Tamil Nadu Public Service Commission (TNPSC) has the unique distinction of being the successor of the first provincial PSC in the form of the Madras Service Commission set up under the British colonial rule. Madras Service Commission came into being under an Act of the Madras legislature in 1929 in order to recruit qualified persons to the provincial and subordinate services. In 1936, the name was modified as "The Madras Public Service Commission".
The government recruitment body came to be known as Tamil Nadu Public Service Commission from 1970. The provisions relating to the Public Service Commissions are contained in Articles 315 to 323 of the Constitution of India, Chapter II of Part XIV.
