# Screening and Diagnostic Pathway for Intellectual Disability in Children Under 7

Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

For children under 7, the pathway is developmental surveillance at every contact, validated screening when concern arises, then multidisciplinary formal assessment combining standardised cognitive and adaptive testing — with hearing/vision and medical causes ruled out first. 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.

*The first clinician to notice a pattern of delay sets the entire trajectory — a structured pathway turns that concern into timely answers.*

## In short
For 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.

## The pathway, step by step
**1. Surveillance (every contact).** Use CDC/IAP milestone checklists at each visit; weight persistent parental concern heavily.

**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.

**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.

**4. Aetiological work-up.** Consider chromosomal microarray, fragile-X and metabolic screening per IAP/AAP guidance where indicated; identify reversible contributors.

**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.

## The Pinnacle way
A 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.

## Trusted sources
WHO 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).

**Next step —** Refer a child with persistent delay for a structured Pinnacle assessment to establish a measurable baseline and plan.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
