PurposeThis paper presents a case study for the pilot of a peer-led service model that is centered on fostering student leadership, collaboration and advocacy. The authors, who serve as advisors to the program, discuss the Library's transition to this peer-led model for reference support, outreach, programming and campus engagement.Design/methodology/approachThis case study examines the development and implementation of a new peer-led service at a mid-size public university aimed at centering student success, belonging and empowerment. Authors share practices, strategies and goals for training, onboarding and professional development with emphasis on student advocacy, leadership and retention in the program.FindingsThe authors found that developing the structures and opportunities to foster student-led initiatives and efforts for student success, belonging and engagement has helped the library better connect and engage with diverse student communities on campus.Research limitations/implicationsFindings of this study may be limited at the time this case study is written due to it being a new and developing library student program for reference, outreach and programming.Practical implicationsThe peer-led service model for reference and student engagement presented in this article serves as a case study that may be applicable for those who wish to imagine and develop a student-centered library program at their institution.Social implicationsThis case study may provide an alternative approach useful to those who wish to reimagine and innovate library student programs at their institutions.Originality/valueAlthough there are many peer-led initiatives in academic libraries for outreach and programming, this program explores the approach of fostering student leadership and advocacy within library student roles to lead and facilitate library efforts for campus engagement with structured guidance and support from librarian advisors.
