Which is the exact opposite of what the DOE does.
Instead, the DOE has created Teacher Data Reports. If you haven't seen them, they are meant to tell teachers how they measure up against other teachers. The problem, of course, is that the data are meaningless, which pretty much means that any conclusions drawn from that data are horse puckey.
So how it works is this: The DOE gives a test to kids in one grade. The test is fatally flawed. Then, the DOE gives another fatally flawed test the following year. They create something called "value added", which shows how much a teacher helped a child progress had the tests been valid, which they were not. These reports will be used to determine tenure, and, coming soon to a school near you, they will be used to evaluate all teachers.
On the positive side, these reports are great for fertilizing crops. I don't think they'll end world hunger, though.
