The quest for quality has been the major concern of the entire human civilization. What is quality? Whenever quality in education is discussed it may be important to reflect on, what is understood by the term quality. Many educators, researchers and politicians have tried to define this term and a number of different definitions can be found in the literature. One almost classical definition is the way in which Coombs (1985) described quality in his book “The World Crises in Education: The View from the Eighties”: “Qualitative dimensions means much more than the quality of education as customarily defined and judged by student learning achievements, in terms of traditional curriculum and standards. Quality pertains to the relevance of what is taught and learned - to how well it fits the present and future needs of the particular learners. It also refers to significant changes in the educational system itself, in the cultural and political environment.” (Coombs, 1985, p. 105)
