This study examines the impact that diversity courses (DC's), created to increase social awareness on college campuses, have on 553 students' interactions with faculty, critical thinking and social engagement. Conducted at a large, private tier one research institution, this study reviews a pre-college survey, post-college survey and student transcripts using a quantitative approach through factor analyses, reliabilities and multiple regressions. The findings suggest that the number of DC's students take impacts critical thinking and social engagement (beta = .089, p < .05). Participation in racial awareness workshops and community service also significantly impact critical thinking, social engagement and student-faculty interactions. These results reinforce the notion that diverse interactions are essential to the development of the individual as well as the collective whole.
