Health Sciences University of Mongolia (HSUM) has been taking integrated examination (IE) on pre-medical subjects since academic year of 2008-2009. The purpose of the study was to analyze the integrated exam items for freshman students of Medical School, HSUM. The study design was descriptive, cross sectional. The study focused on the midterm grades of 5 different pre-medical subjects and results of 150 test items with 5 variations that were based on curriculum of the subjects. Furthermore, it focused on integration exam grades in which 343 students involved and the questionnaire results of the students who re-examined. Kuder-Richardson (KR20) formula was used to determine reliability coefficient and statistical method to determine discrimination index, the difficulty level. Collected data were analyzed using”SPSS-11.01”. Reliability coefficient of each subject’s exam in IE is varied 0.85-0.9 and according to the difficulty level (P-value) 21.3-35.3% of test items were categorized as an easy, 51-56%-moderate and 13.3-14.7%-difficult. Regarding to discrimination index of test items, 92-97.3% of them have positive discrimination index, which shows most of the items can discriminate examinees by their performance. The mean score of students in re-examination was higher than first exam. In the re-examination difficulty level was decreased and in the third it increased comparing to the re-exam test items. We concluded that IE is reliable; its test items can determine student’s performance and difficulty level in re-examination test items lower than the first exam. Based on the conclusion we recommend taking re-examination only once.
