CDIS 5690. Clinical Externship II in Communication Disorders.

This course is the second of two required off-campus clinical placements and evaluates the application of foundational knowledge and clinical competencies in speech-language pathology within community-based practicum settings. Students investigate the processes of assessment, treatment planning, documentation, and therapeutic service delivery under the direct supervision of licensed speech-language pathologists. Emphasis is placed on analyzing clinical decision-making, applying evidence-based methodologies, and integrating theoretical frameworks into professional practice. Through structured supervision and reflective analysis, students enhance their ability to evaluate intervention outcomes and professional communication with increasing independence in authentic clinical contexts. Prerequisite: CDIS 5689 with a grade of "CR".
