This is the typical response from faculty members and administrators who are asked how much undergraduate students should work at paying jobs while attending college. Available research supports this recommendation. Quantitative studies consistently show that retention rates are higher for students who work a modest number of hours per week (ten to fifteen) than they are for students who do not work at all or those who work more than fifteen hours per week. Research also shows increased academic success for students working on rather than off campus.

Unfortunately, this simple recommendation is no longer feasible or realistic for the typical undergraduate. Most college students are now not only employed but also working a substantial number of hours, a fact not widely understood or discussed by faculty members and policy makers. According to the National Center for Education Statistics, in 2007 nearly half (45 percent) of “traditional” undergraduates—that is, students between the ages of sixteen and twenty-four attending college full time—worked while enrolled. About 80 percent of traditional-age undergraduates attending college part time worked while enrolled. (See figures 1 and 2.) The share of full-time, traditional-age undergraduates working fewer than twenty hours per week has declined during the past decade (to about 15 percent in 2007), while the number working between twenty and thirty-four hours per week has increased (to about 21 percent in 2007). Today nearly one in ten (8 percent) full-time, traditional-age undergraduates is employed at least thirty-five hours per week. Contrary to the common belief that community college students are more likely to be employed than students at four-year institutions, the distribution of undergraduates by the number of hours worked is similar at public two-year, public four-year, and private four-year institutions,
