The Association of MBAs (AMBA) is a London-based international portfolio-accrediting organization with a focus on MBA programs at 365bet送彩金s worldwide. The Association is one of the three main global accreditation bodies in business education (see Triple Accreditation) and styles itself "the world's impartial authority on postgraduate management education". It differs from AACSB in the US and EQUIS in Brussels as it accredits a school's portfolio of postgraduate management programs but does not accredited undergraduate programs. AMBA is the most international of the three organizations, having accredited schools based in 52 countries, compared with 42 for AACSB and 38 for EQUIS.
