Business school students are taught to think in terms of ROI — return on investment. So what's the ROI of business school? According to a survey of last year's Executive MBA grads at Temple's Fox School of Business, the answer is clear: On average, the students saw a 62 percent increase in salary at their jobs after completion of the program, and 41 percent of the class received a promotion. "Getting an MBA is absolutely worth it," says Christine Kiely, assistant dean at Fox. "The job market is tighter, and the more skills you have, the more valuable you become."
