The Ten-Cent Solution

"Cheap private schools are educating poor children across the developing world—but without much encouragement from the international aid establishment."
Clive Crook in The Atlantic writes about the research and experiences of James Tooley covered earlier.He poses the question, why have we not heard about this idea? :

This is not because his work is dull or unimportant. His findings are surprising, and they bear directly and profoundly on the relief of extreme poverty all over the world. (Name me a more important issue than that.) The reason you haven’t heard of James Tooley is that his work is something of an embarrassment to the official aid and development industry. He has demonstrated something that many development professionals would rather not know—and would prefer that you not know, either...On the whole, dime-a-day for-profit schools are doing a better job of teaching the poorest children than the far more expensive state schools. In many localities, private schools operate alongside a free, government-run alternative. Many parents, poor as they may be, have chosen to reject it and to pay perhaps a tenth of their meager incomes to educate their children privately. They would hardly do that unless they expected better results.

Better results are what they get. After comparing test scores for literacy and basic math, Tooley has shown that pupils in private schools do better than their state-school equivalents—at between a half and a quarter of the per-pupil teacher cost. In some places, such as Gansu, China, the researchers found that private schools serving the poor had worse facilities than comparable state schools; in Hyderabad, they were better equipped (with blackboards, desks, toilets, drinking water, and so on). Regardless, the tests so far show that private-school students do better across the board.
