The San Francisco NAACP is calling on city officials to declare a state of emergency over the the achievement gap between black and white students. Seventy-four percent of African American students failed to meet 2016-17 state assessment standards in at least one subject area, according to the district. In this hour, we'll talk with new San Francisco Superintendent Vincent Matthews about efforts to address the achievement gap. We’ll also hear about his plans for the district, and a proposed double-digit salary raise for the city’s teachers.
