Wishful thinking is not positive. In this political climate your wish as a hard demarcation will never happen. What I posted is a way to get there.
In my state there has been a flood of children who are nowusing On-line programs. Yes, they are offered by the state but they are run by privately-owned companies.
What is needed is **less** control from state agencies and school boards and more opportunity to choose private alternatives. Do this and the reforms you seek will naturally follow, as well.
Will we ever see complete separation of school and state? Likely not, but this should be the goal. If an arrow isn't pointed at the target it will never hit the bullseye.
