In 1962 the Indian Parliament passed the 12th Amendment Act, 1962 to the Constitution of India, under which the Territory of Goa, Daman & Diu was included in the Schedule I of the Constitution of India (Constitution) and was declared as an Union Territory.

As an Union Territory, all the selections for Gazetted group "A" and "B" posts were made through the Union Public Service Commission (UPSC). All their service matters, such as promotions, confirmations, seniority, recruitment rules, disciplinary matters, etc. were controlled by the UPSC.

The reservation in favour of various categories like SC, ST, OBC, PH or CFF etc., are indicated as also the age limit. Only the candidates fulfilling all the essential requirements of the Recruitment Rules are considered to be eligible. Knowledge of Konkani is an essential qualification for direct recruitment in the State of Goa. Depending upon the number of candidates found eligible the candidates are short-listed by various methods viz. written tests and/or skill test and/or physical test and/or screening test and/or group discussions followed by an interview or only by an interview.

Under the Constitution (Fifty Sixth Amendment) Act, 1987 Goa was included in the Schedule I of the Constitution of India, as the 25th (twenty fifth) State of India.
