This is an interesting article and an important topic. I think it shows that the global discourse is now getting a lot more mature and we are moving way beyond simplistic binary notions of public provision being axiomatically good and private provision clearly bad. The Bank/DFID project assumes that budget private schools exist because they meet a real need and the question for the state is how to support and regulate. I guess another question is whether the state should buy places in private schools for kids from disadvantaged backgrounds. If budget private schools are more effective educationally than government schools and cost no more per capita then surely the state should buy seats for poor kids.
