Business education at AUB started in 1900 but remained under the auspices of the Faculty of Arts and Sciences until September 2000 when the University established an independent school of business as its sixth faculty. In 2003, it was named in honor of the late Suliman S. Olayan, international Saudi businessman and AUB trustee. Today, the Suliman S. Olayan School of Business provides rigorous undergraduate and graduate business education with uniquely crafted curricula that are balanced between theoretical and practical approaches. OSB graduates approximately 320 students from its undergraduate program and 70 students from its graduate programs every year. It has grown enormously in recent years and now has a number of established knowledge centers and initiatives that encourage teaching and engagement between OSB and the private and public sectors.
OSB attained its initial AACSB (Association to Advance Collegiate Schools of Business) accreditation in 2009 and was re-accredited in 2014. AACSB is a US-based international accrediting organization considered as the benchmark of quality business education worldwide.
