My guess is that reformers picked the low-hanging fruit of education reform in the early aughts. The introduction of standards and testing in the early days seems to have produced a bump in achievement. Over time however this effect may be fading.
Political Science 101 teaches that organized interests defeat diffuse interests 99 times out of a hundred, so the ability of states to employ a cat o’ nine tails and whip schools into improvement has limits. Dozens of decisions taken daily in the musty basements of State Departments of Education and obscure measures voted on by State Boards of Education can slowly but surely defang and/or subvert state accountability systems.
If there are two things that the organized employee interests of adults working in schools are expert at it is passive resistance and bureaucratic infighting. In my book, much of the reform crowd chose to fight their opponents on ground they did not choose wisely, and upon which they have little chance to prevail. Things fall apart, the center cannot hold.
Mike Petrilli recently and correctly imo noted that the 2017 NAEP would be a pretty definitive test on the efficacy of the Obama year projects- promoting Common Core and teacher evaluation, student discipline reform. Top down directives have a funny way of not working out, even backfiring. Let’s see what happens next.
