MBE questions are developed by drafting committees composed of recognized experts in the various subject areas. Before a test question is selected for inclusion in the MBE, it undergoes a multistage review process over the course of several years. Besides intensive review by the drafting committee members and testing specialists, each test question is reviewed by other national and state experts. All test questions must successfully pass all reviews before they are included in the MBE. After an MBE is administered, the performance of each test question is reviewed and evaluated by content and testing experts. This final review is conducted to ensure that the exam is graded fairly, particularly with regard to any questions affected by recent changes in the law.
