This study investigated the differences between demographic, enrollment, academic, and self-directed learning characteristics of completers and noncompleters in online courses at one community college. The study also obtained students' self-reported reasons for not completing their coursework. No significant differences were found in the characteristics of age, gender, ethnicity, financial aid eligibility, grade point average, and total hours enrolled; significant differences were found in gender, academic readiness, and completers enrolled in more online courses than noncompleters.
