I can tell you right now why they do things this way: it reduces the bargaining power of the teacher to demand a higher salary. If you want to negotiate a salary with someone, the last thing you want is for them to be able to claim to be unique- if their lesson plan is prescribed, the test are prescribed, etc, then all you really need is to hire someone who can follow instructions, and if that person doesn't follow their instructions they can be easily replaced, on the cheap. Turning people into machines is what we Americans do best.
