Forty-five states have signed on to the Common Core and most are busy implementing the standards, albeit with some political resistance. How is it going? Admittedly, the Common Core era is only in the early stages—new tests and accountability systems based on the standards are a couple of years away—but states have had three or four years under the standards. Sufficient time has elapsed to offer an early progress report.
This year’s Brown Center Report on American Education progress report proceeds along two lines of inquiry.
First, a ranking system crafted by researchers at Michigan State University is employed to evaluate progress on NAEP from 2009–2013. The MSU experts found that states with math standards that were similar to the Common Core in 2009 scored higher on the eighth grade NAEP that year compared to states with standards dislike the Common Core. The current study examines data from the NAEP tests conducted in 2011 and 2013 and asks whether the same finding holds for subsequent changes in NAEP scores. Have the states with CCSS-like standards made greater gains on the eighth grade NAEP since 2009? It turns out they have not.
