Approximately 10% of college students participate in Greek-letter social organizations (fraternities and sororities), yet minimal research has been conducted on the career development of students in these groups. The purpose of this study was to examine Greek-life membership and students' vocational identity, career decision-making self-efficacy, and goal instability, three aspects of student career development. Participants included 205 students affiliated with fraternities and sororities and 231 nonaffiliated students. Two independent variables (group and gender) and three dependent variables (vocational identity, career decision-making self-efficacy, and goal instability) were explored, with GPA serving as a moderator variable. Limitations, implications, and directions for future research are addressed.
