Based on what the School's response, I think normally people take Businessweek as the best ranking available. Then comes USNews. Since reasons we all know, rankings of FT is not that popular here in the States. As for WSJ, it is a good reflection of recruiters' perspective but seems that not that many people take it that seriously. Hope this may help.
thanks,uiber. You really release my puzzle. You know I noticed that Ohio State University (fisher) rank top 18 in US news but only among top 30-50 in business week, and university of washington (Olin) rank top 30 in business week but only around 47 in US news. Some schools' ranking is really quite different in different magazine.
Dear all: you can see the ranking in the chasedream, they all posted it, such as business week, FT and US news.
