The article deals with education and the development of the school system in medieval Slovenia, which was very different that it is nowadays. Only a small percentage of the population was literate and had some connection with the school system, which on the other hand was not regulated, the »state« did not really care for it. There were no curricula or »knowledge catalogues«. Schooling was normally for the education of children within individual institutions and communities. Classes were adapted to these needs. For the Slovenian territory in the Middle Ages, it is typical to find first schools only after the end of the 12th Century, where one could absolve only the basic knowledge and obtain a rather modest education. Whoever desired more, for example lectures in septem artes liberales, law, medicine or theology, had to go abroad to study.
