In a study from the early part of this century, Learning and Earning: Working in College by Orszag and others, it was found that students who work a reasonable number of hours per week while enrolled in college, say 8 to 12 hours, actually perform better academically than students who do not work. A student working 20 or more hours per week and enrolled for a full-time course load may be hurt academically, but an increasing number of students are doing just that to address the issue of rising college costs.
