Tom Loveless, a nonresident senior fellow in Governance Studies, explains his latest research on measuring achievement of American students. “The bottom line here: the implementation of the common core has appeared to have very little impact on student achievement,” Loveless says. In this episode, he discusses whether the common core is failing our students, whether AP achievement is indicative of student success, and the role of principals as instructional leaders.
