Delhi Subordinate Services Selection Board 
As per Article 320 of the Constitution of India, the examinations for recruitment to all posts and services of the Central Government are required to be conducted by the UPSC. However, the estimates Committee of Parliament in its 47th Report (1967-68) recommended setting up of a Service Selection Commission for taking over from the UPSC, examinations for recruitment to lower category of Class III posts. The Administrative Reforms Commission also in their Report on Personnel Administration made similar recommendations. Accordingly, it was decided by the Government of India to set up Subordinate Service Commission to conduct recruitment examinations to Class III categories, which constituted the bulk of the staff of the government at the Centre and in the States. After a careful consideration of the recommendations, the Government of India constituted the Subordinate Services Commission vide Department of Personnel and Administrative Reforms’ Resolution No.46/1/(S)/74-Estt. ‘B’ dated the 4th November, 1975. This Commission was subsequently re-christened as Staff Selection Commission (SSC) in September, 1977. It was empowered to make recruitment to Group ‘B’ and Group ‘C’ posts in various Ministries/Departments of the Government of India and its Subordinate/ attached Offices. However, the work relating to recruitment to Group A and Group B Gazetted posts remained with the UPSC.
Further, the work relating to recruitment of DASS and Stenographer cadre’s posts for Delhi Administration (now GNCT of Delhi) was assigned to SSC. The recruitment to Group C ex-cadre posts and Group D posts remained with the respective Heads of Departments of GNCT of Delhi. The major recruitment of ex-cadre posts were done by Education, Health & Family Welfare Departments. These departments had their own full fledged examination branches and Technical Recruitment Cells for the recruitment of teaching and medical posts. Delhi Police, MCD, NDMC, etc. had their own mechanism for recruitment and GNCT of Delhi had no role in it. Similarly, Autonomous Institutions, Undertakings, Boards and Bodies like DFC, DSCSC etc. of GNCT of Delhi were adopting their own procedures in the recruitment process.
But after enactment of Government of NCT Act, 1991 and to do away with the multiplicity of authorities in the recruitment process within the GNCT of Delhi, MCD, NDMC and its subordinate/ attached Offices, Autonomous Institutions, Undertakings, Boards etc. GNCT of Delhi had decided to set up an independent Delhi Subordinate Services Selection Board (DSSSB) for ensuring a free and fair recruitment process with transparency and accountability, for all these organizations, as an attached office to Services Department of GNCT of Delhi in 1997, vide Resolution No. F 3(7)93-5, III dated 04.10.1996. However, the work relating to recruitment to Group A and Group B Gazetted posts remained with the UPSC.
