Where can you find a listing of specific information elements that identify their classification, reason for classification, downgrading, and declassification information?

The Security Classification Guide (SCG) is the correct source for obtaining a comprehensive listing of specific information elements that indicate their classification status, rationale for that classification, as well as procedures for downgrading and declassification. SCGs are tailored to particular types of information or specific subjects and provide detailed guidance on how to classify information appropriately based on established criteria.

These guides help personnel in understanding how to handle classified information in accordance with national security requirements, ensuring consistency and compliance with applicable laws and regulations. They serve as essential references for those engaged in derivative classification, enabling the correct identification of why certain information is classified and outlining the pathways for its eventual downgrading or declassification over time.

In contrast, other sources such as the Classified Document Archive, Information Security Manual, or NSA Guidelines do not specifically provide the structured and detailed classification instructions that SCGs are designed to deliver.
