History
The school was founded by Mr. Pennathur Subramania Iyer. The emphasis of the Tamil Nadu state Government on Tamil being used as the medium of instruction was causing a fall in Tamil Nadu's share of employment in all-India and central services and in the national science and technology establishments. In 1973 P.S. Charities promoted the establishment of English medium schools. The P.S. Educational Society started, on 9 June 1976, P.S. Senior Secondary School, starting with standards I-VII from 1976. P.S.Senior Secondary School (affiliated with the CBSE), was started to help the public and very importantly, the employees of the central government and in the matter of the educational affairs of their children. The school is located in a spacious campus with well-equipped science laboratories and libraries. The school has a playground which spans over 10,000 square metres and a lot of importance is given to sports. The school also houses an art center, which focuses on identifying and nurturing talent. This decision was passed in the court case at the Madras High Court, labelled Dr. S. Anandalakshmy versus Government of India CBSE. Current principal
