MARKETPLACE –U.S. News & World Report started ranking colleges in 1983 and is now well-known for its many annual lists. It ranks high schools, law schools, business schools, you name it. But since November, more than two dozen law schools — many of them highly ranked — have announced they would no longer submit data to U.S. News, saying the rankings were profoundly flawed. This week, Harvard Medical School said it was withdrawing from the med school rankings. The dean wrote in an open letter that, essentially, education is too complicated a product to be ranked numerically.
