The Communication Sciences and Disorders (CSD) undergraduate program's initial coursework provides students with a thorough understanding of the scientific, developmental, and multicultural aspects of speech, language, and hearing. Upper division courses explore the nature, assessment, and treatment of various disorders of speech, language, and hearing, culminating in clinical practicum classes where students work directly with clients in the WIU Speech-Language-Hearing Clinic. CSD undergraduate class sizes average 30-35 students. CSD undergraduate students must complete general education requirements, 35 semester hours of "core courses" and nine semester hours in the major, 16 to 20 semester hours of approved minor, and electives or teacher certification course requirements for a minimum of 120 semester hours. Typically, CSD students enroll in clinical practicum for one or two semesters. While clinical experiences at most universities are reserved for graduate students, the undergraduate program at WIU takes pride in the fact that seniors will have their first clinical experience after completion of a 30 clock-hour observation program and completion of certain prerequisite courses and requirements.
