# When to escalate a child's delay in understanding

A frontline health worker should escalate when a child understands clearly less than peers and the gap persists — for example no response to name or simple words by 18 months, or not following one-step instructions by 2 years in the home language. Any loss of understanding once present needs prompt referral, and hearing should always be checked first. This is a reason to assess early, never a diagnosis.

*A frontline worker who pauses to notice how a child understands everyday words is already doing the most valuable early work there is.*

## In short
Escalate to a developmental check when a child clearly understands less than other children of the same age **and** the gap is persistent, not just shy-day behaviour — for example, by around 18 months not turning to their name or following simple words like *come* or *give*, or by 2 years not following easy one-step instructions in their home language. One firm rule: **any loss of understanding a child once had needs prompt referral.** This is a reason to assess early, never a diagnosis.

## What to watch (ICF d1, understanding)
Understanding — receiving and making sense of spoken words, gestures and routines — usually comes *before* talking. Refer for a developmental check when you see:

- **By 9–12 months** — no response to their name, no looking when you point or wave *bye-bye*.
- **By 18 months** — not following simple familiar words (*give*, *come*, *no*) or pointing to a named object or body part.
- **By 24 months** — not following a simple one-step instruction without gestures, in the family's everyday language.
- **At any age** — losing words or comprehension once present, no response to sound, or a parent who feels their child "doesn't seem to hear or understand".

Always check hearing first — undetected hearing loss is the commonest, most treatable reason a child seems not to understand. Ask in the home language, not only in a clinic tongue.

## When to escalate
Don't wait-and-watch a clear, persistent gap. Refer to a paediatrician or developmental service when a milestone window has passed, when there is any regression, or when a parent is worried — parental concern alone is a valid trigger.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a checklist in the field. Our team assesses how a child [understands](/understanding) language and routines, and our [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) clinicians build comprehension through play.

## Trusted sources
WHO ICF framework (domain d1, learning and applying knowledge); CDC "Learn the Signs, Act Early" developmental milestones; AAP / healthychildren.org developmental surveillance guidance.

**Next step —** Trust the concern you've noted. [Book a developmental assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) so a clinician can review the child's hearing, understanding and milestones early.

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