Performance of the Ebel standard-setting method for the spring 2019 Royal College of Physicians and Surgeons of Canada internal medicine certification examination consisting of multiple-choice questions

This study aimed to assess the performance of the Ebel standard-setting method for the spring 2019 Royal College of Physicians and Surgeons of Canada internal medicine certification examination consisting of multiple-choice questions. Specifically, the following parameters were evaluated: inter-rater agreement, the correlations between Ebel scores and item facility indices, the impact of raters’ knowledge of correct answers on the Ebel score, and the effects of raters’ specialty on inter-rater agreement and Ebel scores. Data were drawn from a Royal College of Physicians and Surgeons of Canada certification exam. The Ebel method was applied to 203 multiple-choice questions by 49 raters. Facility indices came from 194 candidates.
