Research and analysis

Prospective cohort study of speech and language therapy services for young children who stammer in England

The aims of this study were to investigate the outcomes for children under the age of 7 years referred to speech and language therapy (SLT) services for help with their stammering, to identify what intervention was delivered and any factors that influenced treatment implementation and outcome.


The Better Communication Research Programme (BCRP) was commissioned as part of the Better Communication Action Plan, the government’s response to the Bercow review of services for children and young people with speech, language and communication needs.

This report concerns young children who stammer or stutter: the terms are synonymous. These children have disorders with the fluency and rhythm of speech, but are rarely categorised as having special educational needs or disabilities on the basis of their stammer alone. Nonetheless, children who stammer may have difficulties managing their learning in classrooms in ways that are directly related to stammering; for example, they may find it difficult to ask or respond to questions in class.
