What does derivative classification involve?

Derivative classification involves the use of existing classified information to create new documents or materials. This process requires individuals to assess and apply appropriate classification markings based on the original source material they are working with. When classified information is utilized to produce new documents, the derivative classifier must ensure that the classification levels and markings are consistent with the original sources' classifications, in accordance with applicable laws and regulations.

The other choices represent activities that do not accurately define derivative classification. For instance, creating new information from unclassified sources does not involve using classified information at all. Translating classified documents is focused on language conversion rather than the creation of new classified content. Fact-checking classified content pertains to verifying information rather than deriving new classified materials from existing ones. Thus, the essence of derivative classification clearly lies in the creation of new documents based on the re-use of already classified information.
