This week’s Common Core lawsuit sticks to some well-worn ground — arguing that the academic standards threaten state sovereignty. The lawsuit seeks to shut down Idaho’s version of the math and English language arts standards, established in 2013. But the plaintiffs’ 36-page lawsuit makes scant mention of the standards themselves. As I described in our story Tuesday, the fight hinges on the Smarter Balanced Assessment Consortium, or SBAC, the tests aligned to the Idaho Core Standards. The fight is over state sovereignty, of course, but also about money. The plaintiffs contend that the state is on the hook this year for $6 million for “an unconstitutional and wasteful expenditure of government resources”/Kevin Richert, Idaho Education News. More here.
