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.

This research was carried out to compare the academic performance of the Sixth-semester stadents of the new educatoonal system, who have been guided to enter one of the five priorities designated through the educational guidance program. The sample consisted of’ 624 students, selected randomly, from the educational districts ‘of the city of Ahvaz, Iran, who could enter any one of the five priorities. These students were selected from the three fields of emperical sciences, mathematics-physics, and humanities. The students’ GPAs of their 3rd, 4th, and 5th semesters were used as their general academic performance index. Their 5th semester GPA was also used as their specific performance index. One way ANOVA and t-test were the major statistical analyses in this research. The findings showed no significant differences in the general or specific performances of the students entering any one of the five priorities, except for the students in the emperical sciences field, with regard to their general performance index. However, follow-up pair comparisons did not detect any significant difference.
