MPRE Scoring
The MPRE scaled score is a standard score. Standard scaled scores range from 50 (low) to 150 (high). The mean (average) scaled score was established at 100, based upon the performance of the examinees who took the MPRE in March 1999.
The conversion of raw scores to scaled scores involves a statistical process that adjusts for variations in the difficulty of different forms of the examination so that any particular scaled score will represent the same level of knowledge from test to test. For instance, if a test is more difficult than previous tests, then the scaled scores on that test will be adjusted upward to account for this difference. If a test is easier than previous tests, then the scaled scores on the test will be adjusted downward to account for this difference. The purpose of these adjustments is to help ensure that no examinee is unfairly penalized or rewarded for taking a more or less difficult form of the test.
