Rare is the layperson who has heard of Developmental Language Disorder (DLD). This is not because DLD is rare or inconsequential. In the United States, DLD is 50 times more prevalent than hearing impairment and five times more prevalent than autism (Centers for Disease Control and Prevention, 2015). Children with DLD are considerably slower than other children to develop spoken vocabulary and grammar despite normal intelligence and ample opportunity. DLD is a life-long condition (Nippold & Schwarz, 2002) that impairs social (Botting & Conti‐Ramsden, 2008) and academic (Alloway, & Stein, 2014) functions.
