LASAC was started in 1974 and became popular among the students of the Jesuit schools in Tamilnadu. “Let the society be raised” is the motto of this association. It provides leadership training and creates social awareness among the students. It instills in the minds of the students a spirit of self confidence, sacrifice, honesty and justice.
The Lasac students create green campus by planting trees and keep the campus clean from plastic items. They take new initiatives and help the teachers to maintain discipline in the school. Fr.S.Joseph Kennedy S.J is the director of LASAC in Tamilnadu.
