Accepting applicants with the highest probability of success is a priority for admission committees in institutions of higher education. For programs with limited capacity, selecting candidates with the greatest potential for successful completion of the program and becoming eligible for employment is crucial. Admission criteria that best predicts success is essential for both the program and the potential student in making admissions decisions. The aim of this study was to contribute to the value of admission criteria specifically in radiologic science educational programs. Specifically, to explore the relationships between program admission variables, institutional characteristics, and student success as defined by the Joint Review Committee on Education in Radiologic Technology (JRCERT) program effectiveness criteria. This included first-time pass rate on the certification examination administered by the American Registry of Radiologic Technologist (ARRT), program completion rate, and employment rate. The study population was comprised of all 437 associate degree granting radiography programs listed as accredited by the JRCERT. All of the data gathered for this study were publicly available through the JRCERT database, program and/or institution website, or the NCES College Navigator website. Key findings of admission criteria identified the use of an interview to predict employment rate and first-time pass rate on the ARRT certification examination. This study also identified that a larger number of required prerequisite courses predicts higher program completion rate. For institutional characteristics, smaller schools have higher pass rates. In addition, an open admission policy results in a lower program completion rate. [The dissertation citations contained here are published with the permission of ProQuest LLC.
