WORLD EDUCATION INDICATORS 2005 EDUCATION TRENDS IN PERSPECTIVE This publication provides a range of comparable, cross-national education indicators for 19 middle-income non-OECD countries comprising over 50 per cent of the world population. In particular, it examines the extent to which countries were able to widen participation in higher levels of education between 1995 and 2002/3. Coverage includes data on educational attainment, education expectancy, enrolment rates of different age groups, age ranges of universal primary and secondary education, female participation, upper secondary enrolment patterns, entry rates into upper secondary and tertiary education, graduation rates, grade repetition, population and GDP, expenditure on education, teaching staff, class size, teachers' salaries, and expenditure per student. By examining the data from these countries and comparing it to that of OECD countries, this volume examines the factors which can generate growth in education in one country and constrain it in another. The countries participating in this study include: Argentina, Brazil, Chile, China, Egypt, India, Indonesia, Jamaica, Jordan, Malaysia, Paraguay, Peru, the Philippines, the Russian Federation, Sri Lanka, Thailand, Tunisia, Uruguay and Zimbabwe.

CENTRE FOR EDUCATIONAL RESEARCH AND INNOVATION Between 1961 and 2002, the Tunisian economy grew annually by 5 per cent while per capita income tripled by 2001. During this period, literacy levels and educational attainments increased signifi cantly, especially among women1. The country has reduced the overall incidence of poverty from 16 per cent in 1990 to 10 per cent in 2000, which refl ects progress towards the achievement of the MDG target of halvingpoverty by 2015.
