Non-Verbal / Minimally Verbal Presentation
ICF Functioning Domains Affected by a Non-Verbal / Minimally Verbal Presentation
In the WHO ICF framework, a non-verbal / minimally verbal presentation in early childhood chiefly affects Activities and Participation — Communication (d310–d369) and Interpersonal interactions (d710–d799) — and Body Functions of language (b167) and speech (b310–b399), extending into learning and play, all modified by environmental factors.
A non-verbal or minimally verbal presentation is rarely about speech alone — it ripples across how a young child connects, learns and manages the everyday.
In short
Using the WHO's ICF framework, a non-verbal / minimally verbal presentation in early childhood most directly affects the Activities and Participation domains — particularly Communication (d310–d369) and Interpersonal interactions and relationships (d710–d799) — and the Body Functions of Mental functions of language (b167) and Voice and speech functions (b310–b399). It commonly extends into Learning and applying knowledge (d110–d179) and Major life areas such as early play and pre-school participation. ICF frames these as functioning domains shaped by environmental and personal contextual factors — not as a fixed deficit — which is precisely why support and communication access change outcomes.Mapping the domains
Body Functions (b)- b167 Mental functions of language — reception and expression of spoken/signed language.
- b310–b399 Voice and speech functions — articulation, fluency and voice production where relevant.
Activities & Participation (d)
- d310–d329 Communicating — receiving (spoken, non-verbal, signed messages).
- d330–d349 Communicating — producing (speaking, producing non-verbal messages, alternative methods).
- d350–d369 Conversation and use of communication devices/techniques — directly relevant where AAC is introduced.
- d710–d799 Interpersonal interactions and relationships — initiating, sustaining and regulating social exchange.
- d110–d179 Learning and applying knowledge — where language scaffolds early cognition.
- d880 Engagement in play and emerging Major life areas (pre-school participation).
Contextual factors — Environmental factors (e) such as access to AAC, responsive communication partners and inclusive early-years settings materially modify participation; these are coded, not incidental.
A note for the clinician
ICF deliberately separates capacity (what the child can do in a standardised environment) from performance (what they do in their real-world setting). For a minimally verbal child this gap is often where intervention leverage sits — provide a communication method and performance rises even before capacity shifts. Document both, and code the environmental facilitators you put in place.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 tool or article. Our clinicians map a child's profile against ICF functioning domains to build a communication-first therapy plan, and explain how this translates into a single, trackable baseline via the AbilityScore.

What to watch
Watch the gap between capacity (standardised setting) and performance (everyday setting): when a communication method is introduced and real-world participation rises faster than tested language ability, the environment was the limiting factor — code and build on it.
Try this at home
When documenting, always pair a Body Function code (e.g. b167) with the matching Activities & Participation code (e.g. d330) and the environmental facilitator you introduced — it shows where intervention is working.

Frequently asked
Is a non-verbal presentation an ICF diagnosis?
No. ICF does not diagnose — it describes functioning. A non-verbal or minimally verbal presentation is captured as a functioning profile across Body Functions and Activities & Participation domains, with environmental factors that modify it. Diagnosis sits within ICD-11 and is established clinically.
Which single ICF domain is most central?
Communication within Activities & Participation — receiving messages (d310–d329), producing messages (d330–d349) and conversation including communication devices (d350–d369) — paired with the Body Function of mental functions of language (b167).
How does AAC fit into ICF coding?
Augmentative and alternative communication is captured both as an Activity (d360 using communication devices and techniques) and as an Environmental facilitator (e-codes for assistive products and supportive partners), reflecting that the method itself raises participation.
