Forbes published its 2015 rankings for MBA programs in September 2015. Stanford GSB and Harvard Business School are in the first and second positions respectively. The ranking is based on the return on investment achieved by the graduates from the class of 2010.
The rankings methodology compares 2010 graduates’ work compensation in the first five years out of b-school to their cost of attending business school (tuition, fees, and two years of foregone salaries).
