AMBA accredits postgraduate business programs at more than 260 business schools in more than 75 countries, with a philosophy focused on accreditation impact, employability and learning outcomes. This accreditation certifies that Olin’s MBA programs reflect changing trends and innovation in the postgraduate education sector.
