Selective Mutism (ICD-11 6B06) presents as consistent failure to speak in specific settings — usually school — despite fluent speech at home. Refer when situational silence persists beyond a month of a new setting, interferes with function, and isn't explained by a language disorder, hearing loss, or unfamiliarity with the language of instruction.

*A child who chats freely at home but falls silent at school isn't being defiant or shy — they may be showing the consistent, situation-bound silence that defines Selective Mutism.*

## In short
Selective Mutism (ICD-11 6B06) presents as a consistent failure to speak in specific social situations where speech is expected — most often school — despite fluent, age-appropriate speech in comfortable settings such as home. Watch for a pattern that persists beyond the first month of a new setting, is not better explained by a communication disorder or lack of language familiarity, and meaningfully interferes with academic or social functioning. Early recognition matters because the longer the silence is reinforced, the more entrenched it becomes.

## Early indicators worth watching for
**Situational, consistent silence**
- Speaks freely and fluently at home, yet does not speak at school, in clinic, or with unfamiliar adults
- The pattern is consistent and predictable by setting — not occasional or mood-dependent
- Silence persists beyond the typical settling-in month of a new environment (creche, nursery, school)

**Associated behavioural signs**
- Marked anxiety, freezing, or a "blank" expressionless face when speech is expected
- Uses gestures, nodding, pointing, or written notes rather than speaking
- Avoidance of eye contact and reluctance to initiate; may cling or withdraw in group settings
- Co-occurring features of social anxiety, behavioural inhibition or a shy/inhibited temperament

**Differentiators to note in history**
- Speech and language are intact in comfortable settings — rule out underlying speech-sound or language disorder
- Consider whether reduced speech reflects unfamiliarity with the language of instruction (common in multilingual Indian settings) rather than Selective Mutism
- Exclude hearing concerns and review for any global developmental delay

## When to refer
Refer when situational mutism has persisted for more than one month (excluding the first month of school) and interferes with learning or peer relationships. "They'll grow out of it" is not a safe default — untreated Selective Mutism tends to consolidate. Arrange a parallel hearing check and a [speech and language assessment](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate), and route to a multidisciplinary team for confirmation and graded behavioural intervention. A formal diagnosis is a clinical decision, not the result of a single observation.

## The Pinnacle way
Pinnacle Blooms Network supports your referral pathway with structured developmental profiling: the clinician-administered [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) provides an objective, multi-domain baseline that complements your impression and tracks change once intervention begins. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from a screen or score alone. Learn more about [Selective Mutism](/selective-mutism) and the supporting therapy pathway.

## Trusted sources
Aligned with WHO ICD-11 (6B06 Selective mutism), the American Speech-Language-Hearing Association (ASHA) on communication and anxiety, the American Academy of Pediatrics, and NICE guidance on childhood anxiety.
