In the year 1923, the Indian Government established a Public Service Commission to examine the salary structure of the Indian Civil Service and the possibility of transferring some of the duties to provincial services.
The Commission also addressed the rate of Indianisation of the Indian Civil Service and the Indian Police.

It was left largely to the discretion of provincial governments to recruit and exercise control over their services, as deemed proper.
Madras Presidency was the first province in India to establish their own service commission when the Madras Service Commission was established under an Act of the Madras Legislature in 1929.

The Madras Service Commission became the Madras Public Service Commission with headquarters at Madras in the year 1957.
During 1970, when the name of the State was changed to Tamil Nadu, the Madras Public Service Commission was renamed as the Tamil Nadu Public Service Commission (TNPSC).
