Statistically speaking, an average primary school will have children who stammer - if you do not know them, they have managed to hide their stammer.
There is no single cause, although there may be a genetic link. There is no single or definite cure and there is no single best strategy for supporting pupils. Current research indicates that the cause of stammering has a physiological basis in the brain structure.
It varies in severity and a child may have fluent periods and then revert to stammering for no apparent reason.
There is no evidence that children who stammer differ in anyway way psychologically or in intelligence from their non-stammering peers - therefore never underestimate potential.
Make a sensitive judgement about the language demands on the child and avoid complex oral tasks when the stammer is severe. Introduce more complex tasks when the child feels more confident and is able to accept more demands on his speech, so that his potential for language development is maximised.
