Understanding the concerns high school students have about college presents opportunities to address college-bound students' needs before they arrive on campus, potentially increasing enrollment and retention. In this study, we investigated the academic, campus, social, and personal concerns of college-bound high school students and how these concerns differed for diverse groups of students (by gender, race/ethnicity, first-generation, and income level). Results showed that academic and personal concerns were highest across all demographic groups. Female students were more concerned about campus issues than social factors; the opposite was true for male students. Students from lower-income families or minority groups had greater concerns than their peers. Recommendations for mitigating some of these concerns are provided.
