MBE Scoring
MBE answer sheets are scanned and centrally scored. Both a raw score and a scaled score is computed for each examinee. A raw score is the number of questions answered correctly. Raw scores from different administrations of the MBE are not comparable, primarily due to differences in the difficulty of the questions from one administration to the next. The statistical process of equating adjusts for variations in the difficulty of the questions, producing scaled scores that represent the same level of performance across all MBE administrations. For instance, if the questions appearing on the July MBE were more difficult than those appearing on the February MBE, then the scaled scores for the July MBE would be adjusted upward to account for this difference. These adjustments ensure that no examinee is unfairly penalized or rewarded for taking a more or less difficult exam.
