Both axes — intellectual and adaptive functioning — must show deficits, and below ~5 years results read as developmental functioning, not fixed IQ.","answer_md":"*The right tool at the right age turns a clinical hunch into a defensible developmental profile.*\n\n## In short\nIn early childhood, intellectual disability (ICD-11 6A00) is assessed using a **paired battery**: a standardised cognitive/developmental measure plus an independent adaptive-behaviour measure — because 6A00 requires deficits in **both** intellectual functioning and adaptive functioning, confirmed before a diagnosis stands. No single instrument is sufficient, and below roughly 5 years results are interpreted as developmental functioning, not a fixed IQ.\n\n## The instruments clinicians use\n**Cognitive / developmental functioning**\n- **Bayley Scales of Infant and Toddler Development (Bayley-4)** — cognitive, language and motor domains, ~1–42 months.\n- **Wechsler Preschool & Primary Scale of Intelligence (WPPSI-IV)** — from ~2 years 6 months.\n- **Mullen Scales of Early Learning** and **Griffiths Scales** — early developmental profiling.\n- **Stanford–Binet (SB-5)** — extends into the lower preschool range.\n\n**Adaptive behaviour (essential second axis)**\n- **Vineland Adaptive Behavior Scales (Vineland-3)** — communication, daily living, socialisation, motor.\n- **Adaptive Behavior Assessment System (ABAS-3)** — caregiver/teacher report from birth.\n\nIn the Indian context, locally validated tools such as the **Developmental Profile** and **DASII (Developmental Assessment Scale for Indian Infants)** support culturally appropriate norming. Always pair with hearing and vision screening to exclude sensory confounds.\n\n## When this is meaningful\nFormal cognitive scores stabilise after ~5 years; before that, document **global developmental delay** and re-assess. Interpret scores alongside developmental history and direct observation — never in isolation.\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 a single test sheet. Our clinician-administered structured assessment integrates these standardised measures into one calibrated developmental picture. Explore [Intellectual Disability](/intellectual-disability), our [developmental assessment pathway](/developmental-assessment), and [how the AbilityScore® is calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nWHO ICD-11 6A00 (Disorders of intellectual development); CDC developmental milestones; Indian Academy of Pediatrics; AAP HealthyChildren guidance.\n\n**Next step —** Refer or co-assess with a Pinnacle clinical team to formalise a developmental profile [here](/developmental-assessment).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/which-standardised-tools-are-used-to-assess-intellectual-disability-in-early-childhood","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
