Accredited Schools is an association based in Boise, Idaho which accredits a variety of schools, including K-12, elementary, middle, and high schools; schools offering distance education; non-degree-granting post-secondary institutions; and special purpose, supplementary education, travel education, and trans-regional schools.

The association identifies its geographic territory as Alaska, Idaho, Montana, Nevada, Oregon, Utah, and Washington, as well as "other geographical areas designated from time to time by the Board of Trustees." The association has accredited schools in other states such as Florida, Iowa, Mississippi, and New York and outside the United States in countries including Costa Rica, Egypt, Kosovo, Macedonia, Saudi Arabia, and Spain.

The Northwest Commission on Colleges and Universities is the recognized regional accreditation agency for post-secondary institutions in the seven-state region served by the Northwest Association of Accredited Schools. As a result of this division of responsibilities, neither the United States Department of Education nor the Council for Higher Education Accreditation recognizes the Northwest Association of Accredited Schools as an accrediting agency for institutions of higher education.
