This study examined peer leaders' impact on peer student engagement and belonging at a minority-serving institution. The researcher conducted a quasi-experimental study examining the association between students' affiliation with peer leaders and their engagement level (measured by their participation at campus events), and their sense of belonging at a two-year, minority-serving institution. The two questions that guided the study were: (1) What is the difference between time spent with a peer leader on peer engagement at social campus events? (2) What is the difference between spending time with peer leaders on a peer student's sense of belonging to the institution? The findings revealed that peer leaders positively impact students' perceived peer support and classroom comfort. The results also showed that students who participated in the peer mentoring and leadership program had higher levels of engagement. This study was conducted because there was limited research on the relationship peer leaders had on peer engagement and a sense of belonging. This study's findings showed a significant relationship in engagement when associated with a peer leader at a two-year minority-serving institution. This research study was designed to contribute to the literature that informs higher education leaders' practices in increasing college completion rates.
