What is an administrative determination of an individual’s eligibility for access to classified information called?

The term for an administrative determination of an individual’s eligibility for access to classified information is personnel security clearance. This process involves assessing a person's background, character, and associations to determine whether they can be trusted with sensitive information.

Personnel security clearances ensure that individuals who have access to classified materials are reliable and do not pose a security threat. This type of clearance is essential within various organizations, especially government entities and those contractors handling sensitive data.

While there are other types of security clearances mentioned, such as industrial, national, and communications security clearances, they refer to specific contexts or types of information rather than the broad administrative process of determining eligibility for access to classified information. Personnel security clearance encompasses the complete evaluation needed to grant or deny an individual the right to access classified data based on security regulations and guidelines.
