Per the MCSG Constitution, MCSG is comprised of the Legislative Body (LB), divided into three parts: the Executive Board, the Cabinet, and the Class Representatives. The Executive Board consists of the President, the Vice-President, and the other Committee Chairs. The Cabinet consists of Issue-Based Liaisons. The Representative Committee is made up of four Class Representatives from each year. These elected members have full voting privileges.

The operations of the MCSG are supported by three non-elected Staff Members, who do not have voting rights.
