Subjects and methods: The database used in this study corresponds to the answers to the questions of the MIR exam of 2015 of a total of 3,712 examinees. Results: The average rate of difficulty of all questions was 0.6882, while the corrected index of difficulty was 0.5422, the discrimination of 0.2492 and 0.2954 the value of the point biserial correlation. The formula number 21 of Kuder-Richardson and the Cronbach's alpha were also applied giving as results 0.9459 and 0.9579 respectively. These values were compared with those obtained for the MIR test in the range from the calls 1989 to 1993.
