Which tier includes Top Secret and SCI?

• A. High Tier
• B. Low Tier
• C. Moderate Tier
• D. No Tier

Answer: (A)

High Tier is the level that covers the most sensitive information, including Top Secret and SCI. Top Secret represents the highest standard of classification, and SCI (Sensitive Compartmented Information) is a set of highly restricted compartments that require not only Top Secret clearance but also explicit need-to-know and compartmentalized access. Because both are associated with the highest level of sensitivity and the strictest access controls, they’re categorized together in the High Tier. The other options imply lower levels of sensitivity or no tier, which wouldn’t fit the protection requirements for Top Secret and SCI.
