Has the Common Core failed?

In just three years, 45 states adopted the Common Core State Standards. By that metric alone, one might argue that the Common Core was a huge success. But on this episode of The Report Card with Nat Malkus, Tom Loveless and Morgan Polikoff argue that the Common Core has failed to move the needle on student learning and discuss the potential of standards-based reform going forward. Read Tom and Morgan's recently released books on the Common Core and content standards:Between the State and the Schoolhouse: Understanding the Failure of Common Core (Loveless, Harvard Education Press, 2021)Beyond Standards: The Fragmentation of Education Governance and the Promise of Curriculum Reform (Polikoff, Harvard Education Press, 2021)
