the economist intelligence unit, the business information arm of the economist group, gathered results from two internet questionnaires, one of business schools and one of their students and recent graduates, and used them to rate business schools located all over the world. information provided by the schools made up 80% of the ranking, with student and alumni responses accounting for only 20%. factors in the evaluation included faculty:student ratio, gmat scores of incoming students, student body diversity, foreign languages offered, percentage of graduates finding jobs within three months after graduation, percentage of graduates finding jobs through the school's career service, graduates' salaries and the comparison of pre-enrollment and post-graduation salaries, and student/alumni evaluations of the program, facilities, services, and alumni network. results were tabulated using a smoothing method incorporating the three previous years' results. the organization used strict data provision thresholds, with the result that some highly regarded schools were omitted from the list of 100 ranked schools.
