The chapters in this book were prepared during the second phase of a study conducted by the Organisation for Economic Cooperation and Development to develop a set of International Indicators of Education Systems (INES). They were among the many studies presented at the General Assembly of the INES Project in Lugano (Switzerland), September 16-18, 1991. Taken together, these papers present what is currently known about the organization, development, measurement, and uses of international education indicators. Attention is given to the political contexts within which education indicators are used for informing policy-makers. The 18 chapters deal mainly with conceptual and analytical issues in the organization of education indicators. They are grouped thematically into four parts. Part I, "History and Definition of Indicators," presents a framework for the other contributions. Part II, "Development of Indicators," discusses issues in the development and implementation of different types of indicators. Part III, "Indicators of Outcomes of Education," is concerned with indicators of learning, student achievement, and other educational outcomes, such as labor market destinations. The five chapters in Part IV, "Interpreting Indicators for Policy," focus on the uses and abuses of reporting and interpreting international education indicators. Each chapter contains references.
