The Milken Family Foundation has created a new (electronic) newsletter tied to its pathbreaking Teacher Advancement Program, but also addressing broader issues of teacher quality. The inaugural issue contains an interesting overview of teacher "pay for performance": where it's been tried, what's happened, what can be learned. You can inspect it at www.mff.org/tap/tap.taf or subscribe by emailing [email protected] and asking to be put on the list.
