It is an anxiety-based difficulty — children want to speak but feel unable to in certain settings — and responds well to gentle support. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*When a child speaks freely at home yet falls silent at school, it isn't shyness or defiance — it's a recognised anxiety-based difficulty, and you are far from alone.*\n\n## In short\nSelective Mutism is **uncommon but not rare** — most estimates place it at roughly **1 in 140 children (under 1%)**, with some studies in school settings reporting figures a little higher. It is seen slightly more often in girls, and it tends to become noticeable when a child starts nursery or school, where the expectation to speak in new settings first appears. It is an *anxiety-based* difficulty — these children genuinely *want* to speak but feel unable to in certain situations — and with the right understanding and support, the outlook is very encouraging.\n\n## Understanding the numbers\n- **Prevalence:** widely cited as **about 0.7–0.8%** of children — close to 1 in 140 — though numbers vary because the condition is often under-recognised and quietly mistaken for ordinary shyness.\n- **When it shows:** it most commonly emerges between **ages 3 and 6**, when a child meets settings outside the family. A diagnosis is usually considered only once the difficulty has lasted more than a month and isn't simply the normal settling-in period of a new school.\n- **The pattern that matters:** a child speaks comfortably and often a great deal at home, yet is consistently unable to speak in specific situations such as the classroom — despite having the language ability to do so.\n- **It rarely travels alone:** it frequently sits alongside social anxiety, and supporting that underlying anxiety is central to helping a child find their voice.\n\nBecause it is genuinely uncommon, many families spend a long time wondering what is happening — knowing it is a real, named, treatable condition is often the first relief.\n\n## When to seek a check\nSeek a friendly developmental check if your child consistently does not speak in certain settings (school, with relatives, in shops) for **more than a month**, while speaking freely elsewhere — especially once the first few weeks of a new setting have passed. Early, gentle support tends to bring the best results, so there is no need to wait and see for long.\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 online form. Our clinicians look gently at the whole picture — communication, anxiety and the situations that trigger silence — through a [clinician-administered structured assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated), then shape calm, confidence-building [speech and language therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) around your child. Begin by [exploring what support looks like](/).\n\n## Trusted sources\nWHO ICD-11 classification of Selective Mutism within anxiety and fear-related disorders; American Speech-Language-Hearing Association guidance on selective mutism and childhood communication; American Academy of Pediatrics (HealthyChildren.org) guidance on childhood anxiety.\n\n**Next step —** Wondering if what you're seeing is Selective Mutism? [Book a gentle assessment with a Pinnacle clinician](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/how-common-is-selective-mutism-in-children","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
