In a “ranking of ranking” type index, Poets and Quants have ranked Business Schools both in the US and abroad.
I think what makes the ranking meaningful is because it aggregates all the metrics that each of the different rankings consider. And the results are not really surprising (Harvard, Stanford lead the pack; my alma mater Columbia Business School lands at 5).
Anyways, here is the methodology that Poets and Quants use. Click here for the rankings.
Methodology: Schools on each of the five major rankings were scored from a high of 100 to a low of 1, the numerical rank of the 100th school on any one list. Then, those sums were brought together, weighting the BusinessWeek ranking 30%, the Forbes ranking 25%, the U.S. News & World Report rankings 20%, the Financial Times rankings 15%, and The Economist ranking 10%. These differing weights reflect the authority and credibility we believe each of these rankings have in the business school universe. For a deeper explanation of the strengths and weaknesses of each system, see how we think the most influential rankings stack up against each other in “Turning the Tables: Ranking the MBA Rankings.”
