between september 1994 and july 2004, the "student council executive committee", "student council representative committee", "student council service team", "rosarian editorial board", "house captain liaison committee", "house executive committee" and "sports association" under the "co-curricular activities committee" were independent from the operations of "discipline team". since september 2004, a system called "an integration among student council, houses, sports association and discipline team" has been implemented. members from the four student council units, the elected captains from the six houses, and representatives from "sports association" are consistently regarded as "student leaders". they have to bear up with the prefect duties assigned by the "discipline team" while tackling with their leadership duties within the "co-curricular activities committee". moreover, all the "student leaders" have to elect several "head prefects" under a "one man, one vote" basis.
