The purpose of this study was to examine how undergraduate peer mentors at Texas A&M University perceive their development of leadership behaviors through their peer mentor experience. Participants were first-generation college students serving as mentors to first-generation college students at Texas A&M University. A qualitative approach was used to examine reflections from the peer mentors about their personal best leadership experiences as a peer mentor and their self-reported highest scored practice on the Student Leadership Practices Inventory (SLPI). This study is rooted in Kouzes and Posner's (1987, 2002) Five Practices of Exemplary Leadership model. There were 33 peer mentors who participated in this study. Mentor reflections showed evidence of behaviors demonstrating all five of the exemplary leadership practices through serving as a peer mentor.
