Students in the U.S. made significant progress in math and reading achievement on NAEP from 1990 until 2015, when the first major dip in achievement scores occurred,” reported U.S. News and World Report. Perhaps not coincidentally, 2015 is the year states were required by the Obama administration to have fully phased in Common Core.
Common Core is a set of national instruction and testing mandates implemented starting in 2010 without approval from nearly any legislative body and over waves of bipartisan citizen protests. President Obama, his Education Secretary Arne Duncan, former Florida Gov. Jeb Bush, Bill Gates, and myriad other self-described education reformers promised Common Core would do exactly the opposite of what has happened: improve U.S. student achievement. As Common Core was moving into schools, 69 percent of school principals said they also thought it would improve student achievement. All of these “experts” were wrong, wrong, wrong.
