MET published a study suggesting criteria for evaluating teachers. http://metproject.org/downloads/MET_Gathering_Feedback_Practioner_Brief.pdf 1. Choose an observation instrument that sets clear expectations 2. Require observers to demonstrate accuracy before they rate teacher practice 3. Require multiple observations prior to high-stakes decisions 4. Track system-level reliability by double-scoring some teachers with impartial observers 5. Combine observations with student achievement gains and student feedback 6. Regularly verify that teachers with stronger observation scores also have stronger student achievement gains on average In a statement Friday, American Federation of Teachers President Randi Weingarten, points out that the study fails to offer suggestions on how to use that evaluation process to improve teacher practice. Excuse me? The responsibility for improving solely rests on the teacher and no one else. Period. Once the teacher receives feedback then they must adjust. No one can make them.
