The MPRE is developed by a drafting committee composed of recognized experts in the area of professional responsibility. Before a test question is selected for inclusion in the MPRE, it undergoes a multistage review process that occurs over the course of several years. Besides intensive review by the drafting committee and testing specialists, each test question is reviewed by other experts. All test questions must successfully pass all reviews before they are included in the MPRE. After an MPRE is administered, the statistical performance of each test question is reviewed and evaluated by content and testing experts before the questions are included in the computation of candidates' final scores. This final statistical review is conducted to ensure that each test question is accurate and psychometrically sound.
