Abstract
This study aimed at assessing the efficiency of the partial Credit Model, in Calibration of polytomous items for the purposes of the study, an achievement test in chemistry for the second secondary class was prepared. The test consisted of 20 polytomous items which differed in the number of steps in each item. The test was administered to a sample of 771 male and female students. Mor specifically, the follwing findings were of particular importance: 1. Item difficulty increased as the number of the item steps increased. 2. There were no statistically significant differences in estimates of a sample of 11 items selected from the test when calibrated in four different groups of student. 3. There were statistically significant differences in estimated ability between the random, the high ability and the low ability groups, based on a sample of difficulty items and a sample of easy items. 4. The relative efficiency of the test increased in general when the number of the item steps increased 5. The relative efficiency of the difficult test compared to the total test was equal to one in the high ability group. However, the relative efficiency of the easy test compared to the total test in-creased in the low ability group. Based on the findings of the study, a number of recommendations were proposed
