The purpose of this study was to evaluate the impact of a mentoring program on self-efficacy beliefs. High-risk undergraduate students at Arizona State University majoring in Public Health and other closely-related fields represent this study's sample. Bandura's Self-Efficacy Theory guides this study's theoretical framework. This study used a mixed method, action research design. Participants took a pre-test that measures their self-efficacy and registered the barriers to their academic success; following that, they enrolled and participated in a mentoring program. Upon completion of the program, they completed a post-test to evaluate any changes to their perspectives. Non-parametric Wilcoxon signed-rank tests were applied to the surveys. Throughout the mentoring program, participants completed field notes and I completed a journal about our interactions. These, along with two focus group discussions, were analyzed using grounded theory in addition to the pre- and post-tests. The surveys found that the mentoring program impacted their self-efficacy in overcoming educational barriers the qualitative data showed a strong correlation between the intervention and perceived confidence. This included their perceived ability to perform difficult or unusual tasks, but also their ability to overcome barriers.
