Case study research explored a formal mentoring program for new faculty within a cooperative Extension program at a land-grant university. This research focused on tenure-track and professional-track Extension faculty, who were paired with senior Extension faculty mentors in their first 3-5 years in the organization. Using the theoretical framework of the social cognitive theory (Bandura, 1977), the research focused on how a formal mentoring program influenced the mentees' experiences and the mentor's influence on the mentee's general description of self-efficacy. The research also studied how the mentor influenced the mentee's promotion pursuit experience. This research used the New General Self-Efficacy Scale (Chen et al., 2001) to measure participant's general self-efficacy. Results found that 21 out of 28 participants had a high self-efficacy score. To understand the mentees' perspective of their mentor's effectiveness, the research used the Mentor Evaluation Tool (Yukawa et al., 2020). Only 14 of the 27 participants perceived their mentors to be effective. Further review of the results provided areas for more exploration on these mentor-mentee relationships. Through in-depth interviews, a select group of participants shared how their mentors helped to build their self-efficacy through role modeling, collaboration, and support. This research not only looked at the mentor's influence on the mentee's self-efficacy but also discussed the personal relationships formed with their mentors, which contributed to the mentee's success, both personally and in the organization. However, not all participants had favorable outcomes with their mentoring experience. The understanding generated from this case study research contributed to forming a theoretical base for future research and guidance for mentoring programs within the national Cooperative Extension System. Implications for practice are shared on the research findings. This research not only looked at the mentor's influence on mentee's self-efficacy but also discussed specific aspects of the mentoring program.
