WSB-NLU is accredited by two foreign institutions: North Central Association of Colleges and Schools and the International Assembly  of Collegiate Business Education.

In 2000, as  part of the cooperation between WSB-NLU in Nowy Sącz and NLU in Chicago, the Nowy Sącz School was included in the process of the periodical accreditation that covered all NLU programs. During this process, WSB-NLU was visited by the evaluation team and, based on its recommendation, the WSB-NLU full-time undergraduate program was accredited by the North Central Association of Colleges and Schools, located in Chicago.

Another accreditation was granted to the programs in business offered by  WSB-NLU by the International Assembly of Collegiate Business Education.

WSB-NLU is also a member of the CEEMAN - an association of business schools from Central and Eastern Europe.
