Co-op = relevant paid work experience

Waterloo's co-op program, the largest in North America, is an amazing way to explore potential careers, learn to interview for jobs, graduate with up to two years of valuable experience — and make money!

Sample co-op job titles

  • Full stack developer
  • Game programmer
  • DevOps engineer
  • Technical systems analyst
  • Research assistant
  • Software developer

Co-op work-study sequence

Starting in second year, you'll normally alternate between school and work every four months, integrating your classroom learning with real-world experience. You can return to the same employer for a couple of work terms to gain greater knowledge and responsibility or work for different employers to get a broad range of experience.

Your first work term will be after first year (May to August 2026).

Year September to December (Fall) January to April (Winter) May to August (Spring)
First Study Study Co-op
Second Study Co-op Study
Third Co-op Study Co-op
Fourth Study Co-op Study
Fifth Co-op Study -

or halfway through second year (which can be January to April 2027).

Year September to December (Fall) January to April (Winter) May to August (Spring)
First Study Study Off
Second Study Co-op Study
Third Co-op Study Co-op
Fourth Study Co-op Study
Fifth Co-op Co-op Study

There are options where you can have your first work term in the spring term after first year and your second work term after second year, or in the fall term halfway through your second year.
