In this paper, an analysis was presented based on ordinal logistic regression that illustrates what is the relationship between “expert judges”(or student) and influencing factors of item difficulty. The results of the study show that test purpose and cognitive skills primarily influence “expert judges”. However, the patterns shown by the student data are effectiveness of the incorrect alternative responses, connective between current practice and test content, negative questions mostly influence students. Although work from this study is limited, it suggests that the prediction item difficulty will fare well when relevant studies are conducted.
