Eric A. Hanushek, Paul E. Peterson and Ludger Woessmann, via a kind Chan Stroman-Roll email:

“Yet when compared to gains made by students in other countries, progress within the United States is middling, not stellar (see Figure 1). While 24 countries trail the U.S. rate of improvement, another 24 countries appear to be improving at a faster rate. Nor is U.S. progress sufficiently rapid to allow it to catch up with the leaders of the industrialized world.”
“Meanwhile, students in Wisconsin, Michigan, Minnesota, and Indiana were among those making the fewest average gains between 1992 and 2011. Once again, the larger political climate may have affected the progress on the ground. Unlike in the South, the reform movement has made little headway within midwestern states, at least until very recently. Many of the midwestern states had proud education histories symbolized by internationally acclaimed land-grant universities, which have become the pride of East Lansing, Michigan; Madison, Wisconsin; St. Paul, Minnesota; and Lafayette, Indiana. Satisfaction with past accomplishments may have dampened interest in the school reform agenda sweeping through southern, border, and some western states.”
