Mentoring programs have proven highly successful in many industries, and therefore there is an increasing demand for such programs in other fields. Therefore, this study proposed to design and operate an LIS student-librarian mentoring program. To accomplish this, mentees were selected from the LIS students at K University, and mentors were selected by mentees from a pool of LIS workers. The mentoring program was then operated for three months, and all participants were surveyed before and after the program. As a result, first, it was revealed that the librarian mentoring program allowed mentees to enhance their understanding of the practical field, and help them to set career paths and goals. Second, participants insisted that six months is a more appropriate mentoring period, 2-3 hours per meeting is proper as a mentoring time, and considered that the information for mentors and mentees must be provided to each other before mentoring. Third, the intention to rejoin a mentoring program in the future was very high in both groups, but they insisted that the financial support, locational support, and providing sufficient information about mentoring program must be considered.
