I like the way PISA has pulled out certain states to make a point about achievement. Why Massachusetts, Connecticut, and Florida were selected, I do not know. In general, MA and CT did better than the national average, and FL did worse, which I could have predicted without the data.
When I try to argue in favor of the Common Core State Standards, I usually pull out two points: PISA scores unbecoming a world power and NAEP scores that indicate significant disparity among states in terms of student achievement. This report illustrates both.
