Which of the following is NOT an authorized source for derivative classification?

• A. Unconfirmed source
• B. DD Form 254
• C. Security Classification Guide
• D. Source document

Answer: (A)

Derivative classification rests on using official, vetted guidance to assign a proper classification to new information. An unconfirmed source lacks that verified authority, so it cannot serve as the basis for derivative classification. The legitimate pathways include source documents that carry their own classification markings, and Security Classification Guides that provide approved rules for how information should be categorized. In contract contexts, a DD Form 254 offers contract-specific classification guidance and is considered an authorized source. These sources ensure consistency and protect information appropriately. Relying on unverified or informal sources can lead to incorrect classifications and security risks.
