Co-op positions are career-related, paid work experiences for college credit. They enable you, as a student, to integrate classroom learning with practical professional experience in your field of study. Check with your educational institution to see if they have a Cooperative Education Program. The length of a co-op varies from 3 to 12 months and can occur at any time of the year. The co-op experience lends itself best to project-based work that requires more extensive training.
Summer internships are a great way to gain real-life experience, practice what you have learned in college, and get to know more about a company that you may be considering for full-time employment.
