When it comes to hiring undergraduate business students, employers look for a few things. Good grades are important, as is campus involvement, preferably with a leadership position or two. But the most valuable section on the résumé is work experience, which, for a college senior, most often comes in the form of an internship or co-op.

When Bloomberg Businessweek started ranking undergraduate business programs, in 2006, only 55 percent of students reported having at least one business-related internship. For the Class of 2013, that number has jumped to 73 percent, and at many schools, it’s much higher. Today we look at the 10 undergraduate business programs where the most students boast that highly valuable internship experience, led by Northeastern University’s D’Amore-McKim School of Business.

For more than a century, Northeastern has offered a cooperative experience, or co-op, program in which students get at least a year of relevant work experience before they graduate, broken up into two or three six-month cycles. The business school works with more than 600 companies, including General Electric (GE), PricewaterhouseCoopers, Staples (SPLS), and Ernst & Young, to make sure each student who wants a co-op gets one. Co-op cycles run from January to June and July to December. Most students graduate with at least two.
