NYT's Collins on testing and teacher evaluations (Wisdom!)

Gail Collins has a new op-ed that's partly about Florida politics and partly about the role of educators in our shared life.  Here's something important said very, very well:

Can I digress, people, and say that while it’s important to make teachers accountable, telling them their jobs could hinge on their students’ grades on one test is a terrible idea? The women and men who go into teaching tend, as a group, to be both extremely dedicated and extremely risk-averse. The stability of their profession is a very important part of its draw. You do not want to make this an anything-can-happen occupation, unless you are prepared to compensate them like hedge fund traders.
