The role of the College's trustees is, and always has been, to assure the "great and lasting good" of Grinnell College. Through their commitment to institutional stewardship, bold financial investments, and prudent management, the trustees have allowed Grinnell to develop its special character as an institution that combines academic quality with a service mission. The College's rich history and strong endowment are a testament to its trustees' decisions, financial acumen, dedication, and faithful service.

The Board consists of not less than sixteen and not more than 32 regular members, at least one-quarter (1/4) of whom are alumni or alumnae of the College. All trustees are elected by the Board. Each trustee serves a term of four years and is eligible for re-election for three consecutive, full terms. A trustee who has served three full, consecutive terms may not be re-elected unless at least one year has elapsed since the end of the person's most recent term.

The officers of the corporation consist of a Chair, the President of the College, one or more Vice-Chairs, the Secretary, and the Treasurer of the College. The Chair is the presiding officer of the Board of Trustees and is elected by the Board; he or she holds office for a term of two years and may be re-elected for two terms.

The Grinnell College Board of Trustees meets formally three times during the academic year in the winter, spring and fall. Special meetings of the Board may be called at any time.
