Screening a child's communication development

A frontline worker — ASHA or PHC nurse — is often the first to notice when a child's babble, words or understanding aren't keeping pace, and that early eye can change a life.

In short

A frontline worker screens communication by watching and asking about age-expected listening, understanding and talking milestones — does the baby respond to sound and turn to voices, does the toddler babble, point and follow simple instructions, does the older child join words into phrases. You don't diagnose; you compare against a short milestone checklist, ask the parent two or three direct questions, and refer onward if anything is delayed or if the family is worried. A simple, structured look at receptive (understanding) and expressive (talking) skills is enough to decide who needs a closer assessment.

A practical screening approach

Use a quick listen–understand–talk frame at every contact:

• Hearing and attention — Does the child startle or quieten to sound? Does a baby turn toward a voice? By 6–9 months, does babbling have varied sounds (ba-ba, da-da)? No response to sound at any age is a red flag for prompt hearing and developmental review.
• Understanding (receptive) — By ~12 months, does the child respond to their name and simple words like "bye"? By 18–24 months, can they point to a named body part or fetch a familiar object on request?
• Talking (expressive) — First words by ~12–15 months; several single words by 18 months; two-word phrases ("more milk") by ~24 months; short sentences others can mostly understand by 3 years.
• Social communication — Does the child make eye contact, point to show interest, and share attention? Reduced pointing, gestures or response to name warrants a wider developmental check, not communication alone.
• Ask the parent directly — "Are you worried about how your child hears, understands or talks?" Parent concern is one of the strongest signals and should always be taken seriously.

Note what you see against the local milestone or DSTK-style checklist, count any clear delays, and record whether the parent has concerns. Two simple flags — a missed milestone for the age band or a worried parent — are enough to refer.

When to refer

Refer for a formal developmental and hearing assessment if: the child shows no response to sound at any age; no babble by 9 months; no single words by 16–18 months; no two-word phrases by 24 months; any loss of words or skills already gained; or the parent is concerned. Loss of previously acquired language is always urgent. Frame referral as a positive next step, never as bad news — early support is when help works best.
