Background and Objective: Regarding the importance of medical education development, it is imperative to determine the crucial factors which have influence on improvement of academic staff efficiency. Job satisfaction is one of the most important promoters among faculty members for enhancement of teaching quality. This study was conducted to evaluate this satisfaction among faculty members of Zanjan University of Medical Sciences (ZUMS).

Materials and Methods: In this descriptive-sectional study, research population consisted of basic science and clinical faculty members (instructor, assistant professor and associated professor) in 6 faculties of ZUMS in 2013. Data was collected through demographic as well as Herzberg job satisfaction 5-point Likert Scale questionnaire.

Results: Results demonstrated that 35.5% of faculty members' satisfaction score was low, 52.9 was moderate and only 11.9% was high. Satisfaction with nature of the work (82.1) was the uppermost, while salary and benefits were the lowest (41.6). Work place conditions (74.6), job security (53.1), supervision and relations (49.3), and promotion opportunities (45.3) were in the next steps respectively.

Conclusion: ZUMS faculty members were satisfied with nature of their work on the whole. However, by increasing their salaries and job benefits, academic staff efficiency can be improved.
