Does Pres. Bush Know What's In NCLB?

It's relatively rare you hear the President talking about NCLB for more than a moment, and usually sort of scary in a "what-is-he-going-to-say?" way when he does. At this recent event that the USDE has been determined everyone sees, Bush seems relatively well-prepared -- not that hard since he's only talking to editors -- but then lets loose with a bizarre comment that NCLB has "essentially ended social promotion in the early grades." What? How? Really? Where?
