Perusal of accreditation through the Western Association of Schools and Colleges (WASC) began during the 2009-2010 academic year as reflected in the corresponding academic bulletin. The WASC Senior College and University Commission granted eligibility to Weimar Institute during the 2015-2016 academic year. In February 2017, the institute was granted candidacy status for a period of five years during which the college could advance to initial accreditation if the commission's qualifications were met. According to the March 2017 accreditation progress report, the institute was scheduled to receive a visit from the WASC commission to determine eligibility for initial accreditation in the fall of 2018. In the subsequent commission report, the institute was granted initial accreditation for a period of six years retroactive to January 1, 2018.
