Cooperative education, internships, and summer programs allow engineering students to gain full-time work experience in their field through alternating periods of academic study and employment. A co-op requires at least two semesters and one summer of full-time work. An internship is a single full-time work period of at least one semester or one semester plus summer. Summer programs provide 10 weeks of full-time engineering work. These experiences provide benefits like increased career skills and salary potential while maintaining full-time student status without paying tuition.
