What are the prerequisites for accessing Sensitive Compartmented Information (SCI)?

Accessing Sensitive Compartmented Information (SCI) requires a Top Secret clearance because this level of clearance ensures that individuals have undergone a thorough background investigation, which is necessary given the sensitive nature of the information. Additionally, indoctrination into the SCI program is crucial, as it provides specific training and briefing on the handling and protection of SCI. This indoctrination ensures that personnel understand the strict protocols associated with accessing this type of information, which is compartmentalized for national security reasons.

While other factors may play a role in the broader context of security clearances, they do not specifically meet the stringent requirements for accessing SCI.
