Which factors can negatively impact an employee’s eligibility for a security clearance?

The correct answer highlights several factors that are critical in assessing a person's eligibility for a security clearance. Financial issues can indicate a potential vulnerability to bribery or coercion, making them a significant concern for security clearance evaluations. Substance abuse may impair judgment and reliability, further questioning an individual's suitability for access to sensitive information. Foreign connections can create potential conflicts of interest or raise concerns over the influence of foreign entities, posing a risk to national security.

In contrast, the other options present traits or achievements that generally support an individual's qualifications for maintaining a security clearance. Positive work reviews and community service reflect a strong character and commitment to societal responsibilities, while a strong educational background and professional development demonstrate competence and reliability. Additionally, consistent attendance and punctuality are indicative of reliability and professionalism. None of these characteristics would negatively affect someone's clearance eligibility.
