Purpose - The purpose of this paper is to examine the impact of first generation peer mentoring experiences on retention, grade point average and students' perception of their academic and leadership development. Design/methodology/approach - This study utilized a mixed methods approach. Focus groups and interviews were utilized to determine the reported leadership experiences of the mentors. Descriptive statistics were used to compare grade point averages and retention rates. Findings - The study found peer mentors in residential life perceived an increase in leadership skills; including role modeling, time management, personal confidence, and problem solving. The peers were challenged in their roles, and perceived these challenges to help them to grow as leaders. When compared to their peers, the peer mentors experienced increased retention and similar grade point averages. The results indicated that peer mentoring experiences can be beneficial for the mentors who are first generation college students, even experiences that are particularly challenging. Research limitations/implications - The biggest limitation to this study is the fact that this was a small sample, without a control group. A further limitation is that it was difficult to get students to participate in the study. Future research might examine peer mentoring experiences of first generation students on larger campuses or on multiple campuses to allow for a control group of first generation peers without a peer mentoring experience. Practical implications - The results indicated that peer mentoring experiences can be beneficial for the mentors who are first generation college students, even experiences that are particularly challenging. Social implications - Due to the potential for their success, these types of experiences should be expanded for first generation students, a group that is at a higher risk for drop out. Special attention should be paid to ongoing training in peer mentoring experiences, given the level of commitment by the mentors. Originality/value - While other studies have examined the impact of peer mentoring on those that have been mentored, and a few have examined the impact of the experience on the mentors themselves this study extends the research by looking at first generation college students. This is valuable because first generation students continue to lag in their success in college and practical research on what can improve the student experience for this group is necessary.
