School Vouchers...

The National Education Association (NEA) has an action-alert on a bill to re-introduce vouchers in the public school system in D.C. In the alert they state:

There is no solid evidence that vouchers improve student achievement. Vouchers would not expand the options available to parents in the District. Vouchers lack accountability. Vouchers do nothing to improve opportunities for children in D.C. public schools.

It would be interesting to see the results of a census on the public vs. private schools in the D.C. area to see a comparison between the two student demographics. Liberals typically refer to the haves and the have nots... wouldn't vouchers grant the free-market system of competition the power to level the playing field?
