Nonsense. You can't rate the countless dozens of things good teachers do with some phony metric. Any more than you can measure 'good' programming, 'good' science research, or any other human endeavor that requires creativity, tailoring responses to the situation, etc. "Objective" measures are a pipe-dream that's decades old. It's constantly thrown up as a 'solution', almost always by people with little or no education experience. Teachers have little control over the attitudes / motivations of students. You can bring a horse to water. Again, the evaluation of experienced professionals is worth something ... but good teaching is at least 50% art, and what works is a mystery that has to be solved one class at a time.
