We believe it can. In fact, within a few days we'll publish a white paper explaining more about how we think about teacher pay (and pay for everyone really) and how to implement it for your school. So, be on the look out ad we put on the finishing touches this week.
It's too big to post here, but we'll give you an email address where you can get it. Please request it, read it, and let us know what you think. We want feedback as we seek to create the best possible method of rewarding and retaining excellent teachers.
