Is Working in College Worth It? How Hours on the Job Affect Postsecondary Outcomes

Abstract

Many students work during college to offset rising costs, but significant time on the job affects postsecondary outcomes. Analyzing the High School Longitudinal Study (N = 4,418), this article estimates the effects of hours worked on grades, credits earned, persistence, stopping out (i.e., unenrolling for 5 months before reenrolling), and dropping out. The polynomial regression analysis shows that after adjusting for background characteristics, prior academic achievement, institution types, and family obligations, “traditional” undergraduate students begin seeing deleterious effects at 20 hours, which becomes even more severe for those working 28+ hours (and the worst for Pell Grant recipients working long hours). While some work was good for students, on average, financial and family circumstances help explain the curvilinear relationships.
