Three faculties, namely the Faculty of Letters (FS), the Faculty of Medicine (FK), and the Faculty of Veterinary Medicine and Animal Husbandry (FKHP), were formed at the beginning of the establishment of Udayana University.

The Udayana University Postgraduate Program was pioneered and established based on the increasingly urgent need to improve human resources (HR), especially educators, both within and outside Udayana University. The Udayana University Postgraduate Program was pioneered in 1992, beginning with the opening of the Linguistics Study Program (Prodi) Strata Two (Master) with the Decree of the Directorate General of Higher Education of the Ministry of Education and Culture of the Republic of Indonesia Number 431Dikti/Kep/1992 dated October 6, 1992. This Linguistics Study Program was the forerunner of the Postgraduate Program at Udayana University, which at that time was chaired by Prof. Dr. I Wayan Bawa. After the establishment of the Linguistics Master Program, a Linguistics Doctoral Program was proposed, which was also the first Doctoral program at Udayana University. The Linguistics Doctoral Program at Udayana University was established by the Decree of the Director General of Higher Education Number 300/Dikti/Kep/1998.
