Accurate and timely identification of reading disabilities (RDs) is essential for providing appropriate and effective remediation for struggling readers. However, practices for identifying RDs lack sufficient documentation within and across educational and clinical settings. The wide range of possible practices intended to identify struggling readers can render the field vulnerable to inconsistencies in how the needs of struggling readers are recognized and supported. To better understand the range of current practices used to identify RDs in school-age children, we created and disseminated a survey nationally, and analyzed data from 965 practitioners. The findings indicate lengthy timelines to identify RDs; substantial variability in the composition of assessment teams, identification criteria, and diagnostic labels; and notable opportunities for enhancing practitioner training experiences. This study aims to promote cross-contextual dialogue about the identification of RDs and their implications for students' educational experiences.
