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. Four Class Representatives are elected 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.
