Teacher Evals

Came across this today and thought I would pass it on since we have talked some about this in class. I can't imagine being evaluated on scores from students that I have never taught. Where is the common sense in all of this? If they want to use scores then okay-but don't make it the main (or even 50%) part of the evaluation. Take into consideration student and parent input, observations and other variables (leadership opportunities and such). I'd love to hear your thoughts.
