Validation of the Proficiency Examination for Diagnostic Radiologic Technology. Final Report.
Educational Testing Service, Princeton, NJ.
The validity of the Proficiency Examination for Diagnostic Radiologic Technology was investigated, using 140 radiologic technologists who took both the written Proficiency Examination and a performance test. As an additional criterion measure of job proficiency, supervisors' assessments were obtained for 128 of the technologists. The resulting data indicated that the total score on the Proficiency Examination was a valid indicator of overall job proficiency for radiologic technologists, and that separate subscores do not provide additional valid information about proficiency in the specific skill areas of radiation protection, patient care, technique and quality control, and positioning. The effects of using a pass/fail cutoff at several selected levels were also investigated. The results indicated that any cutoff between 45 and 75 percent of the total possible score on the Proficiency Examination will produce systematic differences in actual performance between the groups passing and failing the Proficiency Examination.
