The purpose of the quantitative ex post facto design of this study was to determine if, and to what extent, self-efficacy increases after the implementation of a pre-entry program for community college student athletes in Southern California. The self-efficacy theory provided the theoretical foundation to address the research questions in this study. The sample was composed of 21 community college student athletes in Southern California who completed a pre-entry program during the 2018/2019 and 2019/2020 academic years. The result of the paired samples t-test revealed the physiological states scores were significantly lower for the posttest (M-post = 26.24, SD = 1.660) than for the pretest (M-pre = 28.29, SD = 7.805), t(20) = 1.864, p = 0.038. There were nonstatistically significant main effects for overall self-efficacy, mastery experiences, vicarious learning, and social persuasion scores. These findings have implications for future research based on the study's strengths and weaknesses, and the results lay the groundwork for future research for improving the transition into community college for student athletes.
