text_A: Rice University is chartered as a non-profit organization and is governed by a privately appointed board of trustees. The board consists of a maximum of 25 voting members who serve four-year terms. The trustees serve in an unpaid position and a simple majority of trustees must reside in Texas, including at least four within the greater Houston area. The board of trustees delegates its power by appointing a president to serve as the chief executive of the university. David W. Leebron was appointed president in 2004 and succeeded Malcolm Gillis who served since 1993. The provost, six vice presidents, and other university officials report to the president. The president is advised by a University Council composed of the provost, eight members of the Faculty Council, two staff members, one graduate student, and two undergraduate students. The president presides over a Faculty Council which has the authority to alter curricular requirements, establish new degree programs, and approve candidates for degrees.
