Tamilnadu Public Service Commission (TNPSC) is a department under the Government of Tamilnadu created for recruitment of personnel for government service. The Commission was created by British India, under an Act of the Madras Legislature in 1929. Madras Presidency had the unique honour, of being the only province in India to establish the first Service Commission, which was named as Madras Service Commission.
The Madras Service Commission started with three Members, including the Chairman. After re-organisation of States in 1957, several Commissions were constituted. The Madras Service Commission became Madras Public Service Commission with headquarters at Madras in the year 1957. During 1970, when the name of the State was changed into Tamil Nadu, the Madras Public Service Commission automatically became the Tamil Nadu Public Service Commission (TNPSC).
In view of its important and impartial function, Public Service Commissions rightly find a place of pride in the Indian Constitution. Articles 16, 234, 315 to 323 deal with various functions and powers of the Public Service Commissions. The working of Tamil Nadu Public Service Commission is also regulated by Tamil Nadu Public Service Commission Regulation, 1954 and the TNPSC Rules of Procedure.
