I have read that in every study comparing those who won the lottery for entrance to a private school with those who lost, the private school students far exceed the progress of those who remained in the government schooled children.

However,....The NEA and education establishment elites have done highly biased studies ( highly massaged with means and socio-ecnomic ratings ) that show that there is no difference in achievement between government schools and voucher schools when averaged over all the participants. None of these studies has shown voucher schools ( on average) to be performing worse no matter how hard they tried to mash the data to fit their agenda.
