Mo. Rev. Stat. § 174.060
Every two years during a regular session of the general assembly, the governor shall, by and with the advice and consent of the senate, appoint two regents for each college, and whenever a vacancy occurs in either of said boards by death, resignation, removal from the district or by operation of law or otherwise, the governor shall, in a like manner immediately appoint some competent person to fill such vacancy, and communicate his action thereon to the senate at the next session of the general assembly thereafter. The person so appointed shall hold his office subject to the confirmation of the senate, for the unexpired term; provided, that not more than three of said board, excluding the state commissioner of education, shall belong to the same political party. Of each board of regents, at least one member shall be a full-time student of the college over which the board has governance. The student regent, while attending the meetings of the board, shall receive his actual expenses, which shall be paid out of the university's ordinary revenue.
