Education throughout the world has become increasingly diversified, moving from the traditional education of children to increasingly more education of adults outside formal school settings. This case study on Hungary is one of a series of studies that were conducted to map out the different components of the diversified educational field and analyze their relative importance; to identify the main factors, educational and societal, that are influencing the diversification process; and to examine the role of planning in that process. This study, the first of the series, gives special attention to the discussion of the conceptual issues involved in analyzing the diversification of the educational field. It also illustrates the urgent need to develop a good information base on the wide variety of educational activities taking place outside the formal school system. The book's six chapters describe the following: (1) the concept of educational diversification and its application to the Hungarian context; (2) a glance at Hungary; (3) the regular educational system in Hungary; (4) the first wave of diversification in Hungary--the creation of the system of supplementary education; (5) the second wave of diversification of education--the expansion of nonregular education; and (6) diversification of education and central policy and planning.
