Please read Sean Feeney's piece at the Washington Post about how badly APPR is designed and how it will ruin teachers careers and reputations.
Then send it around to everybody you know - especially people not in the education world.
Send it to the virulently pro-VAMers like Nick Kristof and the NY Times editorial page as well.
They won't care because they've convinced themselves the "science" of this is right.
But at least you can document to these people how much harm APPR is going to do so that when the harm comes to pass, we can say "We told you! We told you! Now do something about this!"
