Global Developmental Delay
Screening and diagnostic pathway for Global Developmental Delay under 7
For children under 7, the pathway is developmental surveillance at every visit, validated screening at defined ages, and prompt multidisciplinary diagnostic evaluation when two or more domains fall significantly below age level. GDD is a finding under age 5 that mandates aetiological workup, not an endpoint — and intervention should begin in parallel, never waiting for a cause to be identified.
Most children with developmental concern arrive in primary care first — the pathway you set in motion decides how fast they reach intervention.
In short
For a child under 7, the recommended pathway is structured developmental surveillance at every contact, formal validated screening at defined ages, and timely referral for multidisciplinary diagnostic evaluation when two or more developmental domains fall significantly below age expectation. Global Developmental Delay (GDD) is a clinical descriptor for children under 5 in whom standardised cognitive testing is not yet reliable; above that age, formal assessment usually reclassifies toward a specific diagnosis. Crucially, GDD is a finding that mandates aetiological workup — not an endpoint.The pathway, step by step
1. Surveillance — Monitor against milestone domains (gross/fine motor, speech-language, cognition, social-emotional, adaptive) at every well-child visit, integrating parental concern as a high-sensitivity signal.2. Screening — Apply a validated tool (ASQ-3, or the RBSK 4-Ds framework in the Indian context) at scheduled points; positive screen or two-domain delay triggers referral.
3. Diagnostic evaluation — Multidisciplinary assessment with standardised developmental/cognitive measures, plus a tiered medical workup: hearing and vision, then targeted investigations — chromosomal microarray, fragile-X, metabolic and neuroimaging studies as indicated — to identify an aetiology in the substantial proportion where one is found.
4. Intervention in parallel — Do not delay therapy pending aetiology. Early intervention begins on identified need.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a screen alone. Our Global Developmental Delay pathway pairs structured assessment with co-ordinated early intervention therapy, and the clinician-administered AbilityScore® provides a calibrated baseline for measuring progress.Trusted sources

What to watch
Two or more developmental domains significantly below age expectation, any loss of acquired skills, or persistent parental concern — each warrants referral for multidisciplinary evaluation rather than continued watchful waiting.
Try this at home
Treat parental concern as a positive screen in its own right — it has high sensitivity and should lower, not raise, your threshold to refer.

Frequently asked
At what age is the term Global Developmental Delay appropriate?
GDD is applied to children under 5 with significant delay in two or more developmental domains, where standardised cognitive testing is not yet reliable. Above this age, formal assessment usually allows reclassification toward a specific diagnosis such as intellectual disability or a defined neurodevelopmental condition.
Should therapy wait until an aetiology is identified?
No. Early intervention should begin on identified developmental need, in parallel with the medical workup. Delaying therapy while awaiting investigation results costs valuable developmental time.
What medical investigations are considered in GDD?
After hearing and vision assessment, a tiered workup may include chromosomal microarray, fragile-X testing, targeted metabolic studies and neuroimaging, guided by history and examination findings to identify an underlying cause where present.
