Whoa baby! Are those some wacky value-added metrics. The pretests are based on averaging across math, science, and reading. What in the world does that measure? Post tests are based on the highest eight scores on a battery of tests - so, individual post test scores aren't even based on the same tests.
I guess some of the state growth models being suggested in the U.S. don't look that bad.
