Below age 5 the working label is global developmental delay; a confirmed ICD-11 6A00 diagnosis follows reliable testing. Diagnosis is formed only at a Pinnacle centre under clinician care.","answer_md":"*The first clinician to notice a pattern of delay sets the entire trajectory — a structured pathway turns that concern into timely answers.*\n\n## In short\nFor a child under 7, intellectual disability (ICD-11 **6A00**, *disorders of intellectual development*) is never diagnosed from a single visit. The pathway is **surveillance at every well-child contact → validated screening when concern arises → formal multidisciplinary assessment**. Crucially, before age ~5–6 the working construct is often **global developmental delay**, with a confirmed ID diagnosis reserved for when standardised cognitive and adaptive testing becomes reliable. Always screen vision, hearing and treatable medical causes first.\n\n## The pathway, step by step\n**1. Surveillance (every contact).** Use CDC/IAP milestone checklists at each visit; weight persistent parental concern heavily.\n\n**2. Screening (concern triggered).** Apply a validated tool (e.g. ASQ-3, developmental-milestone surveillance) and rule out sensory deficits — confirm hearing and vision before attributing delay to cognition.\n\n**3. Formal assessment.** Refer for multidisciplinary evaluation combining **standardised cognitive testing** (age-appropriate developmental/IQ measure) and **standardised adaptive-behaviour assessment** — ID under ICD-11 requires deficits across *both* intellectual and adaptive domains.\n\n**4. Aetiological work-up.** Consider chromosomal microarray, fragile-X and metabolic screening per IAP/AAP guidance where indicated; identify reversible contributors.\n\n**5. Re-assessment.** Below age 5, label as global developmental delay and re-evaluate as test reliability improves — diagnosis is dynamic, not a one-off verdict.\n\n## The Pinnacle way\nA clinical **AbilityScore®** and any diagnosis are established only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app or online form. Our [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) is a clinician-administered structured assessment that maps functioning across communication, cognition, motor, social and self-care, giving you a measurable baseline. Explore the [intellectual disability pathway](/intellectual-disability) and our [early intervention programme](/early-intervention-therapy) to convert assessment into a plan.\n\n## Trusted sources\nWHO ICD-11 6A00 (disorders of intellectual development); CDC *Learn the Signs. Act Early.* milestone surveillance; Indian Academy of Pediatrics developmental evaluation guidance; American Academy of Pediatrics (HealthyChildren.org).\n\n**Next step —** Refer a child with persistent delay for a structured Pinnacle assessment to establish a measurable baseline and plan.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-is-the-recommended-screening-and-diagnostic-pathway-for-intellectual-disability-in-children-under-7","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
