In 2014, the Brennan School of Business earned accreditation from the Association to Advance Collegiate Schools of Business (AACSB) -- the largest and most prestigious accrediting body of business schools. Of the world's more than 13,000 business programs, less than 5 percent have been accredited by AACSB, which conducts a rigorous evaluation of teaching, research, curricula development and student learning.

AACSB accreditation of a school is important to students because it signals a quality learning environment, certified faculty and researchers, and a comprehensive business curriculum that can withstand strict scrutiny. Because of this, graduates of AACSB-accredited schools such as the Brennan School of Business, are more marketable to prospective employers.

The Brennan School of Business has also achieved accreditation for its Master of Business Administration, its Master of Science in Accounting and its undergraduate programs in accounting, business administration and international business from the Accreditation Council for Collegiate Business Schools and Programs (ACBSP), demonstrating that it has met standards of business education that promote teaching excellence.

Additionally, Dominican University is accredited by The Higher Learning Commission of the North Central Association of Colleges and Schools.
