The Intelligence Authorization Act (IAA) for Fiscal Year (FY) 2010(1) requires the President to submit an annual Report on Security Clearance Determinations to Congress.
The IAA directs this report to include the number of United States Government (USG) employees who held a security clearance at each level as of October 1 of the preceding year and the number of USG employees who were approved for a security clearance at each level during the preceding fiscal year. Similar data pertaining to USG contractors is also required. Also, for each element of the Intelligence Community (IC), in-depth security clearance timeliness determination metrics are required. In response to these IAA requirements, the Office of the Director of National Intelligence (ODNI) has prepared this 2015 Report on Security Clearance Determinations consistent with the security clearance data requirements as outlined by the categories listed below.
