The University of Virginia's Darden School will enter a robust part-time MBA market in launching its new program in Washington, D.C. Last year, nearly 1,300 candidates applied to the existing five top part-time options which enrolled cohorts composed of 615 students. While Darden's program will bear the highest price tag, it also will be the highest ranked, likely landing in the top five of all part-time MBAs in forthcoming U.S. News rankings.
