The World Bank's first effort to spur educational investments in children was in Tunisia in 1962. At that time, 41 percent of the world's children aged 6-11 were not in school. 1 In SSA, only 25 percent of primary-aged children were in school, while enrollment rates in the Arab States (39 percent) and South Asia (44 percent) were only modestly better. Their parents were not in a position to produce the education in the home - only one-third of the adult population in low-income countries were literate and the average adult education level was 1.6 years. Even in middle-income countries, about 20 percent of the primary-aged children were not in school, and one-third of their parents were illiterate with an average education level of 2.8 years. Given the overwhelming evidence that literacy and schooling can improve health and economic outcomes, the World Bank's focus was on expanding the supply of available schools and qualified teachers.
