled out first.

When words have not yet arrived, a child's gestures, gaze and shared joy tell the whole story — and they can be measured with care.
In short
Non-verbal communication (ICF d3) is assessed through structured, criterion-referenced observation of how a child uses gaze, gestures, facial affect, joint attention and intentional acts to share and request — sampled in naturalistic play and caregiver interaction, then re-sampled at fixed intervals to chart trajectory. There is no single number; you build a profile across functions and contexts, triangulated with caregiver report, and set operationalised goals you can track session over session.
The science of measuring it
Map performance against the developmental hierarchy of intentional communication, not just frequency:
- Communicative functions — behaviour regulation (requesting, protesting) versus joint attention and social interaction; weight emergence of declarative pointing and showing.
- Form complexity — from contact gestures to distal pointing, gaze alternation, and conventional/symbolic gestures.
- Rate and spontaneity — acts per minute, prompted versus spontaneous, and repair attempts when not understood.
- Cross-context generalisation — clinic, home, with familiar and unfamiliar partners.
Use standardised, play-based tools (e.g. CSBS-style communication temptations, ADOS-2 social-communication press for relevant referrals) alongside parent-report inventories (MacArthur-Bates CDI gestures). Operationalise each goal — "initiates joint attention via gaze-plus-point ≥5 times in a 10-minute sample" — and use repeated video-coded probes for a reliable progress curve. Rule out hearing, motor and apraxic constraints before attributing plateaus to communication intent.
When to escalate
Flag absent gaze alternation, no gestural repertoire by ~12 months, or regression for prompt audiology and developmental review rather than therapy-only watchful waiting.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — our AbilityScore® is a clinician-administered structured assessment that benchmarks the child against their own baseline. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, clinicians pair this with speech therapy and targeted work on non-verbal communication. See what the AbilityScore is and how it's calculated.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for absent gaze alternation, no gestural repertoire by around 12 months, reliance on prompted rather than spontaneous acts, or loss of previously emerged gestures — and confirm hearing and motor status before attributing plateaus to communication intent.
In everyday life
Code short video samples of naturalistic play at fixed intervals: count spontaneous communicative acts, note their function (request versus share), and review with the caregiver to align home and clinic data.
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
Which functions of non-verbal communication should be assessed first?
Distinguish behaviour-regulation acts (requesting, protesting) from joint-attention and social-interaction acts. Emergence of declarative pointing, showing and gaze alternation is developmentally weighted, so profile functions separately rather than counting total acts.
How should progress be tracked reliably over time?
Use operationalised, measurable goals and repeated video-coded probes in matched contexts at fixed intervals. Track rate, spontaneity, form complexity and cross-context generalisation rather than a single score.
What should be ruled out before attributing a plateau to communication intent?
Confirm hearing status via audiology and screen for motor or apraxic constraints, since these can suppress gestural and gaze behaviours independently of communicative intent.
