Top Co-op Programs and Internships 2025

A co-op is usually a full-time, paid work term that lasts 4–8 months and is formally tied to your university. It often requires pausing school for a semester or two. Internships are typically 10–12 weeks during the summer and don’t need to be tied to your school. Co-ops usually offer deeper, more involved projects.

Check with your school’s career center or registrar. Some universities (like Northeastern, Waterloo, Drexel) have formal co-op programs where students alternate between school and work terms. If you're not sure, look up your major’s program page, co-op programs are usually listed clearly under degree requirements.

Usually no. Most co-op employers only consider candidates whose universities have formal co-op agreements. If your school isn’t part of one, apply to internships instead. Some co-ops may still accept you unofficially, but you’d need approval from the company and your university’s academic office.

Yes, but you’ll likely need CPT (Curricular Practical Training) authorization, which requires the co-op to be tied to your academic program. Rules vary by school and visa status. Some schools only allow CPT after two semesters, and the job must relate to your major. Always check with your school’s international student office before accepting.

If your school supports co-ops, they’re often worth it. You get more experience, better pay, and deeper project work than a summer internship. But they can delay graduation, so weigh the tradeoff. If you’re trying to land a competitive full-time job early, one strong co-op is often more valuable than multiple short internships.

Top co-op employers include IBM, Tesla, Google (for Waterloo students), Northrup Grumman, Johnson & Johnson, and many Canadian tech and pharma firms. These companies often have structured onboarding, mentorship, and return-offer pathways. Co-op-heavy companies also tend to give interns real production work, not just side projects.
