I have a great deal of respect for Larry Cuban and his important work, but this blog post on Michelle Rhee reads like boilerplate applied to a situation that it doesn't fit.
For starters, when you actually read the new contract you'll see that Rhee didn't compromise a lot away, she basically got everything she wanted - including tenure reform. If there is a lesson in the contact timeline and resolution it's far less about compromise than about fortitude. Cuban says that the teachers got the raises they wanted. OK, sure. But Rhee wanted those, too!
The AFT's Randi Weingarten deserves a great deal of credit (which so far she hasn't gotten in the media in my view**) for signing a contract that effectively ends tenure and addresses layoffs in a respectful but cost-sustainable form, but the spin that this was a give and take deal evaporates when you actually read the document. It's precedent setting in some key ways.*
Second, I don't know where Cuban gets his 5 percent figure on the number of ineffective teachers in D.C.'s schools but while the percent can certainly be overstated in the public debate you're hard pressed to find anyone with firsthand experience in the D.C. schools or around them who does not peg that number higher. I was a charter trustee in D.C. for seven years and have spent a lot of time in both sector's of the city's public schools and would place that figure higher than 5 percent in a lot of the city's charter schools, too, by the way. This just isn't something the field does well yet.
