At the beginning, the contribution of the Minister for National Education, George Papandreou, was very important for the School, which consisted of two departments, the Political-Historical and the Social-Economical, while the studies were planned for six semesters. In 1936 the School was recognised as "Public Utility of Higher Education" and in 1937 it was turned into "Legal Person of Public law". In 1951 the two departments were renamed to Department of Political Science and Department of Public Administration respectively, while the course of studies expanded to eight semesters in 1963.
