From a Washington Post story by Nick Anderson and Susan Svrluga headlined “Columbia University ends cooperation with U.S. News college rankings”:

Columbia University said it will not submit data to the U.S. News & World Report ranking of undergraduate colleges and universities, posing the latest challenge to a publication known for listings that shape the hierarchy of higher education.

The announcement comes about nine months after the Ivy League school in New York disclosed that it had misstated key points about class size and faculty credentials as it climbed to the second-ranked position on a U.S. News list of national universities. Amid the embarrassment, the university had halted its data submission to U.S. News while it reviewed the matter. It sank last fall to 18th place.
