Derivative classification means incorporating, paraphrasing, restating, or generating in new form information that is already classified, and marking the newly developed material consistent with the classification markings that apply to the source information. While working with classified information, individuals sometimes generate or create new documents and materials based upon that classified information. These individuals who reproduce, extract, or summarize classified information, or who apply classification markings derived from the source material or as directed by a classification guide, need not possess original classification authority. The newly created documents must be classified based upon the classification level of the information from which the new document was developed.
