That's how we should be judged. Henderson will be able to see which teachers are bringing the most students along the fastest. Of course she'll also know which classrooms continue to struggle. Unlike most accountability systems, including Florida's, which focus on school performance, Sanders' system takes accountability down to the classroom level. That's the biggest concern, that Sanders' system could be used as a weapon against teachers.
Teaching is part art, part science.
I'm not as convinced as Bill Sanders is that his numbers do what he thinks they do. Sanders says he doesn't pretend to measure everything. He intends for his system to be just one of many tools for evaluating teachers. He wants it used to help identify what works and what doesn't. But it's the accountability piece that has politicians talking.
