Scale scoring allows scores from the same specialty exam to be compared between exam versions, forms, and cohorts. However, scores can only be compared within each specialty exam, not between specialty exams.
While you cannot directly compare total scale scores between specialty exams, you can look at subscores from similar content areas for program evaluation. Trends can be analyzed in content and task areas between exams for those areas that appear on multiple exams. For example, if subscores in endocrinology are consistently low across many of the End of Rotations exams, you may want to reflect back on your curriculum and determine if endocrinology is covered in sufficient detail during the didactic phase of the program. This provides valuable data to ensure your program is meeting its objectives.
