This interactive session is designed for educational diagnosticians and speech-language pathologists who support emergent bilingual students during the special education evaluation process. Participants will examine the differences between language dominance and language proficiency and learn how to select and interpret relevant data sources. The session will focus on collaboration across evaluation teams. Practical strategies will be shared for ensuring consistency in the language of assessment throughout the FIIE, validating results when bilingual assessments are limited, and using evaluation outcomes to guide decisions about the language of instruction and therapy. This session is aligned with the Evaluation and Disproportionality - Identification and Placement components of the TEA-required self-assessment.
