Graduate programs in speech-language pathology continue to experience high volumes of applicants seeking admission. There appear to be as many configurations of admission criteria as there are graduate programs. Yet, what evidence do we have for these criteria making a difference in graduate student outcome? Graduate Record Examination (GRE) scores, undergraduate grade point average (GPA), prerequisite GPA, letters of recommendation, and letters of intent are valued differently by programs. These variables were investigated for their value in predicting successful graduate school outcome in a program of speech-language pathology. Three measures proved predictive: the verbal portion of the GRE, the quantitative portion of the GRE, and the grade in the speech and language development course taken prior to admission.
