STEPP Marking Classified Information Practice Exam 2025 – Comprehensive All-in-One Guide to Exam Mastery

Derivative classifiers within the Department of Defense (DoD) include all cleared and trained DoD and authorized contractor personnel. This classification encompasses a broad range of individuals who have been granted the necessary security clearances and have received formal training in classification practices.

The rationale behind including all cleared and trained personnel is that derivative classifiers are responsible for applying classification markings to information derived from currently classified sources. This means that they play a vital role in recognizing and appropriately marking information that derives from or is based on existing classified material. By ensuring that both government employees and authorized contractor personnel are included, the DoD emphasizes the importance of comprehensive training and responsibility in maintaining the integrity of classified information.

This approach allows for a more robust system of safeguarding sensitive information, as it allows for diverse expertise and input from a wider range of personnel involved in national security operations.
