Harvard Business School, Yale School of Management, Boler School of Business... what's the commonality?
...AACSB Accreditation

As the largest, oldest, and most prestigious accrediting agency, The Association to Advance Collegiate Schools of Business (AACSB) offers the "gold standard" certification. AACSB confers approximately 25% of business schools worldwide, but only 11% hold accreditation at both the undergraduate and graduate levels plus the independent Accountancy accreditation. The Boler School of Business maintains this dual accreditation, placing the school in the top 11% of the business programs in the world.
 
AACSB Accreditation ensures that students receive education from certified experts and that employers invest in professionals with knowledge that adds value to an organization in a meaningful way.
