As to your last comment, I think that was slightly unfair. At no point did I suggest that there wasn't worth in one to one assistance. I was simply pointing out that under such a scheme the scope of the effect would not solve the problem at hand - not by a long shot. As I said, more power to all such people doing such work - it is good work, but we aren't going to get 50,000 kids out of a backwards education system that way. Each and every child counts - without a doubt, but systemic problems must be addressed systemically - everything else is a most welcome bonus.
