Official statistics from several resources in Iran indicate that female enrollment and achievement in Iranian universities has recently exceeded that of male students. Despite the fact that a religious government has been ruling the country for three decades, and despite many regulations against women, Iranian women have managed to overcome social, cultural, and political barriers. They have also been able to pass a highly competitive entry exam to enter the university at higher performance rates than male students. In this study it was proposed that this increasing enrollment and graduation rate might be attributed to their gender-based self-confidence and their self-efficacy. The results showed that female students scored higher on collective, gender-based self-confidence but their personal feeling about their gender was more negative and their general self-efficacy was not different from the self-efficacy of male students.
