The STMC Student Council’s main responsibility is to represent the student body with regard to school activities and programs. The student council is led by a board of senior students which includes: the Chancellor, Co-Chancellor, Treasurer, Clubs representative and Sports Representative. Council is also required to have a Grade level representative from each Grade in the school (8, 9, 10, 11 also). It is their duty to govern meetings and run activities, keeping in mind the interests of all students. Activities throughout the year include Grade 8 Orientation and Knighting, Pep Rallies, School Dances, Spirit Week and Greek Olympics, Grade 8-12 Mixer, and Christmas Spirit Week.
