The backlog of security clearance investigations has continued to drop from a 2018 high of 725,000 to a steady state inventory of 200,000, but agencies and contractors continue to struggle with reciprocity issues.
The Defense Counterintelligence and Security Agency is in the process of developing the National Background Investigation Services (NBIS) to replace legacy background investigation IT systems. This IT system is part of the new Trusted Workforce 2.0 framework, meant to consolidate the security clearance process and address problems plaguing the process of obtaining initial clearances and moving cleared employees among agencies. It also establishes a continuous vetting process for security clearance holders.
