Developmental Language Disorder (DLD)

Developmental Language Disorder (DLD) is the new term to replace Specific Language Impairment (SLI).

Developmental Language Disorder is diagnosed when children fail to acquire their own language for no obvious reason. This results in children who have difficulty understanding what people say to them, and struggle to articulate their ideas and feelings. Recent research has shown that, on average, 2 children in every class of 30 will experience DLD severe enough to hinder academic progress.

In 2017, the first DLD awareness campaign was introduced with the theme DLD123 highlighting (1) DLD is a problem with speaking and/or listening, (2) it is hidden but common, and (3) support can help to improve the quality of life of affected children and their families.
