The revolution of low cost private education is taking place across the developing world. In poor urban and peri-urban areas, private school children make up a majority of schoolchildren; even in rural areas, a substantial minority of parents is using private schools. Research has shown that children in low cost private schools outperform those in public government schools, even if they operate at a fraction of the cost. Importantly, low cost private schools are generally financially sustainable, and hence provide a scalable solution to the problem of providing education for all. In his talk, J. Tooley will examine this background revolution and follow educational entrepreneurs who are creating chains of low cost private schools. Such chains are attracting investment and creating radical innovations that have the potential to transform educational opportunities for the poor.
