ED released guidance for several components of the Stimulus today, including the Race to the Top Fund and the second round of the State Fiscal Stabilization Fund. Lots more on this to come.

Effective teacher means a teacher whose students achieve acceptable rates (e.g., at least one grade level in an academic year) of student growth (as defined in this notice). States may supplement this definition as they see fit so long as teacher effectiveness is judged, in significant measure, by student growth (as defined in this notice).
