Team-based learning (TBL) is a highly structured method of active small group learning and consists of identical tests taken individually and in groups. We reviewed literature to determine the scoring methods used for individual and group testing. Twenty-eight percent of the studies used multiple choice formats for the individual test and formats that allow for immediate feedback and corrective scoring for the group test. We calculated the expected value of both individual and group tests and found that by default groups will score higher than individuals, even if there is no actual difference in performance. We urge TBL practitioners to use statistically equivalent scoring for individual and group testing.
