Bush's move to imposed national standards and testing on US schools was a good idea that exposed poor performance and lack of standards which then made it impossible to measure performance. It was defeated by conservatives and teacher's unions who then attacked state standards as well. The current secretary of Education under Trump has also fought standards since they interfere with religous teaching and the charter school movement which she supports. Charter schools have struggled to meet standards. Too bad the conseravative political climate and the constant resistance of the teacher's unions has beaten down measurement of educational performance.
