The purpose of this study was first to measure the psychometric characteristics of Shahid Chamran University faculty members’ final test papers. The investigation of different test formats and different procedures used by faculty members to evaluate their students final academic performances also served as a second purpose of this study. A total of 109 faculty members from different academic disciplines voluntarily participated in this study. Each test item on exam papers was analyzed individually and its item difficulty, item discrimination and index of reliability were computed. The results of the completed analysis of test items were confidentially sent to the faculty members. The findings of the study showed that faculty members differ in the test format they use to evaluate their students academic performances. By comparing the psychometric characteristics of the test items with the known criterions, it was found that the differences between faculty members were significant. In addition, the analysis of item diffculty of the test papers showed that the students did not have a hard time answering the test items which means that the test items were relatively easy. It is therefore suggested that the university provide a testing center in which the faculty members would be able to learn how to construct standardized tests and improve their understanding in calculating the psychometric characteristics of their test scores.
