The Low Tier (LT) investigative tier serves as the minimum requirement for which personnel vetting determination?

• A. Granting physical and/or logical access to facilities and making credentialing (HSPD-12) determinations.
• B. Access to Top Secret information only.
• C. Access to Confidential information only.
• D. Appointment to a public trust position.

Answer: (A)

The Low Tier is the baseline screening used to determine who can be trusted to access federal facilities and systems. It establishes the minimum background checks necessary to grant a badge and make credentialing determinations under HSPD-12. This is about physical and logical access, not about handling specific levels of classified information. Higher-tier investigations are required for Top Secret or Confidential access, and public-trust appointments generally involve more comprehensive reviews, so Low Tier is specifically the minimum for facility access and credentialing determinations.
