Background: students are exposed to stress for many reasons and there are situations which they need guidance. Mentorship programs have been successful in managing these situations. These programs are one of the main university tasks, which sometimes get less attention which affects its performance. The study aim is to determine the mentor's performance from students view in Alborz University of medical sciences.

Methods: In a cross-sectional design, 304 students randomly entered to the study. A self administrated questionnaire were used after reliability and validity been confirmed. Independent-T Test, one way ANOVA and bonferroni post hoc, and Chi-square tests were used for data analysis.

Results: Mean performance score was 78.53(±22.54) which assumed as to be moderate performance. The score was different between different fields of study (P<0.0001). There was no significant difference by mentor's or student's gender; however the performance score were higher when mentor and student had same sex (P<0.042).   52.6% were satisfied of having a mentorship program in the university. Groups that had more visits had higher satisfaction rates (P<0.0001) but their mean performance score was lower (P<0.0001).

Conclusion: It is necessary to identify and resolve barriers of proper mentorship program running. Measures and incentives to make mentors put sufficient time   and also strategies to increase students' participation in selecting their mentors, the professor, students and mentors having, using of higher grade students to help new students under supervision of mentor must be considered. It is needed to survey program performance in medical universities by the Ministry of Health using a similar and standard instrument.
