With the objective of addressing declining university retention rates, the Sherrod Library at East Tennessee State University (ETSU) developed a peer-mentoring program in 2017. The Library Ambassador Program entails hiring undergraduates each fall and offering them two semesters of information literacy training. In their third semester, ambassadors are deployed across campus to help students with research. This presentation will discuss ETSU’s Library Ambassador Program as it moves into its second year and the lessons learned along the way. Participants wishing to create their own peer-mentoring program will come away with practical advice on developing a timeline for implementation, handling the day-to-day logistics of student workers and designing a curriculum rooted in information literacy.
