Popis: In theory, a competency-based medical school curriculum allows all students the prospect of answering every test question correctly. In practice, tests often include questions that may not assess core medical knowledge. A panel of five medical educators from diverse fields categorized the pre-clerkship multiple choice test questions as either core or supplemental. Core questions that were deemed essential for completion of the medical curriculum, licensing exams, or the practice of medicine were classified as core questions (C). The panel determined that the majority (85.9 %) of the questions tested essential medical knowledge (C) while a smaller percentage (14.1 %) tested material that was important but not essential to medical education, termed supplemental questions (S). Supplemental questions were found to be more difficult to answer and had a higher discriminative ability. Thus, these questions better differentiated strong performers from weak performers. This suggests that while core question performance measures whether students have met levels of basic knowledge competency, inclusion of supplemental questions may allow us to recognize academic excellence and may represent an additional variable when considering students in the resident selection process.
