Professor of Public Policy, U.C. Berkeley, David Kirp spoke to Bill about his new book "The College Dropout Scandal." Bill and David discuss the scale of the problem and shows that it's fixable - -we already have the tools to boost graduation rates and shrink the achievement gap. Many college administrators know what has to be done, but many of them are not doing the job - -the dropout rate hasn't decreased for decades. It's not elite schools like Harvard or Williams who are setting the example, but places like City University of New York and Long Beach State. Plus, David hope to shine a light on an underappreciated problem in colleges today and prompt colleges to make student success a top priority and push more students across the finish line, keeping their hopes of achieving the American Dream alive.
