In 1992, the Graduate School of Applied and Professional Psychology (GSAPP) Alumni Organization was officially established with its own bylaws and officers. The alumni organization publishes a quarterly newsletter and works with the dean's office to update the annual alumni directory of all graduates. Other activities of the alumni organization include mentoring current students, participating on the Dean's Multicultural Advisory Council, providing professional networking opportunities, and fundraising for the GSAPP Alumni Fellowship and other activities that support the school. The GSAPP Alumni Organization is the newest member of the Rutgers Alumni Federation.

The sterling performance of GSAPP's alumni is reflected in their national leadership roles. Alumni include past presidents of the American Psychological Association, the Province of Ontario Psychological Association, and the National Association of School Psychologists and many officers and presidents of the New Jersey Psychological Association.
