This volume is structured as follows the first section goes right to the treatment of the broader aspects of the creation of an information system, with particular emphasis on issues related to the clear identification of purposes and users, as well as the central institutional aspects related to its operation. The second section stops at the specification of the information that such information systems generate or would generate. To do so, the need for information to be part of a coherent whole that gives order and meaning is emphasized. At the same time general reflections on what the quality of education is are presented and key themes (coverage and profiles tuition, efficiency, level of education of the population, literacy, income, conclusion, spending equity, learning achievements, educational content and teachers) are dealt with in greater detail and its conceptual and political considerations, as well as technical details on indicators that occur or could or should occur regularly are discussed. The third section discusses some aspects of special importance to the continuous improvement of information systems. This section addresses issues linked to consistency, handling omissions, estimates and projections issues, the importance of so-called metadata for the interpretation and use of information, the link with management, the use of census and sampling events, data aggregation and the use of micro data and educative mapping. Finally, it offers some reflections on non-formal education.
