Reply #83: And there's the problem

[Recursion]

A school is also administrators, support staff, the community around it, the funding system that pays for it, the laws that create and regulate it, oh, and.... students, and their families.

I will grant you that on the whole educators have not come up with an evaluation system for themselves that works very well. And that there's overall too much focus on pedagogy and too little on subject mastery. And even that the idea of a 40-year career as a teacher may not be relevant to today's economic realities. But teachers are not the entirity of a school by any means.
