In the present study, comparability of scores from student evaluation of teaching forms were investigated. Checking comparability is of importance since scores given by students are used in decision making in higher education institutions. To this end, three course-related variables (grade level, course type and credit) were used to define student subgroups. Then, confirmatory factor analysis approach was used to assess invariance of factorial structure, factor loadings and means across groups. It was found that although a common factor structure hold across groups, invariant factor loadings were observed only across instructors who teach different course type, elective and must. For other groups, only partial invariance was obtained. Analyses also revealed that none of the subgroups had invariant factor means. Results indicate that comparison of instructors based on student ratings may not be reliable as much as it is assumed.
