Yes. Studies show that students who work a limited number of hours actually do better in school than those who don't have a job. Fifteen hours a week is the suggested maximum. Earning more than $4,000 a year could put loans and grants in jeopardy.
No. Not if they will work more than 15 hours a week. An American Council on Education analysis of studies shows that those who work more are less likely to graduate in four years. Overall, their academic performance is likely to suffer.
If you are laid off or have increased costs, petition the school for more help. You could get a Parent PLUS loan to cover the gap.
