The EFMD Quality Improvement System (EQUIS) is a business school accreditation organization based in Brussels, Belgium. It provides accreditation for higher education institutions of management and business administration and is run by the European Foundation for Management Development.^[1] It is considered as one of the triple accreditation.

EQUIS has accredited 210 institutions in 45 countries around the world.^[2] In 2022, Equis suspended all higher education institutions in Russia from its ranking.^[3]

EQUIS' directors in 2018 were Ulrich Hommel and David Asch.^[4] As of 2022, the EQUIS director is Alfons Sauquet.^[5] In the past 20 years of existence, the organization has accredited 189 institutions in 45 countries.^[2]

The accreditation is awarded to business schools based on general quality. The process also takes into account the business school's level of internationalization, which is not a strict requirement for accreditation by the other two major international accreditation bodies: AACSB and AMBA.^[6] As of 2014, all fully accredited EQUIS business schools applying for AACSB accreditation have succeeded, which has not been the case the other way.^[7]

EQUIS accreditation can be granted for three years (with annual progress reports on the areas of improvement required) or for five years (with a mid-term progress report on development objectives required).^[8]
