Great effort has been invested in increasing STEM achievement among students, but feelings of low status among underrepresented or otherwise vulnerable students may be creating additional challenges. The present study assessed how perceptions of social status within the classroom--termed subjective social status--aligned with objective course performance and differed by sex, first-generation status, work status, and race/ethnicity among 713 students enrolled across three introductory statistics classes. Findings indicated that final exam score was moderately related to ratings of subjective social status, suggesting that factors besides objective course performance may influence classroom subjective social status. When asked to explain how they evaluated their standing in the course, students reported five main themes, including both academic achievement with respect to exam scores and their understanding of course content. When examining differences by status-based identities in subjective social status, we found that female and first-generation students had lower subjective social status compared to their male and continuing-generation peers, although results were less robust for first-generation status. Likewise, working students reported lower subjective social status relative to non-working students, despite showing no difference in final exam score. In contrast, although Asian/Asian American students outperformed Latine students, there were no differences in reports of subjective social status between Asian/Asian American, Latine, and white students. Taken together, results suggest that factors beyond course performance may relate to students' subjective social status, and subjective social status may contribute to disparities in academic performance, especially by sex and work status.
