Employment of part-time faculty members by community colleges has become an increasingly common approach to reducing institutional costs, which may have unintended consequences for student outcomes. This study examines the relationship between part-time faculty members and the associate's degree completion of community college students. The authors use hierarchical generalized linear modeling to analyze student- and institution-level data from the California community college system to determine how student exposure to part-time faculty members affected the likelihood of earning an associate's degree. Findings indicate that students experienced a significant yet modest negative effect from exposure to part-time faculty members on the probability of completing an associate's degree.
