There are many lists out there as included in the links below, with Stanford, HBS, University of Pennsylvania’s Wharton, Chicago Booth, Columbia, MIT Sloan, and Northwestern (Kellog) being among the top institutions on a yearly basis. Several other institutions including Duke (Fuqua), Yale, Dartmouth, UC Berkeley, NYU (Stern), and others offer extremely strong educational experiences with superb opportunities thereafter.
Different ranking lists have separate methodologies giving different weights to competitiveness, networking, compensation, and other factors for a program. However, it is important to go beyond simply pure rankings and consider the program fit that is right for you based on additional factors such as the curriculum offered, culture of the program, and placement of graduates thereafter by industry and geographically that match your particular interests best.
If you’re looking for some of these lists, here are the US News, Fortune, and Business Week rankings for comparison.
