This article analyses the means and boundaries of the professional autonomy that elementary school teachers enjoyed in the second half of the nineteenth century in the territory of modern-day Slovenia, previously part of the Austrian and Austro-Hungarian Empires. While their work had been regulated in great detail since the Elementary School Act of 1774, which laid down even the contents and methods of teaching to be employed, the subsequent 1869 Act stipulated that teachers could become members of school boards as a means of providing them with an opportunity to influence education policies. Teachers were required to attend teachers’ conferences where, among other things, participants discussed successful teaching methods and developed detailed curricula and lesson plans. Teachers expected these changes to bring them greater autonomy, as well as a say in school policies and greater public confidence in their professional authority. This paper contains an analysis of whether or not these expectations were met. Our analysis of school board and teachers’ conference reports published in the Slovenian educational press shows that in this period an important shift occurred in the way that teaching effectiveness was ensured and teachers’ work supervised. A system was put in place which at the same time facilitated and monitored the implementation of teachers’ ideas, and ensured and restricted their professional freedom. There was a significant change in authoritarian techniques, which quickly developed yet still facilitated the growth in teachers’ professional authority, as teachers gained power and space to fight the authorities for recognition of their status and ideas.
