Along with the changes in the perspective of a child and its development possibilities, a change in the education system of a preschool teacher appeared. Education of a preschool teacher is presented by a historical overview through phases of development which led to master's degree in early and preschool education. The preschool teacher's profession requests continuous professional development and lifelong training through different forms of such learning and advancement. As every system, the early and preschool education system has its foundation in legal frames and regulations which are presented in this thesis. The main goal of this thesis was to determine the connection between the education of preschool teachers and their satisfaction with work in preschool institutions. In order to process this research, a questionnaire with six questions aimed at general information regarding the examinees was used (sex, age, education degree, employment status, working experience and number of attended professional trainings in the last pedagogical year) and twelve questions regarding self-evaluation of satisfaction with work in preschool institutions. From the research's results it is possible to conclude that there is no significant difference between the satisfaction with work in preschool institutions given the education degree.
