Which of the following is NOT a function of derivative classification?

The function of derivative classification includes identifying the need to protect information that has already been classified and deriving new classified documents from existing authorized sources. Therefore, creating new classified documents, compiling classified data into new formats, and maintaining the classification of existing materials are all functions carried out under derivative classification.

However, the choice that is not a function of derivative classification is the initial determination that information requires protection. This responsibility typically falls under the domain of original classification, where an individual or authority decides if information should be classified in the first instance. Derivative classification specifically focuses on how to utilize and manage information that has already been classified rather than making the initial classification decisions.
