Purpose:
This study aims to compare the various standard setting methods for the Korean Radiological Technologist Licensing Examination with the fixed cut score and suggest the most appropriate method.
Methods:
Six radiological technology professors, set the standards of 250 items for Korean Radiological Technologist Licensing examination that were conducted on December 2016 by using Angoff, Ebel, bookmark, and Hofstee methods.
Results:
With the maximum percentile score of 100, the cut score for the examination was 71.27 in Angoff method, 62.2 in Ebel method, 64.49 in bookmark method, and 62 in Hofstee. Based on the Hofstee's acceptable cut score, the acceptable cut score for the examination was between 52.83 and 70, but the cut score was 71.27 in Angoff method.
Conclusion:
Above results suggested that the best standard setting methods to determine the cut score was panel discussion with the modified Angoff or Ebel methods, and verification of the rated results by Hofstee method. Because there was still no adoption of standard setting in the Korean Radiological Technologist Licensing Examination, this study will be able to provide the practical guideline to introduce the standard setting.
