At some point the next few weeks, the results from the 2015 administration of the National Assessment of Educational Progress (NAEP) will be released. I can all but guarantee you that the results will be misused and abused in ways that scream misNAEPery. My warning in advance is twofold. First, do not misuse these results yourself. Second, do not share or promote the misuse of these results by others who happen to agree with your policy predilections. This warning applies of course to academics, but also to policy advocates and, perhaps most importantly of all, to education journalists.
much more of the NAEP scores here.
