Standardised tools for assessing speech and language delay
Early-childhood speech-language assessment uses norm-referenced standardised tools selected by age and domain — PLS-5, CELF, REEL-4/RDLS and MacArthur-Bates CDI for language; PPVT/EOWPVT for vocabulary; GFTA/DEAP for speech sound; plus ASQ/M-CHAT-R and RBSK screening — interpreted alongside hearing, oral-motor exam and a language sample under clinician judgement.

Before therapy planning comes measurement — and in early childhood speech-language assessment, the right tool turns a parent's concern into a defensible clinical baseline.
In short
Assessment of speech and language delay (ICD-11 6A01) combines norm-referenced standardised tools with structured observation and parent report. There is no single instrument; the clinician selects by age, language profile and presenting domain — receptive language, expressive language, articulation/phonology and pragmatics. In multilingual Indian contexts, tools are used with culturally appropriate adaptation and clinical judgement, never as a stand-alone verdict.
The tools, by domain
Comprehensive language (receptive + expressive)
- PLS-5 (Preschool Language Scales) — birth to ~7 years
- CELF Preschool-2 / CELF-5 — preschool to school age
- REEL-4 / RDLS — receptive–expressive language in infants and toddlers
Vocabulary & early communication
- MacArthur-Bates CDI — parent-report inventory for ~8–30 months
- PPVT / EOWPVT — single-word receptive and expressive vocabulary
Speech sound / articulation & phonology
- GFTA / DEAP — articulation and phonological process analysis
Screening & developmental context
- ASQ / M-CHAT-R for broad developmental and social-communication screening; locally, RBSK screening flags children for referral.
Reliable interpretation requires a hearing check, oral-motor examination and a spontaneous language sample alongside any score.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are established only at a Pinnacle Blooms Network centre, by qualified clinicians — never from an app or a single test score. Our speech therapy teams pair standardised tools with structured clinician assessment; see how the AbilityScore is calculated and how it maps to speech and language delay.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
No single test is sufficient — always cross-check standardised scores against a hearing screen, oral-motor examination and a spontaneous language sample, and adapt for the child's home language(s).
In everyday life
When selecting a battery, anchor first on chronological age and the child's dominant language, then add domain-specific tools only where the screen flags concern.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Is one standardised test enough to confirm a language delay?
No. Standardised scores are interpreted alongside a hearing check, oral-motor examination, structured observation and a spontaneous language sample. Diagnosis is a clinical formulation, not a single score.
How are these tools applied in multilingual Indian settings?
Tools are selected for the child's dominant language and applied with culturally appropriate adaptation and clinical judgement, since most norms are not standardised on Indian multilingual populations. Parent-report measures like the CDI and clinician observation add essential context.
At what age can language be formally assessed?
Structured parent-report and observational tools (e.g. MacArthur-Bates CDI, REEL-4) apply from infancy; comprehensive norm-referenced batteries such as PLS-5 are used from the toddler years onward, with tool choice driven by chronological age.
