It is a participation profile across two or more domains, not a single deficit.","answer_md":"*A clinician's first task with Global Developmental Delay is not the label — it is mapping where, across functioning, the child needs support.*\n\n## In short\nGlobal Developmental Delay (GDD) is, by definition, significant delay in **two or more** developmental domains in a child under five who is too young for reliable standardised IQ testing. Mapped onto the WHO ICF framework, it most consistently affects **Learning and applying knowledge (cognition)**, **Communication**, **Mobility (gross and fine motor)**, **Self-care**, and **Interpersonal interactions and relationships** — with **Major life areas (play)** and contextual **Environmental factors** shaping the functional picture. GDD is best read as a profile across these activity-and-participation domains, not a single deficit.\n\n## The ICF domains in early childhood\nUnder the ICF *Activities and Participation* component, GDD typically presents across:\n\n- **d1 Learning and applying knowledge** — early cognition, imitation, problem-solving, symbolic play and pre-academic skills.\n- **d3 Communication** — receptive and expressive language, gesture, and early social-communication exchange.\n- **d4 Mobility** — gross-motor milestones (sitting, walking) and fine-motor manipulation (grasp, transfer).\n- **d5 Self-care** — feeding, dressing, toileting and emerging independence.\n- **d7 Interpersonal interactions and relationships** — joint attention, turn-taking and relating to caregivers and peers.\n- **d8/d9 Major life areas & community life** — participation in play and early-learning settings.\n\nThese sit alongside *Body functions* (b1 mental functions, b7 neuromusculoskeletal/movement) and are modulated by **Environmental factors** (e3 support, e5 services) and **Personal factors**. The ICF lens reframes GDD from a static category into a participation-focused profile — exactly what drives goal-setting in early intervention.\n\n## When to refer\nGDD in a child under five warrants structured developmental assessment and routing into early intervention; persistent delay across domains, regression, or red flags on routine screening (e.g. RBSK 4 Ds) should prompt prompt paediatric and developmental-therapy referral. The label is provisional — it is re-evaluated as the child matures toward an age where cognitive testing becomes valid.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online tool.
