In 2010, a coalition of state governors and education experts developed the “Common Core,” a set of uniform guidelines for what American students should know and be able to do by each grade. When the federal government offered incentive grants as part of the stimulus, 45 states and the District of Columbia signed on to adopt the new standards. Now, many of those states are reconsidering their support. Critics say the standards are too rigid and confusing for students and teachers. And 11 states have pulled out of the Common Core testing, which is supposed to begin in 2015. Guest host Tom Gjelten and a panel of experts discuss renewed debate over Common Core standards and testing.
