In this report, we summarize research on the identification of SLD and make recommendations for practice. The report begins with a summary of the legal requirements for SLD identification and what constitutes a comprehensive evaluation. It then discusses the attributes of SLD according to different conceptual frameworks and reviews research on the reliability and validity of different methods for SLD identification that emanate from these frameworks. The report concludes with recommendations for best practice, regardless of the specific identification methods employed.
