In young children, clinicians are often cautious, using 'global developmental delay' first. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional.","answer_md":"*When a parent senses their child is learning the world at a different pace, the first kind step is understanding — and a diagnosis is simply careful understanding, done well.*\n\n## In short\nIntellectual Disability is diagnosed by a qualified clinician who looks at two things together: how a child **thinks, reasons and learns** (cognitive development), and how they **manage everyday life** — communicating, playing, self-care and getting along with others (adaptive functioning). Both are assessed against what is typical for the child's age, using structured, clinician-administered tools — never a single test or an online quiz. Crucially, this is a careful, multi-step process, and an early concern is a reason to *check*, not to fear.\n\n## How the diagnosis is made\nA thorough assessment usually brings together several strands:\n- **Developmental and family history** — pregnancy, birth, milestones, medical history and how your child is doing at home and in any childcare or school setting.\n- **A structured cognitive assessment** — age-appropriate tasks that look at reasoning, memory, learning and problem-solving.\n- **An adaptive-functioning profile** — how your child copes with daily routines, communication, social interaction and self-care, gathered partly from you, because parents see what no clinic room can.\n- **Hearing, vision and medical review** — to make sure a sensory or treatable issue isn't being mistaken for a learning difference.\n\nUnder WHO ICD-11 (6A00, Disorders of Intellectual Development), a diagnosis rests on **both** significant cognitive *and* adaptive differences, observed during the developmental period. In very young children, clinicians are often deliberately cautious — labels like \"global developmental delay\" may be used first, with a clearer picture confirmed as the child grows. That patience protects your child.\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 app, a form, or this page.
