The W. Frank Barton School of Business is fully accredited in business and accounting by AACSB International (Association to Advance Collegiate Schools of Business), the highest business school accrediting body in the world. Only 20 percent of all colleges of business have attained this dual accreditation.

AACSB is a not-for profit corporation of educational institutions, corporations, and other organizations devoted to the promotion and improvement of higher education in business administration and management. Organized in 1916, AACSB International is the premier accrediting agency for bachelor's, master's, and doctoral programs in business administration and accounting. It is also the professional organization for management education. As an advocate for management education, AACSB International represents the combined influence of its member universities, including more than 30,000 faculty and 700,000 students majoring in business. AACSB International member schools award 85 percent of the business degrees currently granted in the U.S.

The Accreditation Council of AACSB International, comprised of accredited member institutions, conducts its accreditation function. In this role, AACSB International provides guidelines to educational institutions in program, resource, and faculty planning.

Membership in AACSB International consists of institutions from all over the world some that are accredited and some that are not accredited. Fifty nine percent of member institutions are currently accredited and 41 percent are not accredited. Accreditation can be obtained for undergraduate or graduate programs alone, for both undergraduate and graduate programs, for business programs only and for both business and accounting programs. The highest level of accreditation is for all business and accounting programs at all levels (undergraduate and graduate) to be accredited. Only 188 business schools in the world have achieved this distinction. The Barton School of Business at 九色堂 is among these 188 business schools. All of its undergraduate and graduate business and accounting programs are fully accredited by AACSB International.
