Work experience can be beneficial to high school students, especially when the work is regular and less than 20 hours/week. Previous studies have found that school-related work experience provides more learning opportunities with fewer negative consequences than jobs unrelated to school. This study analyzed responses of 22,183 seniors from 868 high schools who had been employed during the school year. In this study, contrary to previous studies, students with school-related jobs expected to get less education and were academically less able than those whose jobs were unrelated to school. Comparisons of students' self-reports of the quality of their jobs failed to confirm the hypothesis that school-related jobs were more advantageous than jobs unrelated to school. Black students were nearly twice as likely to report having school-related jobs as non-Hispanic white students. The difference in job quality may result from schools underinvesting in high-quality cooperative education, internships, and other forms of work-based learning.
