Review of Questionable Background Investigations Performed by the Office of Personnel Management's Former Contractor U.S. Investigations Services, Inc.

The HCO should prioritize the reinvestigation of any employee whose most recent background investigation was performed by the USIS during the period March 2008 through September 2012, as determined by this audit.

The HCO should incorporate the guidelines developed by the Director of National Intelligence to assess the quality and completeness of the ROIs provided by the OPM into IRS policies and procedures to guide the HCO Office of Personnel Security in determining whether or not the ROI is complete and may be relied upon in performing its suitability determinations.
