No Child Left Behind is one of the greatest blunders of the Bush administration.

From the Federal Patriot:

One of the greatest blunders of George W. Bush's compassionate conservative presidency is the No Child Left Behind Act of 2001, which was largely written by Teddy Kennedy. In five years, this bureaucratic boondoggle has done little to improve the quality of education in government schools, while loading an even heavier burden on taxpayers. A recent Harvard study concludes that the program will miss its goals for 2014 if trends continue. There has been negligible improvement to date in reading and math, and one of the Act's key components, closing the achievement gap between whites and minorities, has not done well either. As more and more schools fall into the "needing improvement" category, NCLB encounters more and more opposition. New Jersey is considering opting out, while there are legal challenges in Connecticut. The once bipartisan village success story is now an albatross around the President's—and taxpayers' —neck, though, conveniently, the key role Democrats such as Kennedy played in its creation is forgotten.
