On working papers, what must each page be marked with?

• A. The highest classification level.
• B. The lowest classification level.
• C. The source's name.
• D. The date only.

Answer: (A)

Marking each page with the highest classification level ensures the page is safeguarded at the most restrictive level of information it contains. Working papers often mix material from multiple sources, some more sensitive than others. If a page includes any highly classified content, the entire page should carry that highest level so anyone handling it applies the correct controls and restrictions. This practice helps prevent accidental exposure or improper sharing and supports proper handling and chain-of-custody. The other options don’t fit because a lowest level would under-protect, a source’s name alone does not convey handling restrictions, and a date only omits necessary classification information.
