What is the purpose of an Investigation Review Board (IRB)?

The purpose of an Investigation Review Board (IRB) is to evaluate personnel security clearance cases. This group is responsible for reviewing the results of security investigations and making recommendations or decisions regarding the suitability of individuals for access to classified information or facilities. By thoroughly assessing cases, the IRB ensures that all personnel who have access to sensitive information meet the necessary security standards and regulations, thus maintaining the integrity of national security initiatives.

Other options pertain to different aspects of security operations. Conducting regular security drills focuses on preparedness for emergency situations, managing facility access controls is about overseeing who can enter secure areas, and developing training programs for security personnel involves the instruction and education of staff but does not relate specifically to personnel clearance evaluations.
