Thanks for pointing out the obvious. Listen, the problem with all of these "solutions" to education is that they are based on the FALSE assumption that one can effectively - and fairly - evaluate the effectiveness of a teacher. Test scores? No. Waaay too many variables to use norm-referenced tests. It depends on the students who enter your classroom. Student evaluations? Teaching becomes a popularity contest. Peer evalations? Same thing. Principal evaluation of classroom practices... maybe. Which is now it works now.
You simply can't do any outcome-based evaluation that's fair and effective. Private sector ("good business") approaches don't work. You can only evaluate what the teacher chooses to do in the classroom, not what happens as a result of those choices.
Teachers open the door; students must choose to enter. If you can find a away to evaluate (objectively, fairly) how teachers of different subjects with students of different abilities "open that door"... then I suppose you have something.
Until then, stop with the "keep the effective teachers, fire the bad ones" mentality, because even though there is definitely a range of teacher quality, as in any profession... figuring out who belongs where is a logicistal impossibility. AND expensive. But that's another story.
No offense but you are mistaken. There is what amounts to a religious belief among many (not all) teachers that teachers cannot be effectively evaluated and hired, promoted, bonused, fired, trained... based on such evaluations.
Guess what, every professional in the world feels the same way and would love to hide behind "You can't evaluate me because the variables are different for what I am working with versus what the guy down the hall is working with. Therefore, how dare you think of paying us differently or heaven-forbid fire one of us."
Guess what, performance evaluations happen all the time in less than perfect circumstances, with less than perfect measuring sticks, by less than perfect bosses. And guess what, unfair shit happens. But guess what else? Overall it works. Better performers advance, lower performers get lost. The overall quality improves.
"Oh, but teaching is different.". So is software engineering. So is providing legal services. So painting houses. So is recruiting employees. So is garbage collecting. So is designing marketing campaigns. So is...
Please at least consider the virtues of becoming an adult and joining the real world where everyone else lives. You may even find that you are a superior teacher and a decent system would reward you. It would certainly reward the kids.
