Obtaining SCI access eligibility.
In order to be considered for SCI eligibility, an applicant must first be nominated for an SCI billet, complete a Single Scope Background Investigation (SSBI), and be approved by the government agency that controls the information. Since SCI encompasses several categories of compartmented information, the Consolidated Adjudication Services (CAS) grant eligibility for access to SCI, and once this eligibility has been established, a person can be granted a special access authorization for a specific category of information within SCI. SCI access eligibility is divided into 3 sensitivity levels and each has a different investigative requirement:
- SSBI without polygraph
- SSBI with Counterintelligence Scope polygraph
- SSBI with Full Scope polygraph
