Derivative Classification
Derivative classification is the act of incorporating, paraphrasing, restating, or generating in new form information that is already classified, and marking the newly created material to reflect the classification of its source.
Derivative classification is what happens when someone creates a new record by drawing on information that an original classification authority has already classified. Unlike original classification, which is an initial determination that information requires protection, derivative classification simply carries forward existing decisions. The person doing it does not decide that the information is sensitive; they recognize that it already is and apply the appropriate markings, citing the source document or a security classification guide.
This matters in recordkeeping because the overwhelming majority of classified material is created derivatively, and errors propagate. A mismarked or unsourced derivative record can over-classify content (frustrating later access and review) or under-protect it. Accurate source citations and markings also shape downstream disposition, declassification scheduling, and responses to access requests.
For example, an analyst quoting a classified intelligence report inside a new briefing memo is classifying derivatively; the memo inherits the source’s level and is marked accordingly, with the originating reference recorded so future reviewers can trace and reassess it.
