Statisticly Speaking, Are Black male teenagers GRADUATING?

Well, ten years ago the national rate for minority children making it through grade school to graduting High School was as follows. 50% for black s, 51% for Native Americans, and 53% for Hispanics respectively. This information was gathered and documented by the Civil Rights Project at Harvard (CRP). Also involved the Urban Institute, Advocate for Children in NY, and Results for America. Here we are ten years later, and has anyhting improved for us in DC? Well, as of 2009 the on time graduting rate was well below 50%, a shocking 48%: MD & VA rates didn't improve from 1990's rates, but werwe still much higher than DC. DC the nations capitol, why are we still struggling with this in 20011?
