I just noticed that four of the five contenders for this year's Broad Prize for Urban Education are from either Texas or Florida. While the award goes to school districts, I think this is another indication that state context matters. And what do these two have in common, besides a "former Governor Bush"? First, a longstanding testing-and-accountability system. Second, a robust alternative certification sector. And third, weaker teachers unions than you'll find in most locales. These things matter.
