In India, In 1960s the concept if education was not given priority in people's mind and education to girls was given the least importance, Only the influential and better privileged sector of the society allowed their girls to go to the nearby schools where mostly co-education was available. The idea of boys and girls studying together was not entertained by the conservative rural society in those days. To guide and motivate the future generation, the great philanthropist Sri C.S.Ramachary, Chairman of Sitalakshmi Mills Limited, took it upon himself to start a school for girls. He realized that if the road leads to the goal, its length is immaterial. He christened the school as Sitalakshmi Girls School and started in June 1963 in a rented building.

The teachers canvassed and enrolled three hundred students in the first year and gradually over the years, the phenomenon of education took a deep root in all minds and the students rolled in for admission and Founder Chairman Sri C.S.Ramachary housed the school in its own sprawling three and half acres land with all the modern facilities. His idea were implemented into actions by late Sri M.S. Sivanth, of Chairman's family. He was one of the administrator and enabled smooth running of the school. The school has won many laurels and credits and everything is dedicated to the memory of the Founder. Mrs V.K.MEENAKSHI B.A.B.T was the first Headmistress of this Hr.Sec.School who served office from 1963-1979. The unique feature of the school is the Mid – day Meal that had been served by the Management to more than 150 economically backward children studying in the school with a elaborate menu of Rice, Sambar, Rasam, Curry, Curd and Pickle. Like wise free school uniform till now is offered by the Management to the poor students. The TamilNadu Government in appreciation of this Charity has given a citation to the school management.

Mrs.KAMALAM RAJENDRAN is the present Secretary of the school. There are about one thousand six hundred students studying in the school from VI to XII std both in English and Tamil Medium.
