Duncan Plan: Remove AYP, Replace with "Demonstrated Success"

I'm told that pages 105-107 of the House-passed appropriations bill contains the language that the Duncan administration is seeking so that districts can receive i3 funding whether or not they have made AYP. 

I'm guessing that the highlighted language -- inserting "demonstrated success in significantly increasing student achievement" is the pertinent line.

I think it's a bad precedent that is only going to complicate things further down the line.  However, no one else seems to care about creating yet another way of picking and measuring schools.  So I must be wrong.
