Triple accreditation or triple crown accreditation refers to the simultaneous accreditation of a business school by the three major international accreditation organizations: the Association to Advance Collegiate Schools of Business (AACSB) in the US, the Association of MBAs (AMBA) in the UK, and EFMD Quality Improvement System (EQUIS) in Belgium. [1] [2]
Each of the three institutions assesses a business school according to different criteria and scope:
Most business schools in the United States chose to only pursue AACSB accreditation. The structure of US business schools' MBA programmes often does not align with European standards. For example, AMBA accreditation criteria require all MBA students to have a minimum of three years of postgraduate work experience. This is a requirement that the vast majority of top US business schools cannot meet, as their MBA programmes also admit applicants with only a bachelor's degree and no work experience. [6]
A total of 141 business schools from around the world were triple-accredited as of 28 May 2025 [update] . [7]
