What an AbilityScore of 300–400 Means in Selective Mutism
An AbilityScore of 300–400 is a clinician-captured snapshot, not a label — typically a child who speaks freely at home but stays silent in specific settings like school. It is a baseline to measure progress against, and Selective Mutism responds well to gentle, graded support.
In this answer 5 sections
When your child speaks freely at home but falls silent at school, a number can feel daunting — so let's make this band mean something hopeful and practical.
In short
An AbilityScore® in the 300–400 band is one snapshot, captured by a clinician, of where your child is right now with Selective Mutism — typically describing a child who communicates comfortably in safe settings (often home) but consistently cannot speak in specific social situations such as school. It is a starting baseline to measure progress against, never a label or a ceiling. With the right gentle, gradual support, children move through and beyond this band.
What this band tends to reflect
Selective Mutism (ICD-11 6B06) is best understood as an anxiety-based difficulty, not defiance, shyness alone, or a choice. A score in this range usually points to:
- Strong home communication — your child talks, plays and expresses freely with trusted people.
- Situation-specific silence — speech reliably drops away at school, with unfamiliar adults, or in groups.
- Communication that is present but routed differently — gestures, nodding, pointing or whispering may be doing the talking.
The band helps your clinician and your child's therapist see where the anxiety locks speech, and plan the smallest, kindest next step to widen the circle of places your child feels safe to speak.
Why a single number is only the beginning
Development moves in steps and plateaus, not straight lines. One score cannot capture a whole child — which is exactly why it is re-measured over time against your child's own earlier baseline, so quiet, real progress becomes visible. Selective Mutism responds well to graded, low-pressure approaches; the band you start in is far less important than the direction you move.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online form or a number alone. Our approach pairs a speech and communication programme with anxiety-sensitive techniques that never force speech, and tracks your child against their own AbilityScore® baseline. With 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, the aim stays the same: your child finding their voice, at their pace.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch whether the circle of safe-to-speak situations is widening — a whispered word to a new adult, speaking in a smaller group, or talking at the school gate. Seek a review sooner if your child stops speaking in places they previously spoke, or shows rising distress, withdrawal or refusal to attend school.
In everyday life
Lower the pressure on speech: ask fewer direct questions and create relaxed side-by-side play where talking is welcome but never required. Celebrate any communication — a gesture, a nod, a whisper — warmly and without making a fuss, so your child feels safe enough for words to follow.
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 an AbilityScore of 300–400 a diagnosis of Selective Mutism?
No. The AbilityScore® is a clinician-administered structured snapshot of where your child is right now — a baseline to measure progress against. A diagnosis is formed only at a Pinnacle Blooms Network centre under qualified clinician care, never from a number or an online form.
Can my child move out of this band?
Yes. The band describes where your child is today, not a ceiling. Selective Mutism is anxiety-based and responds well to gentle, graded support that never forces speech, and the score is re-measured over time against your child's own earlier baseline so progress stays visible.
Why does my child talk at home but not at school?
This is the hallmark of Selective Mutism (ICD-11 6B06) — an anxiety-based difficulty, not defiance or shyness alone. Speech reliably flows in safe, familiar settings and locks up in specific social situations. The goal of therapy is to gently widen the circle of places your child feels safe to speak.
