Selective Mutism in Hong Kong Schools: The Child Who Won't Speak English in Class

The referral usually reads something like: "refuses to speak in English class." Sometimes: "will not speak at all at school." Sometimes, more specifically: "speaks perfectly normally with family at home but becomes silent the moment she enters the school building."

The parent sometimes adds: "We don't understand it. Her English is fine. She talks constantly at home. We don't know what happens to her at school."

What happens is selective mutism. And selective mutism is one of the most consistently misunderstood presentations I work with — misunderstood by schools, by families, and sometimes by professionals who are not familiar with it.

What selective mutism actually is

Selective mutism is an anxiety disorder. It is not defiance. It is not stubbornness. It is not a decision that a child makes consciously. It is the result of an anxiety response that becomes so associated with specific contexts — usually school, usually any social context outside the home — that speech becomes physiologically impossible in those contexts.

The key word is impossible. Not difficult. Not unlikely. For many children with selective mutism, the command to speak in the triggering context produces the same kind of neurological lock that happens in any extreme anxiety state. You cannot speak any more than you can walk when your leg is asleep. The system is frozen.

This is important to understand because the common school response — gentle encouragement, waiting for the child to speak, increasing social pressure to respond — is exactly the wrong intervention. It increases the anxiety, which increases the freezing. Children with selective mutism who are waited out or pressured into speaking do not overcome their anxiety; they develop secondary shame about the mutism, which complicates everything further.

Why Hong Kong is a particular environment for this

Selective mutism occurs in all countries and contexts, but Hong Kong's bilingual educational environment creates conditions that are particularly likely to produce it in children who have underlying anxiety tendencies.

Consider the situation from the child's perspective: they are in a context where two languages are expected, where one of those languages (English) is not spoken at home, where performance in both languages is assessed and visible, and where the classroom is an inherently high-stakes evaluative environment. For a child with a temperament that is anxiety-prone, sensitive to social evaluation, and highly attuned to the possibility of being wrong in front of others, this is a great deal to manage.

Add to this the specific dynamics of second-language English in Hong Kong: many children do not speak English at home at all, so their English production exists only in the school context. If the school context becomes associated with anxiety early — and for some children this happens very quickly, sometimes in the first weeks of schooling — the English production gets frozen along with everything else.

What I sometimes see is a child who has developed selective mutism specifically in English but can speak Cantonese at school with less difficulty. The mutism has attached itself to the second language, which was always more fragile, always more associated with performance and evaluation, never embedded in the safety of home.

What families can do

If you suspect your child may have selective mutism — they speak normally at home but become silent in school or other social contexts — the first and most important step is professional assessment. Selective mutism requires a qualified mental health professional to diagnose and treat; the approaches that help are specific, and misapplied interventions can make things significantly worse.

While you are seeking assessment or waiting for an appointment, there are several things that are helpful and several that are not.

What helps: maintaining warmth and normalcy around the mutism. Avoid expressing distress about the silence, as this communicates that the silence is a serious problem, which increases the shame and anxiety. Avoid asking the child directly why they don't speak at school — they do not know why, and the question implies they should know, which is its own pressure. Celebrate home speech freely; the home should remain a context of total communicative safety.

What does not help: incentive schemes where the child gets rewards for speaking at school. This increases performance pressure and does not address the underlying anxiety. Similarly: forcing verbal responses, putting the child on the spot, having school staff "work on" getting the child to speak without a coordinated therapeutic approach.

What I do in therapy

My work with selectively mute children begins at the far end of where they are comfortable and moves very, very slowly toward the difficult contexts. This is called a graduated exposure approach, and in selective mutism, graduated means genuinely graduated — small steps over a long timeline.

We might begin with the child and I in the room together, communicating entirely non-verbally through play. No expectation of speech. Weeks of this, if needed, until the room is thoroughly associated with safety. Then, gradually: a whisper. Then speech in a whisper to a trusted adult. Then, eventually, normal speech in the room. This is all still within the therapy space, with one trusted adult.

From there, with great care, we begin to extend the safe context — introducing a second person the child trusts, then moving to a different but safe location, then, much later, to contexts that approach school.

This process takes months. It cannot be rushed. The anxiety has to genuinely reduce through accumulated safe experience; there is no shortcut.

For teachers

If you have a child in your class who is selectively mute, the most valuable thing you can do is create the maximum possible space for that child to participate without speech. Nods, written responses, pointing, drawing — all forms of communication that allow participation without triggering the freeze response. Never cold-call a selectively mute child. Arrange the classroom so that the child has maximum proximity to a trusted peer.

And please, in your conversations with parents and school support staff, frame the child's silence as what it is: anxiety, not attitude. The child who will not speak English in your classroom is not being difficult. They are frightened, deeply and genuinely, in a way that you cannot see and they cannot explain.

They need safety before they can speak. Once they have safety, the words usually come.
