The Department of the Navy Central Adjudication Facility, a Naval Criminal Investigative Service (NCIS) organization, was responsible for determining who within the Department of the Navy is eligible to hold a security clearance, to have access to Sensitive Compartmented Information (SCI), or to be assigned to sensitive duties. The aggregate body of DoN personnel consists of Active Duty and Reserve components of the United States Navy and Marine Corps, as well as civilians and contractors. In addition, DoN CAF makes SCI eligibility determinations for select contractor personnel. Collateral clearance determinations for contractor personnel are established by DISCO.
