A Multidiscipline Study of Education Program Accreditation Type and Certification Exam Performance.

Objective: To examine the relationship between radiologic technologists' performance on 3 medical certification exams and the type of accredited education program they attended.

Methods: Data came from 3 certification exam programs administered by the American Registry of Radiologic Technologists (ARRT). The author used simple means and mixed-effect models to analyze 13 years of data.

Results: The difference in performance between programs with and without programmatic accreditation, as modeled with linear mixed-effect models, amounted to approximately 2 exam questions out of 200 for radiography, no difference for nuclear medicine technology, and approximately 4 questions out of 200 for radiation therapy.

Conclusions: Exam performance differences among the accreditation types were not large, if they indeed existed, for ARRT certification exam data.
