The organization is about 100 years old and was formed by the Federal Government of USA in 1917 as the Northwest Association of Secondary and Higher Schools. In 1974 the association changed its name to the Northwest Association of Schools and Colleges and later in 2000 it became the Northwest Association of Schools and Colleges and Universities. This was actually a consolidated body for schools as well as higher-education institutions and this body bifurcated into two different accreditation agencies in 2004. The Northwest Association of Accredited Schools started handling the accreditation of schools and the Northwest Commission on Colleges and Universities took charge of the accreditation of institutions of higher education.
NWAC or Northwest Accreditation Commission is the current name of Northwest Association of Accredited Schools and it has presence across a lot of countries.
In January 2012 the Northwest Accreditation Commission became a division of AdvancED, which was formed by the North Central Association Commission on Accreditation and School Improvement and the Southern Association of Colleges and Schools Council on Accreditation and School Improvement. Now three of the premier US Regional Ccrediting agencies for school accreditation are a part of AdvancED. AdvancED is now present in more that 32,000 schools across over 70 countries.
After a long investigation it proves that Northwest Accreditation commission (NWAC) board is valid.
