Non-Verbal
Measuring and tracking non-verbal communication in therapy
Non-verbal communication is measured by baselining intentional communicative acts — gaze, gesture, joint attention, vocalisation and AAC use — then tracking frequency, modality and independence against the child's own starting point across repeat structured observation. Progress is read as expanding communicative function, not spoken words alone, and an AbilityScore® and any diagnosis are formed only at a Pinnacle centre under clinician care.
A non-verbal child is communicating in every moment — our task is to measure those signals reliably and watch them grow.
In short
Non-verbal communication is measured by establishing a structured baseline of intentional communicative behaviours — eye gaze, gesture, joint attention, vocalisation, symbol or AAC use — then tracking change against that child's own starting point across sessions. There is no single number; a clinician operationalises target behaviours, quantifies frequency and modality, and reviews trajectory through repeat structured observation. Progress is read as expanding communicative function, not merely spoken words.How it is measured and tracked
For a pre-verbal or minimally-verbal toddler, the clinician anchors measurement in observable, intentional acts:- Communicative functions — requesting, protesting, commenting, sharing — coded by frequency and spontaneity versus prompted.
- Modality profile — gaze, point, reach, sign, picture exchange, vocal approximation, or device-based AAC — tracked so emerging channels are credited.
- Joint attention and turn-taking — initiating versus responding, and the duration of shared engagement.
- Rate and independence — communicative acts per activity, and the prompt-level fading over time.
- Generalisation — whether targets carry across people, settings and routines.
Data are gathered through repeat structured observation, caregiver report and session sampling, then plotted against the baseline so the plan is adjusted on evidence rather than impression. Comprehension, oral-motor and sensory factors are reviewed in parallel to keep targets functional.
When to escalate
Flag for clinician review if communicative initiations plateau across review cycles, if a modality is regressing, or if comprehension–expression gap widens — these reshape goal-setting and may indicate AAC introduction or interdisciplinary input.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care; the AbilityScore® is a clinician-administered structured assessment read against the child's own baseline, drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres. Pair measurement with speech therapy and family coaching. See Non-Verbal and what the AbilityScore is and how it's calculated.Trusted sources

What to watch
Escalate for clinician review if communicative initiations plateau across review cycles, a working modality regresses, prompt-dependence fails to fade, or the comprehension–expression gap widens.
Try this at home
Count and credit every intentional signal — a glance, a reach, a point — in daily routines, and respond consistently so the child learns that communication works.

Frequently asked
Is there a single score for non-verbal ability?
No. Measurement is a profile of intentional communicative behaviours — function, modality, frequency and independence — read against the child's own baseline rather than reduced to one figure.
Does introducing AAC reduce spoken language?
Evidence does not support that concern; AAC and aided communication generally support, not suppress, emerging speech. A clinician decides timing based on the child's communicative profile.
How often is progress reviewed?
Progress is tracked through repeat structured observation and session sampling across review cycles, with goals adjusted on the data rather than on a single sitting.
