EDUCATING THE POORESTHоw cаn we get the wоrld’s pоorest children into school? This is а difficult question with no eаsy answer. In 1999 the UN adopted a set of goals called ‘Education for All’, but in many countries there has been little progress towards these aims.In Nigeria, for instance, the number of children not going to school has hardly changed since then. It is estimated that worldwide, about 72 million children never attend school, 45 per cent of whom are in sub-Saharan Africa. Even when schools and teachers are provided, there’s no guarantee that teaching is being done: World Bank research in India shows that a quarter of teachers don’t attend school on anyone day.Several proposals have been made to improve matters. A British academic, Professor Tooley, argues that low-cost private schools are more effective in delivering education to the poor since parental pressure maintains good standards. State schools could also relate pay to performance: research by Muralihadan and Sundararaman in India found that this improved students’ test performance far more significantly than spending the same money on teaching materials.
