Sandra Stotsky wrote a blog post on Pioneer Institute’s blog that deserves attention. You’ll get the gist in the opening paragraph:
Stanford University mathematics professor R. James Milgram included an informative e-mail in his packet of information for state legislators when he testified at a hearing on Common Core in Milledgeville, Georgia on September 24, 2014. The e-mail explains why presidents of many of the major mathematical organizations in the country endorsed Common Core’s standards in July 2013. The author of the e-mail seems to believe that the societies themselves would be unlikely to endorse Common Core’s standards, but that readers (i.e., the public) might be misled into thinking they had if they saw that the presidents had endorsed the standards. Consequently, the e-mail wants just the presidents’ signatures because they would “likely” be just as “effective.” The underlying assumption is that the members of these organizations would not be apt to learn what their presidents had done, much less know anything about the contents of Common Core’s mathematics standards.
People need to realize that these president’s signatures were personal endorsements, not endorsements from the organizations themselves.
