This is not new, nor is it unexpected[1]. If you incentivize an outcome, people will try to get to that outcome. The problem with No Child Left Behind, is that they (foolishly) presumed that everyone would take the most difficult path to that outcome. If they wanted to stay with the testing metric framework, they would have been much better off with external testers.
