What type of classification is generated when a classified document is used as source material for a new document?

The correct answer is derivative classification. When a classified document is used as source material for creating a new document, the classification level of the original document must be applied to the new document. This process is known as derivative classification because the new document derives its classification from the original source.

Derivative classification is essential in maintaining the integrity and protection of classified information. It allows for the continued safeguarding of sensitive details while permitting the development of new documents based on previously classified materials. This ensures that the information remains protected according to the same guidelines and restrictions as the original classified source.

The other classifications mentioned, such as permanent, temporary, and interim classifications, have specific contexts and durations that don’t apply to the process described in the question. Permanent classification refers to information that is deemed permanently classified due to its sensitivity. Temporary classification applies to information that is classified for a limited duration. Interim classification is related to information that requires immediate classification but is later subjected to review and possible change. These classifications do not represent the act of using existing classified material to derive a new document, which is why derivative classification is the correct choice in this context.
