On the Many Terms for Developmental Language and Learning Impairments

The terms Language Disorder, Developmental Language Disorder (DLD), Language-based learning disabilities, Specific Learning Disorder, and Specific Learning Disability are commonly used to describe children struggling to learn at school. In this position paper, the definitions and distinctions between these terms are discussed, and key overlaps and differences described. Although often used interchangeably, Specific Learning Disorder and Specific Learning Disability are not synonymous. Based on current definitions, DLD and Specific Learning Disorder are related to Specific Learning Disability in the same way. In educational settings, children with DLD may additionally be identified using terms such as Language Impairment, Speech, Language, Communication Needs (SLCN), and others. Despite the problematic overlap in the names Specific Learning Disorder and Specific Learning Disability, one advantage of the latter term is the acknowledgment that many skills underlying academic learning are language-based, thereby capturing the disability experienced by children with language or academic learning disorders.
