textChildren with Down syndrome present with an array of physical and cognitive sequelae that can hinder speech and language development. These individuals can constitute a considerable portion of a speech-language pathologist’s caseload. Based on the principles of best evidence, clinicians are ethically responsible for providing the most effective treatment for their clients. The available literature focuses mainly on describing the linguistic characteristics in this population, while relatively less focus is placed on effective intervention programs. This paper investigates the available evidence regarding speech and language interventions for children with Down syndrome who are in the mild to moderate range of linguistic functioning, and provides an outlook for future research based on best evidence.Communication Sciences and Disorder
