Optional co-OP’s at RPI is technically correct, BUT the Arch Program at RPI with a “semester away” is a graduation requirement for all students. The Semester Away requirement can be met by an internship, a co-op, civic engagement, research, or a self-designed experience, BUT for the vast majority of students this requirement is met by an internship or co-op. The Arch program is very much part of the curriculum at RPI, including a required course reaching students the job search and acquisition skills needed to obtain the required internship, do-op, etc.
