Which of the following is NOT a step in derivative classification?

The process of derivative classification involves specific steps to ensure that classified information is handled appropriately. Making the initial determination for protection involves reviewing information to see if it qualifies for classification under existing guidelines and ensuring appropriate safeguards are applied. Documenting sources thoroughly is essential in derivative classification to maintain transparency and accountability, ensuring that the origin of classified information is clear. Marking according to classification guidelines ensures that the information is labeled properly according to its classification level, which is critical for protecting sensitive data.

However, making recommendations for others to mark new documents is not a step in the derivative classification process. Derivative classifiers are responsible for making their own determinations based on established guidelines and criteria but do not have the authority to dictate how others should classify or mark documents. Each derivatives classifier must independently assess and classify information based on their own judgment and the guidelines provided by their organization. Therefore, this option does not align with the established procedures for derivative classification.
