The University Grants Commission (UGC) came into existence on 28th December, 1953 and became a statutory Organization of the Government of India by an Act of Parliament in 1956, for the coordination,determination and maintenance of standards of teaching, examination and research in university education.
As RTI application to University Grants Commission (UGC) is filed online on the government portal, the wait time for getting a response may be expected to be a little less than usual.
