Croatian teaching profession has always emphasized the need to provide teachers a higher education degree, and to accent the importance of this profession for which they are responsible. In this paper, I will discuss about the history od the Petrinja Pedagogical Academy in the period between 1961 and 2004, the beginning of its founding, the organization of studies and the preparation of teachers who responded to one of the most noble professions. Establishment of the High Pedagogical School was the first step towards fulfilling the aspirations of the Croatian teaching profession for higher, more thorough and more versatile education, that would enable teachers to spread out the modern schooling in their living environments. One of the prominent professors of the Pedagogical Academy is definitely Stjepan Rupčić. Along the obligation as a musical culture professor and the head of Academy assembly, he also served as a dean from 1997 to 1999. Apart from work at the Pedagogical Academy in Petrinja, his influence is particularly evident in the city of Sisak, where professor Rupčić with his knowledge, working energy and popularity, has occupied a significant place in the history of Sisak musical culture and beyond. The aim of the paper was to cover the development of the Pedagogical Academy since its establishment and all the way to the academic year 2005/2006, when the Master's degree began to run as an integral undergraduate and graduate university study for five years lasting, and also to show the life and work of professor and musician Stjepan Rupčić, one of the most prominent members of the Pedagogical Academy.
