The Estimates Committee of the Parliament, in its 47th Report (1967-68), recommended the setting up of a Service Selection Commission for conducting examinations for recruitment to lower categories of posts. Pursuant to this, and as an interim measure, an Examination Wing was initially added to the Secretariat Training School, subsequently renamed as the Institute of Secretariat Training and Management (ISTM).

The Administrative Reforms Commission (ARC), in its Report on Personnel Administration, drew attention to the fact that bulk of the staff of the Government at the Centre and in the States belonged to Class III and Class IV categories. Referring in particular to the identical nature of qualifications stipulated for entry into such posts in various offices, the Commission advocated pooling of the requirements of non-technical posts by different Departments and selection of personnel either by joint recruitment or through a recruitment board. It was in pursuance of this recommendation that the Government of India decided to constitute a Subordinate Services Commission under an Executive Resolution.

The Government of India, in the Department of Personnel and Administrative Reforms on 4th November, 1975 constituted a Commission called the Subordinate Services Commission which has subsequently been re-designated as Staff Selection Commission effective from the 26th September, 1977 to make recruitment to various Class III (now Group “C”) (non-technical) posts in the various Ministries/Departments of the Govt. of India and in Subordinate Offices.

The functions of the Staff Selection Commission have been enlarged from time to time and now it carries out the recruitment also to all Group “B” posts. The Staff Selection Commission is an attached office of the Department of Personnel and Training and comprises of Chairman, two Members and a Secretary-cum-Controller of Examinations who are appointed on such terms and conditions as may be prescribed by the Central Government from time to time. The Commission is provided such supporting staff as considered necessary by the Central Government.
