All co-ops are required to complete a minimum of three tours. For engineering and technical co-ops a minimum of two tours must be completed during fall or spring semesters. For non-technical co-ops, a minimum of one tour must be completed during the fall or spring semester with the subsequent tours occuring during the summers. Three consecutive tours are not permitted.

All new co-ops must start in the fall or spring semesters . No new co-ops are hired to start work in the summer. Remember these scenarios are suggested; but, there are more possibilities for scheduling rotations. A final schedule needs to be negotiated among you, your school, and Johnson Space Center.
