We have one high school in Alexandria, T.C. Williams High School...In the Richmond metro area, 25 percent of high school students do not graduate on time with a regular diploma. This is an estimated 4,000 students from the Class of 2008. According to the Alliance for Excellent Education, if we reduced that number by 50 percent, the likely contributions these 2,000 students could make are significant: The combined earnings of this single class of new graduates would likely be as much as $29 million.
