The Western Association of Schools and Colleges (WASC) Senior College and University Commission (WSCUC), also known as ‘the Commission’, is a regional accrediting agency, established for the purposes of accrediting senior colleges and universities throughout California, Hawaii, and the Pacific and a limited number of international institutions. WSCUC is recognized by the U.S. Department of Education (USDE) and by the Council for Higher Education Accreditation (CHEA) as a reliable authority concerning the quality of education provided by member institutions of higher education offering the associate degree, baccalaureate degree and post-baccalaureate degrees.

WSCUC was originally formed on July 1, 1962 to evaluate and accredit schools, colleges, and universities in California, Hawaii, Guam, American Samoa, the Federated States of Micronesia, the Republic of Palau, and the Commonwealth of the Northern Mariana Islands. Three separate accrediting commissions serve this region: one for K-12 schools (ACS WASC), one for community and junior colleges (ACCJC), and one for senior colleges and universities (WSCUC).
