Mike and Checker, who were at the Excellence in Education summit in Orlando yesterday, may have more to say about this. Apparently New York City Schools Chancellor Joel Klein, speaking at the summit, discussed the possibility of his seeking the power to certify principals and teachers, currently the province of ed schools alone. Call him reckless or brash or whatever you will, but Klein has done more than any other district leader in recent memory to bust the monopoly that has stifled change and innovation in public schooling.
