Tool choice follows age and presenting concern, with serial re-measurement to track trajectory.","answer_md":"*When a young child's development lags across several domains, the right standardised tools turn a clinical hunch into a measurable, actionable profile.*\n\n## In short\nGlobal Developmental Delay (GDD) — significant delay in two or more domains in children under five — is assessed using a tiered set of standardised tools: validated **screeners** (ASQ-3, M-CHAT-R/F under India's RBSK 4-Ds framework) followed by clinician-administered **diagnostic developmental measures** (Bayley Scales of Infant and Toddler Development, Griffiths III, DDST-II/Trivandrum-DDST in Indian settings, and the VSMS/DASII for indigenous calibration). Domain-specific instruments add depth where needed.\n\n## The instruments, by tier\n**Level 1 — Screening (surveillance):** ASQ-3 and the CDC \"Learn the Signs. Act Early.\" milestone checklists for population surveillance; M-CHAT-R/F where social-communication concern co-exists. RBSK operationalises this as the 4-Ds (Defects at birth, Deficiencies, Diseases, Developmental delay).\n\n**Level 2 — Diagnostic developmental assessment:** Bayley-4 (1–42 months) and Griffiths III remain the reference standards for cognitive, motor, language and social-emotional quantification. In Indian practice the Developmental Assessment Scale for Indian Infants (DASII) and Vineland Adaptive Behaviour Scales (VSMS/VABS) provide culturally validated adaptive-functioning data.\n\n**Domain-specific:** Peabody Developmental Motor Scales, REELS/REEL for language, and CARS-2 when autism is in the differential.\n\nTool choice follows age band, presenting concern, and the need for serial re-measurement to track trajectory rather than a single score.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or checklist. Our clinicians integrate these standardised instruments into one structured, [clinician-administered assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated), grounded in 2.5 billion+ data points and 12 validated studies, to build a [GDD intervention plan](/global-developmental-delay) with measurable re-assessment. Where speech and language drive the delay, this links directly to [targeted therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate).\n\n## Trusted sources\nWHO ICD-11 (developmental delay framing); CDC milestone surveillance; AAP/HealthyChildren guidance on developmental screening; Indian Academy of Pediatrics; RBSK 4-Ds screening protocol.\n\n**Next step —** Refer a child with multi-domain delay for a structured Pinnacle developmental assessment to establish a baseline and serial trajectory.\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-global-developmental-delay-in-early-childhood","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
