It is a description of support needs, not a verdict — and Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional.","answer_md":"*Every parent wants to understand the word before they fear it — so let's start with what Intellectual Disability actually means.*\n\n## In short\nIntellectual Disability (ICD-11 **6A00**, *Disorders of intellectual development*) describes meaningful differences in two areas that begin during childhood: **intellectual functioning** — reasoning, learning, problem-solving — and **adaptive behaviour**, the everyday skills like communication, self-care and getting along with others. It is not an illness and not a verdict on a child's future; it is a description of where a child needs more support to learn and grow. Many children with the right early support make remarkable, lifelong gains in independence.\n\n## The science, briefly\nClinicians look at how a child thinks and learns *and* how they manage daily life, across home, school and play — never from a single test or a single moment. Because young children develop at very different rates, a careful professional assessment matters more than any label, and support is tailored to the child in front of us. Early, structured help — in communication, learning and self-care — is what changes the trajectory most.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an app or online form. From there your family gets a clear baseline and a plan you can follow through [special education](/special-education) and daily routines.
