As an important strategy to promote the quality of teaching, the faculty member's assessment has been seriously taken into consideration by universities. The purpose of the present study was to compare the student's assessment of the faculty members and self-evaluation. In this cross sectional descriptive analytic study, 885 students and 49 faculty members participated in this study in the second semester in 2009-2010. The maximum of 20 students were considered for the evaluation of each teacher. The instrument of data collection comprised of two corresponding questionnaires that were prepared based on Likert scale and included demographic information and teaching methodology. Data were analyzed by SPSS 16 software using descriptive statistics (independent T-test and ANOVA). The mean of scores for the faculty member's self-assessment was 88.12 ± 6.21 out of 100 and the mean of scores for the student's assessment was 79.33 ± 8.25 out of 100 that was statistically significantly differently from each other (p=0.021). There was a significant difference between the two groups in most cases regarding the 20 questions of the questionnaire.
