Here are the brand new 2015 federal National Assessment of Educational Progress (NAEP) tests scores sorted in order of the size of the White-Black Gap on 8th grade math. The color reflects whether the state went for Obama (blue) or Romney (red) in 2012.

A few comments:

• Although it’s often assumed that The Gap is due to racism, it tends to be bigger in blue Democratic states.
• Gentrifying Washington DC now has enough white children to get a white NAEP score. Sure enough, The Gap in very liberal Washington DC is bigger than in all the states, due to a very high white score in DC and a slightly below average black score.
• German-Americans and Nordic-Americans don’t seem to know how to deal with African-Americans. As I’ve often pointed out, the biggest Gap is in Wisconsin, but in this table Nebraska, Minnesota, and Pennsylvania have the next widest Gaps. (Any relationship between this and Merkel’s Boner is probably not coincidental.)
• The highest black scores are in Dept. of Defense schools (DODEA), followed by military intensive states like Arizona and Alaska and well-educated liberals states like New Jersey and Massachusetts that also have high white scores.
• The smallest Gap is in West Virginia, which has, by far, the lowest white scores.
