The data in the most recent Education at a Glance come from PISA 2000. Since 1992, the volume and range of statistics on education at international level has grown enormously. It is now possible to compare countries on a whole range of indicators from expenditure, class size, teachers, school organisation, use of computers, student achievement to participation in adult education. The demand for timely, accurate and relevant measures of educational development is to the fore more than ever nowadays recognising the fundamental role of education in our world.
