Assessing and Tracking Non-Verbal Communication Progress
A clinician assesses non-verbal communication by baselining functional communication acts — joint attention, gesture, communicative intent, responsiveness and modality flexibility — within ICF domain d3, then re-measuring against the child's own baseline using coded play probes, criterion-referenced inventories and Goal Attainment Scaling at 8–12-week intervals, sampling across partners to confirm generalisation.
Non-verbal communication is the foundation skill — gestures, eye gaze, joint attention and intent — and it can be measured with the same rigour as spoken language.
In short
A clinician tracks non-verbal communication by establishing a structured baseline of functional communication acts — eye contact, joint attention, gesture, pointing, requesting and turn-taking — then re-measuring against that child's own baseline at defined intervals. Progress is captured through coded observation, validated checklists and goal-attainment scaling, not a single score. This sits within ICF domain d3 (Communication), framing the skill functionally rather than by deficit.The science: what to measure and how
For a pre-verbal or minimally verbal child, prioritise the building blocks that predict expressive language:- Joint attention — initiating and responding to shared focus (gaze shifting, showing, pointing to comment).
- Communicative intent — frequency and range of functions: requesting, protesting, commenting, social greeting.
- Gesture inventory — reach, give, point, conventional gestures, sign or AAC symbol use.
- Responsiveness — response to name, simple instructions, turn-taking in interaction.
- Modality flexibility — whether the child generalises across people, settings and AAC/PECS where introduced.
Track with: rate-per-minute coding of communicative acts in standardised play probes, criterion-referenced inventories (e.g. communication matrices and developmental profiles), and Goal Attainment Scaling for individualised, sensitive change detection. Re-measure every 8–12 weeks, video-sample for inter-rater reliability, and chart trends rather than isolated sessions. Always sample across communication partners to confirm generalisation.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from an online figure or checklist. The AbilityScore® is a clinician-administered structured assessment that benchmarks a child against their own baseline, turning serial observation into an actionable plan. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our teams pair this with speech therapy and AAC pathways. Explore non verbal communication and what the AbilityScore is and how it's calculated.Trusted sources

What to watch
Watch for plateaus in communicative-act rate, narrow range of functions (only requesting, no commenting), poor generalisation across partners or settings, and limited joint-attention initiation — these signal the need to adjust goals or modality.
Try this at home
Sample communication across at least two partners and settings before drawing conclusions — a child who points only with one therapist has not yet generalised the skill.

Frequently asked
Which non-verbal behaviours should I prioritise measuring first?
Begin with joint attention, communicative intent (range of functions), gesture inventory and responsiveness. These pre-verbal building blocks most strongly predict later expressive language and give the most sensitive early markers of change.
How often should non-verbal progress be re-measured?
Re-measure every 8–12 weeks using consistent standardised play probes and criterion-referenced inventories, charting trends rather than reacting to single-session variation. Video-sampling supports inter-rater reliability.
Can Goal Attainment Scaling detect small gains?
Yes. Goal Attainment Scaling is individualised and sensitive to incremental change, making it well suited to minimally verbal children where standardised norm-referenced tests may show floor effects.
