College athletes experience college in a way that is different than their non-athlete peers. Practices, travel time, study hall, and other athletic obligations place strenuous demands on the lives and time of college athletes. As a result, college athletes have less flexible time and are often unable to engage in educationally purposeful activities including high impact practices, that promote their personal growth and development. Using Astin’s Student Involvement Theory and Rendon’s Validation Theory as frameworks, this mixed methods study examined the impact that participating in a high-impact practice activity had on the personal growth and development of college athletes. To examine how personal growth and development was impacted by participation in a high impact practice activity, National Collegiate Athletic Association (NCAA) Division I college athletes at the University of California, Riverside (UC Riverside) participated in the Leadership for Social Change seminar. To measure personal growth and development, the participants completed the Personal Growth Initiative Scale - II (PGIS-II) as a pre- and post-seminar survey. A sample of participants was also interviewed after completing the seminar to further explain the survey results. The results of the study suggest that seminar participation led to personal growth and development for college athletes. Institutions and athletic departments should promote college athletes’ personal growth and development by incorporating high impact practices into the college athlete experience.
