(CNN) – Chicago's Urban Prep charter school launched with a mission: to get more African-American teens back in school and send them on to college. The school's founder says over half of the black males in the city's public schools drop out before finishing high school, and only one in 40 will get a college degree. But now, every single member of Urban Prep's first-ever graduating class has been admitted to a four-year college or university. The school's founder and CEO, Tim King, joined us on Tuesday's American Morning to tell us how they did it, along with one member of this year's graduating class, Cameron Barnes.
