Which document outlines the security clearance process for government employees?

The correct choice highlights Executive Order 12968, which specifically addresses the security clearance process for federal employees and sets forth the guidelines and procedures for determining eligibility for access to classified information. This order emphasizes the importance of equitable and systematic assessments of an individual's background, encapsulating the principles of suitability and trustworthiness essential for positions requiring security clearances.

Executive Order 12968 introduced key elements such as the criteria for making determinations, the importance of continuous evaluation, and the rights of individuals undergoing the process. It also provides clarity on factors that may impact an individual's eligibility for clearance, ensuring a comprehensive and fair evaluation.

The other executive orders, while related to security and personnel vetting, focus on different aspects of security policy or the management of classified information and do not solely delineate the security clearance process applicable to government employees.
