Undecided students who self-identify as uncertain of their academic path represent a unique population to support from an academic advising perspective. In a sample of 257,813 students who entered 243 four-year institutions nationally, this study examined the relationship between students who selected undecided as their intended college major and individual student characteristics. Results indicate a primary predictor of undecidedness is student acknowledgment of indecisiveness about their choice of major or career; however, undecidedness also is related to interpersonal and contextual characteristics previously unexamined. Advisors should assess students' level of major and career certainty, concerns about financing college, and aspects of students' identities that were predictive of undecidedness.
