"But besides all that, teaching is a profession that is charged with preparing and educating our youth for tomorrow. Obviously, teachers go into it knowing this, and often for that very reason. But in my eyes, that's quite a responsibility. There are plenty of better paying jobs out there with less vacation that, at the end of the day, don't make much of a difference."

If you ask me, that's all the more reason to increase pay and remove the near absolute job security. (Note: I haven't independently fact checked the job security so if its wrong please let me know). Given how important the job is, doesn't it make sense to align the incentives properly?

For the most part, when I hear people disagree with this, they tend to bring up specific problems with things like No Child Left Behind. Its hard to disagree that using bad techniques to measure teacher performance is a bad idea and I don't have a specific better solution, but I don't think that means we should stop trying.
