Although the National Student Clearinghouse (NSC) is not an approved source for primary source verification, NCQA allows verification of credentials through an agent of an approved source. NSC can serve as an agent for some institutions.
Before using NSC, the organization must obtain documentation of a contractual relationship between it and the approved source (institutions that work with NSC). The contractual relationship must entitle the agent to provide verification of credentials on behalf of the approved source.
