Security Fundamentals Professional Certification (SFPC) Practice Test

Which is not a qualifying criterion for personnel in nuclear weapons positions?

1. Individual must be a U.S. Citizen

2. Individual has a security clearance eligibility

3. Individual is subject to periodic reinvestigation every three years

4. Individual must be continuously evaluated

The correct answer is: Individual is subject to periodic reinvestigation every three years

In the context of qualifying criteria for personnel in nuclear weapons positions, option C indicates a misconception regarding the reinvestigation cycle. While periodic reinvestigation is indeed a part of maintaining security clearances, the specific timeframe of "every three years" does not apply universally across all personnel in nuclear weapons positions. Instead, the criteria for personnel involved with nuclear weapons typically include being a U.S. citizen, having the appropriate security clearance eligibility, and undergoing continuous evaluation. Continuous evaluation is particularly important in managing the ongoing trustworthiness of individuals who have access to sensitive materials; this process checks key indicators of reliability and fitness for duty continuously, rather than adhering to a fixed timeline. Thus, the correct answer emphasizes that the specific three-year interval for reinvestigation doesn't align with the established practices for personnel in nuclear weapons roles, making it the qualifier that does not fit with the requirements.
