This study aimed to investigate the effectiveness of peer mentoring of undergraduate education students enrolled in core curriculum, writing-intensive courses. The findings indicated that there were similarities and differences in what students and mentors considered to be important characteristics of a peer mentor. Both students and mentors said that knowledge in the field of writing and good communication skills were the most important characteristics of undergraduate peer mentors (UPM). The results revealed the major constructs of a peer mentor program that students found most beneficial. The students mentioned feeling more comfortable going to their peer mentor for help and feeling less intimidated than if they had asked their instructor. In addition, the findings on the UPMS indicated that participating in the UPM program resulted in several benefits to peer mentors as well.
