Which PSI does not support clearance eligibility for military?

• A. NACI
• B. SSBI
• C. T3R
• D. NACLC

Answer: (A)

The key idea is recognizing which investigations are actually used to grant access to classified information. A National Agency Check with Inquiries is a lighter, suitability-focused check designed for positions that don’t require a security clearance. It doesn’t meet the depth and scope needed to establish eligibility for a clearance. In contrast, a Single Scope Background Investigation is specifically used to determine Top Secret eligibility, NACLC supports Secret eligibility, and Tier 3R covers reinvestigation to maintain or revalidate clearance. Because of its limited scope and purpose, the National Agency Check with Inquiries is the one that does not support clearance eligibility.
