What is a typical SCI compartment code notation?

• A. SECRET//SCI [CODEWORD]
• B. TS//SECRET [CODE]
• C. TS//SCI [CODE]
• D. SCI [CODE]

Answer: (C)

A typical SCI compartment code notation combines a clearance level, the SCI designation, and a compartment identifier in brackets. You need both a Top Secret clearance and SCI access, and you specify the exact SCI compartment with the bracketed code. That makes the standard form TS//SCI [CODE] the correct choice: it shows Top Secret, SCI, and the specific compartment in one clean format.

If you see a notation that uses SECRET with SCI, that implies a lower clearance level than is standard for SCI, which isn’t correct for how SCI marks are applied. If you see a format that lists the compartment code after SECRET or omits SCI entirely, it’s missing the SCI designation, which is essential. If the notation lacks any clearance level and only shows SCI with a bracketed code, it doesn’t indicate the required top clearance to access SCI information.
