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

The process of derivative classification involves several key steps aimed at ensuring that classified information is properly handled and that new documents derived from classified sources are assigned the appropriate classification markings. The option that is not considered a formal step in this process is making recommendations for others to mark new documents.

At its core, derivative classification requires the classifier to use existing classification guidance, which may involve referencing original classification decisions and applying that context to new documents. Utilizing classification guidance helps maintain consistency and adherence to established protocols.

Reviewing existing documents for reclassification is also an important step, as it ensures that information that may have changed in terms of its sensitivity or classification status can be appropriately updated. Additionally, consulting with experts in the field can provide necessary insights and ensure that the classification process is accurate and reflects current understanding.

In contrast, making recommendations for others to mark new documents is outside the core steps of derivative classification, as it suggests an informal process rather than following standardized procedures, which could lead to inconsistencies and misinterpretations of classification standards. Thus, this option stands apart from the essential steps involved in the derivative classification process.
