SELECTING A CREDENTIAL EVALUATION SERVICE 

If the U.S. school or institution recommends that you use a specific credential evaluation service, then use the service, or one of the services, recommended by the international admissions office. 

If not, then you can select a credential evaluation service yourself.  You can search for credential evaluation services on the Internet, but you should know that there is no federal or state regulation of such services.  However, there are two national associations of credential evaluation services that have published standards for membership, affiliations to national and international higher education associations and are frequently linked to and used by federal agencies, state agencies, educational institutions and employers.

National Association of Credential Evaluation Services (NACES) is an association of 19 credential evaluation services with admission standards and an enforced code of good practice. (of which WES is a member) 

Association of International Credentials Evaluators (AICE) is an association of 10 credential evaluation services with a board of advisors and an enforced  code of ethics.

Neither the U.S. Department of Education nor USNEI endorses or recommends any individual credential evaluation service.
