Certificates of Confidentiality (CoC) are issued by the National Institute of Health (NIH) to help researchers protect identifiable research information from forced disclosures such as court orders and subpoenas. They allow researchers to refuse to disclose identifying characteristics about research participants in any civil, criminal, administrative, legislative, or other proceeding, whether at the federal, state, or local level.

Please note, depending on the type of study, the NKU IRB may require that the researcher obtain a Certificate of Confidentiality.
