I wrote a bit about this yesterday, but there really is something fishy about the new NAEP test in Economics. Kevin Drum notes for example that looking at three different NAEP subject tests together you get the absurd result that "35% are proficient in reading and 23% are proficient in math, but 42% are alleged to be proficient in economics." One of the sample questions, meanwhile, seems to confuse the idea of a "risk" with the idea of a "cost."
