Resources for Credentials Verification

The following list of resources has been developed to help organizations identify primary and secondary sources for verifying credentials of health care professionals. If you have any questions regarding primary or secondary source verification, please contact the Accreditation Association at 847/853.6060 or

Primary Source Verification:
Primary Source Verification is documented verification by an entity that issued a credential, such as a medical school or residency program, indicating that an individual's statement of possession of a credential is true. Verification can be done by mail, fax, telephone, or electronically, provided the means by which it is obtained are documented and measures are taken to demonstrate there was no interference in the communication by an outside party.

Secondary Source Verification:
Acceptable secondary source verification is documented verification of a credential through obtaining a verification report from an entity listed below as acceptable on the basis of that entity having performed the primary source verification. Information received from any of these sources must meet the same transmission and documentation requirements as outlined above for primary sources

Another health care organization, such as a hospital or group practice, that has carried out primary source or acceptable secondary source verification, provided it supplies directly, without transmission or involvement by the applicant or other third party, original documents or photocopies of the verification reports it has relied upon. A statement that it has performed verification is not sufficient.

Documents, diplomas, certificates or transcripts provided directly by the applicant rather than by the primary or secondary source are not acceptable.

The following are a few internet resources for verification of credentials:
