Vouchers would be at the state level. The feds should have no place in education.
Here's the thing. In a free market, there are all kinds of niches that get filled. Where there's a demand, there will be a supplier. I'm suggesting that the hyper focus on performance through standardized testing would cease to dominate how we differentiate schools. Demand for schools that provide a diversity of educational opportunities would spring forth in place of our one size fits all approach. We desperately need innovation, creativity, and efficiency in the education market. Only competition can provide that.
When have such students been "dumped" into private schools...and I don't mean charters? Whether your assumption is true or not, the point is in a free market, those students would have the option of attending schools that specialize in meeting their needs. Or, maybe one of those low performing students happens to favor playing the piano. His attends the school that emphasizes the arts. Maybe another of the mediocre students decides college prep isn't for him so he attends a trade school, learns to become a killer chef...whatever! The point is, schools like that wouldn't bother comparing test scores, they'd sell their services like any other business. We need choice in education and the options that only a free market can provide.
Regardless of whether vouchers come from federal or state funds, if vouchers go to religious based schools, it will be a constitutional issue.
If public schools are abandoned in favor of private schools, then we will be dumping low achievers into private schools and tests scores in private schools will go down. Since they are only slightly better than public schools, there will be no improvement.
However, the most probably scenario, is that most low achievers which are the most expensive to educate will be left to the public school system sucked dry of funds by vouchers.
Disagree. A state redistributing money to a family for the purpose of paying for education does not constitute a law "...respecting an establishment of religion, or prohibiting the free exercise thereof...". In fact, it would seem that if the feds tried to restrict which school a family could spend their money on, THAT would be unconstitutional.

That makes no sense. If we had all private schools and as you stated, they're "better", how could there be no improvement? Again, the point is that with private education, we'd get diversity, innovation, and a focus on the customer (students and their families). We get none of this with monopolies, especially government monopolies. If you want higher test scores, only a free market can provide schools that focus on such things. Clearly, we're not getting that now.

Not logical. First, I'm suggesting government get out of the business of educating, which means there would be no public schools to get "sucked dry". Secondly, what makes you think the market wouldn't respond to the demands of low performing students? One can make profit from educating a low IQ person, can they not? Low performers are only more expensive to education in today's one size fits all monopolistic approach. That would not be true when schools began to specialize and focus on the demands of their customers.
