The Trustees of Princeton University is a 40-member board responsible for managing Princeton University's $37.6 Billion endowment (2021), real estate, instructional programs, and admission.
The Trustees include at least 13 members elected by alumni classes, and the Governor of New Jersey and the President of the university as ex officio members.
The Trustees' mission and responsibilities stem from the original Charter of the college, written in 1746.
Notable recent policy decisions include implementing the residential college system, accepting coeducation, and increasing the size of the undergraduate student body.
This is similar to most of the oldest universities and colleges in the United States (including all of the Ivy League universities except for Cornell University), such as the President and Fellows of Harvard College and the Yale Corporation.
