Trinity College’s business school has been granted world-class status after getting accredited by a top educational body. Trinity Business School announced on Tuesday that it has obtained the stamp of approval from the US-based Association to Advance Collegiate Schools of Business (AACSB) . It already enjoys accreditation by the Association of MBAs (AMBA) in London and the European EQUIS body. Only 100 business schools in the world have accreditation from all three bodies. “It’s a bit of a game changer for Ireland,” said Professor Andrew Burke, Dean of the school. “It’s key for businesses based here, in terms of having a top-quality graduate market to draw upon.”
