	The rankings are based on a variety of factors such as standardized test scores of students, salary of recent graduates, survey results of graduates and/or recruiters, the specific schools that choose to participate in a market survey, the number of top companies recruiting at the school and a variety of attributes. The ratings vary significantly by method used to determine the success of each program. For instance, the "Forbes" and "Financial Times" results are based on long-term graduate career progress concerns, the "Bloomberg Businessweek" and "Economist" polls evaluate short-term experiences of the students with their program, "U.S. News & World Report" consider the recent experiences of recruiters with the program, and other rankings like the Aspen Institute "Beyond Grey Pinstripes" measure integration of sustainability material into business programs.
