Prologue: Toward Accurate Identification of Developmental Language Disorder Within Linguistically Diverse Schools.

Purpose: Although the 5 studies presented within this clinical forum include children who differ widely in locality, language learning profile, and age, all were motivated by a desire to improve the accuracy at which developmental language disorder is identified within linguistically diverse schools. The purpose of this prologue is to introduce the readers to a conceptual framework that unites the studies while also highlighting the approaches and methods each research team is pursuing to improve assessment outcomes within their respective linguistically diverse community. Method: A disorder within diversity framework is presented to replace previous difference vs. disorder approaches. Then, the 5 studies within the forum are reviewed by clinical question, type of tool(s), and analytical approach.
Conclusion: Across studies of different linguistically diverse groups, research teams are seeking answers to similar questions about child language screening and diagnostic practices, using similar analytical approaches to answer their questions, and finding promising results with tools focused on morphosyntax. More studies that are modeled after or designed to extend those in this forum are needed to improve the accuracy at which developmental language disorder is identified.
