AACSB International grants accreditation to business degree programmes worldwide. Found in 1916, AACSB is the longest serving global accrediting body for business schools that offer undergraduate, master and doctoral degrees in business and accounting. AACSB Accreditation is the hallmark of excellence in business education, and has been earned by less than five percent of the world's business programmes. Today, there are over 800 accredited business schools worldwide.

Lingnan University's Faculty of Business obtained the AACSB Accreditation for the first time in 2011 and its first extension in 2016. The Accreditation was extended for another five years after a recent round of Continuous Improvement Review by AACSB International, which reassured the Faculty's outstanding performance in teaching and learning, ongoing development, strategic management and innovations.
