Developmental Language Disorder and the Assessment of Spoken Language

Abstract

Developmental language disorder (DLD), previously known as specific language impairment (SLI), is a long-term developmental disorder affecting approximately 7.5% of children. Language abilities in children with DLD are variable and can be challenging to ascertain with confidence. This chapter aims to discuss some of the challenges associated with assessing the language skills of children with DLD through an overview of different forms of language assessment including standardized language testing, language sample analysis, and observations. Uses and limitations of the different forms of assessment are considered, bearing in mind the different functions of assessment and the need to gain a full understanding of children’s profiles of strength and weakness and communicative functioning in context. The authors conclude with requirements for best practice in assessment and promising avenues of development in this area.
