this is something I have been wondering about for a while now. In my school district (urban setting in Pennsylvania) student input amounts to exactly 0% of the final assessment for observed teachers. however, student performance, in the form of standardized test scores, amount a large percentage of a teachers final performance rating. Do any other states/countries take student input into consideration when evaluating teachers? if so, how does this look? I know from the peers I have spoken with that none of them have encountered student input being taken into consideration in the various rating systems at their districts. is there any research-based reason for this?
