Agreed.
People have a really bad problem of analyzing what's wrong with schools. Part of the reason why is that we always want to think in terms of us-versus-them. It's very difficult to keep in your head a system where intelligent people are all acting in good faith, yet the results are so poor. Much easier to buy into some kind of slogan.
Public education is a service, and like with any service, the people writing the check have certain expectations. With education, it's very simple: secondary education should provide the student with the ability to have a productive job and/or move on to higher education.
But there are a ton of confounding variables. Student populations are not the same. Facilities differ. We all know the spiel. This stuff is difficult! Good teachers require the ability to creatively match teaching style to students.
With difficult creative jobs, we know what works: as few rules as possible, clear acceptance criteria, and diverse people working in small groups with creative tension. This isn't a mystery.
Instead we've created overly-complex monstrosities of administration, consultants as far as the eye can see, an institutional, assembly-line metaphor for work, and stringent rules slathered on top. Then we add in teacher's unions and school boards. Finally, some smart ass came up with the idea "Just what are we doing, anyway? We need a test!"
I agree with the smart ass. We need a test. In fact, as a taxpayer without acceptance criteria I'm not paying for it. But tacking a test on top of the heaping pile of dog shit we currently have as an education system will not make it work. It'll just point out how bad it is. That's fine with me, but be prepared for a lot of fake "X raises questions" articles like this one as the establishment twists itself into pretzels trying to deny that it's the structure of the system itself that is at fault, not the tests.
So it's a tough situation. There are no good or bad guys, and that just makes it worse.
