Over a Bridging Differences there's a good article on the dangers inherent in rating teachers by student test scores. This paragraph was striking:
I recently met with the principal of an elementary school in Brooklyn who hates the city's teacher data reports. She told me about an excellent teacher of a gifted class whose students started the year at the very top, near perfect. At the end of the year, their scores had dropped 5/100 of a percentage point. Given the margin of error on all tests, this is a meaningless difference, but the "drop" in the scores caused the teacher to be ranked in the bottom sixth percentile of all teachers.What is being done to teachers and schools right now is so wrong!
