DoD Personnel: More Actions Needed to Address Backlog of Security Clearance Reinvestigations, Report to the Chairman, Subcommittee on National Security, Veterans Affairs, and International Relations, Committee on Government Reform, House of Representatives [open pdf - 336KB]
"Historically, DOD has reported a large backlog of overdue reinvestigations.4 In fiscal year 1986, DOD had a backlog of 300,000 overdue reinvestigations that had not been submitted to the Defense Security Service for an update. The backlog has reportedly increased significantly over the past few years due to several factors. First, new standards, approved in 1997, increased periodic reinvestigation requirements by shortening the time interval between reinvestigations for secret clearances from 15 to 10 years and by establishing a new, 15-year periodic reinvestigation requirement for confidential clearances. Second, for 4 years starting in fiscal year 1996, DOD tried to help the Defense Security Service clear up its backlog of pending investigations by imposing quotas on the number of reinvestigations the services and Defense agencies could request. This led to pent-up demand for reinvestigation requests. Finally, in October 1998, the Defense Security Service began having significant difficulties implementing a new automated case control management system. The problems led to reduced productivity and increased completion times."
