This master thesis deals with the national education system in Austria. The main focus within the context of this written presentation is on Otto Glöckel, who is considered as the key initiator of the education reform in the First Republic.In addition to the general history of the national education system, which is examined according to social, economic, and political aspects, the life and lifetime achievements of Glöckel are looked at more closely in this connection. The focus of this paper is on the so-called Glöckel-regulative and the related change processes such as for instance the constitution of the individual national education counselors in the respective states or the system of local, district, and state education boards. The subsequent section of this paper is devoted to the developmental course of this reform, which has been subject to all ruling factions and their educational policies ? from Austro-fascism to National Socialism. Another important part of this thesis is devoted to the reconstruction of the national education system after 1945 and its process of renewal, especially the foundation of adult education institutions (KEBÖ) in 1972 and the Education Promotion Act established in 1973. Moreover, a general description of their conceptual design, their expansion, and their present situation is provided. The concluding remarks constitute the conclusion of this research paper.
