I don't think there will be many private schools that will take a student with the state money. Once they do that, the state can start controlling what the private schools teach, etc. I think this will end up in the supreme court and hopefully be declared unconstitutional. I've been retired from public school since the 17 - 18 school year and remember that just about every legislative session the UNFUNDED mandates that would come down from the state. They have been trying to kill public education in Texas for at least the past 25 years, contrary to the Texas Constitution. It seems like more of the Ross Perot syndrome where you blame the public schools for the failure of your own child.
Sorry for the ramble.
