Accreditation is a certification of approval.
In some other countries, accreditation may be granted directly from the national government. In the U.S., the government does not accredit schools.

In a few countries of the world, existing Universities of exceptional standing may, with approval of the national government, accredit other smaller or less recognized schools.
