Evidence-Based Therapy Plan for Selective Mutism

A child who speaks freely at home yet falls silent at school is not being defiant — they are caught in anxiety, and the plan that frees them is gentle, graded and consistent.

In short

An evidence-based plan for Selective Mutism (ICD-11 6B06) is rooted in behavioural anxiety treatment — graded exposure to speaking demands, stimulus fading and shaping — delivered collaboratively across home, school and clinic. The aim is not to make the child talk but to systematically lower the anxiety that blocks speech, so verbal communication generalises naturally across settings. Early, coordinated intervention carries the best prognosis.

What the plan includes

• Functional assessment mapping where, with whom and under what conditions speech occurs and fails — anxiety, not capacity, is the target.
• Stimulus fading — beginning with a person and setting where the child already speaks, then incrementally introducing new people and contexts.
• Shaping and successive approximations — reinforcing communicative steps from gesture and mouthing to whispered words to audible speech.
• Graded exposure with a collaboratively built hierarchy, removing pressure and avoiding direct questioning early on.
• Contingency management — positive reinforcement for brave communication; never coercion or bribery.
• School and family as co-therapists — the classroom is the primary generalisation arena, so teachers and parents are trained partners, not observers.
• Liaison for co-occurring social anxiety or speech-language difficulty where indicated.

Pharmacotherapy (e.g. SSRIs) is considered only in older or severe, refractory cases under specialist psychiatric care — behavioural intervention remains first-line in young children.

The Pinnacle way

Any diagnosis and a clinical AbilityScore® are established only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a form or an app. From there your team builds a graded plan for selective mutism, draws on targeted speech therapy, and tracks progress against a clinician-administered AbilityScore® baseline.
