What is CEI? CEI is the College Enhancement Internship program here at TCNJ where students are encouraged to intern for the college in offices all across campus! Here are just a few examples of offices that have hired students in the past: Alumni Affairs, Career Center, Student Affairs and many more! Student interns are given more responsibility and are assigned tasks pertaining to their department’s role at the college. Some of these tasks include, but are not limited to: website management, market positioning, event planning (varies from office to office).
