Morgan Adle writes: “U.S. News & World Report publishes rankings of graduate schools and programs, including the Best Library and Information Studies Programs. Graduate programs often highlight their ranking on their websites or in their promotional materials, and prospective students frequently rely on them when choosing programs to apply to. But what do the rankings really mean and how are they calculated?” While six graduate degree programs, including business and medicine, are ranked using “statistical data and expert assessment data,” other programs including library and information science are ranked using peer assessment only.
