MEASURING INPUTS IS NOT MEASURING OUTPUT. Joanne Jacobs has an item headed "Money doesn't buy excellence." It's about the dismal return on investment realized in the government schools. The Superintendent wishes to remind people that advocates of the government schools frequently object to vouchers on the grounds that to do so is to take money away from the government schools. The report Jacobs links to makes the point that the additional money spent on the government schools has produced ... nothing.
There is one consolation. Apparently Garrison Keillor could say, "and all the children are above average," and be telling the truth. "Wisconsin, Washington, Minnesota and Iowa had the top-performing K-12 schools. Mississippi, the District of Columbia, and Louisiana ranked at the bottom."
