Educational accreditation is a type of quality assurance process under which services and operations of educational institutions or programs are evaluated by an external body to determine if applicable standards are met. If standards are met, accredited status is granted by the appropriate agency.
In most countries the function of educational accreditation is conducted by a government organization, such as a Ministry of Education. In the United States a quality assurance process exists that is independent of government and performed by private non-profit organizations.  Those organizations are formally called accreditors. All accreditors in the US must in turn be recognized by the National Advisory Committee on Institutional Quality and Integrity (NACIQI), which is an advisory body to the U.S. Secretary of Education, in order to receive federal funding and any other type of federal recognition. Therefore, the federal government is the principal architect and controlling authority of accreditation.  The U.S. accreditation process was developed in the late 19th century and early 20th century after educational institutions perceived a need for improved coordination and articulation between secondary and post-secondary educational institutions, along with standardization of requirements between the two levels.   
Accreditation of higher education varies by jurisdiction and may be focused on either or both the institution or the individual programs of study.
Higher education accreditation in the United States has long been established as a peer review process coordinated by accreditation commissions and member institutions. The federal government began to play a limited role in higher education accreditation in 1952 with the reauthorization of the GI Bill for Korean War veterans.  With the creation of the U.S. Department of Education and under the terms of the Higher Education Act of 1965, as amended, the U.S. Secretary of Education is required by law to publish a list of nationally recognized accrediting agencies for higher education.
In the United States, there is no federal government list of recognized accreditation agencies for primary and secondary schools like there is for higher education.[ citation needed] Public schools must adhere to criteria set by the state governments, and there is wide variation among the individual states in the requirements applied to non-public primary and secondary schools.  There are six regional accreditors in the United States that have historically accredited elementary schools, junior high schools, middle schools, high schools, as well as institutions of higher education.  Some of the regional accreditors, such as AdvancED, and some independent associations, such as the Association of Christian Schools International  and Council of Islamic Schools of North America (CISNA) , have expanded their accreditation activity to include schools outside the United States.
