Which of the following changes in cleared employee status must be reported?

Reporting changes in cleared employee status is essential for maintaining the integrity of national security, as these changes can directly impact an individual’s eligibility to access classified information. Employment termination must be reported because it signifies that a cleared employee is no longer in their position and thus no longer requires access to sensitive information. This action ensures that security clearance statuses are current and that only those actively engaged in work requiring clearance are able to access classified materials.

In contrast, merit increases, job title changes, and performance appraisals, while important for personnel management, do not directly affect an individual's clearance status or their access to classified information. These actions typically do not involve any security concerns that necessitate immediate reporting to the relevant authorities managing the National Industrial Security Program (NISP).
