Derivative Classification Training Practice Exam

What concept is illustrated when both source and new documents state the same information?

1. Interpretation

2. Extension

3. Declassification

4. Redaction

The correct answer is: Extension

When both source and new documents state the same information, it illustrates the concept of extension. Extension in derivative classification occurs when information from a classified source is included in a new document without altering its content, essentially maintaining the original classification while extending the relevance or applicability of that information. This is a common practice when further dissemination or application of existing classified data is necessary for continuity and operational needs. In this scenario, the new document can still be classified because it contains information that is already classified in the source document. Both documents collectively provide a comprehensive understanding of the classified content and help to ensure that sensitive information is protected appropriately across multiple platforms or discussions.
