A statement of record issued by the Government Accountability Office with an abstract that begins "Several agencies have key roles and responsibilities in the multi-phased personnel security clearance process, including the Director of National Intelligence (DNI) who, as the Security Executive Agent, is responsible for developing policies and procedures related to security clearance investigations and adjudications, among other things. The Deputy Director for Management at the Office of Management and Budget chairs the Performance Accountability Council that oversees reform efforts to enhance the personnel security process. The security process includes: the determination of whether a position requires a clearance, application submission, investigation, and adjudication. Specifically, agency officials must first determine whether a federal civilian position requires access to classified information. After an individual has been selected for a position that requires a personnel security clearance and the individual submits an application for a clearance, investigators—often contractors—from the Office of Personnel Management (OPM) conduct background investigations for most executive branch agencies. Adjudicators from requesting agencies use the information from these investigations and federal adjudicative guidelines to determine whether an applicant is eligible for a clearance. Further, individuals are subject to reinvestigations at intervals based on the level of security clearance."
