The paper describes the computer system for the evaluation of test examinations organized by Centre for Examinations in Medicine. The system consists of the optical mark reader (OMR) and originally developed Windows-based application. The application supports up to 600 multiple choice questions with 4 or 5 answers to choose from. There can be two versions of test with the same questions in different orders. After reading the cards, necessary checks are performed (e.g. for multiple or missing answers). The application allows to efficiently input necessary corrections and then to calculate the individual scores. The statistical features of the whole test are also calculated (including KR20, mean difficulty index, mean discrimination index) as well as characteristics of every question, including its difficulty and point biserial correlation coefficients.
