In all the back and forth on NAEP results this week I was surprised that the free-and-reduced price lunch figures didn’t get more attention. In 2003 there were 40 percent of students in the 4th-grade sample eligible for free-and-reduced price lunch (a reasonable proxy for being low-income). In 2011 that figure was 49 percent. I’m inclined to the view that even accounting for this we should expect a great deal more from schools, but that’s not to say poverty doesn’t matter. And this trend matters.
