One of the ways to increase efficiency and effectiveness of universities is performance evaluation of its various dimensions. In the past decade, with the reduction of social demand for higher education affected by quantitative expansion of universities, educational planners have been focused on analysis and evaluation of higher education quality. Considering students’ opinions, as main customers of this system, about university lecturers’ performances could be a good point of reference for understanding the conditions governing the quality of universities. The main purpose of the present study is to determine the relationship between faculty members’ social popularity with their evaluation by students at the University of Lorestan. A sample of 500 students from all colleges of University of Lorestan was selected by Stratified Random Sampling Method. Data was gathered by a researcher-made questionnaire with 30 questions and a ready questionnaire with 15 questions using a five-point Likert Scale. Content validity of the questionnaires was determined by university faculty members and their reliabilities by Cronbach’s alpha. The first findings of the study confirmed that there is a positive and significant correlation between the two variables of social popularity of university lecturers and their scientific evaluation by students. Other research findings confirm that academic ability in comparison with teaching ability can vary and be explained by changes to the social popularity of faculty members. Furthermore, among different components of social popularity, relational and managerial validity have more impact on university lecturers’ popularity.
