Alliance’s reports on graduation rates featured in Virginia Daily PressJust two years ago, Virginia posted a 2011-12 graduation of rate of 83 percent, about 3 percent higher than a record national graduation rate. The D.C.-based, nonprofit Alliance for Excellent Education maintains that Virginia's reduction in dropout rates indicates a potential increase in real-lifetime earnings of almost $900 million. That's an encouraging estimate, but there are other numbers shouting that the situation is dire. Just this past week, reports of statewide SOL results revealed modest gains in math, while reading and writing pass rates dipped. Officials estimate that as many as 600 of the commonwealth's 1,800 schools could lack accreditation as a result of SOL test results.
