Which document is used to determine if information is classified?

The Security Classification Guide is the document specifically designed to assist individuals in determining whether information should be classified. It provides clear criteria and guidelines regarding the classification levels that may apply to certain types of information based on various factors such as national security implications, specific program requirements, and the classification categories (e.g., Confidential, Secret, Top Secret).

The guide typically outlines the conditions under which information must be classified and serves as a reference for security personnel and program managers when making classification decisions. It ensures consistent application of classification standards across the organization and helps to protect sensitive information that, if disclosed, could harm national security or defense interests.

In contrast, the other options do not serve this primary purpose:

• Classified Information Guidelines may provide general principles about handling classified information but do not specifically determine classification status.
• A Compliance Directive relates to adherence to regulatory requirements but does not address classification issues directly.
• An Authorization Certificate is generally used to grant access to classified information rather than determine whether the information itself is classified.
