Jason Stanford, a first-rate journalist in a texas, looks for the lessons in the meteoric rise and astonishing descent of Michelle Rhee.

The major lesson, he says, is not so much about her as about the deep flaws in the test-and-punish philosophy she embodied. Putting the squeeze on subordinates to raise test scores leads to all sorts of negative consequences, but not to good education.

The flaw is inherent in No Child Left Behind and Race to the Top.

Until we get a better vision of education, there will be more Beverly Halls and Michelle Rhees.
