This publication contains a brief description of secondary education in Spain. It constitutes one part of a series entitled "Guide to Secondary Education in Europe," developed as part of a Council of Europe project. Chapter 1 presents a general overview of the Spanish education system, with a focus on secondary education. Chapter 2 describes education policy, funding, curricular organization, the role of the school as an organization and as a community, evaluation and assessment, school staff, and the influences of European innovations on education. The third chapter addresses issues of effectiveness and performance: student flows for 1970-90, dropout and repetition rates, admission to higher education, and employment opportunities for high school graduates. The greatest challenge that the Spanish education system faces is that of reform implementation. Appendices contain statistical data and a list of school legislation.
