We will begin the subject peer review in October 2020. The Government Auditing Standards require that an audit organization performing audits in accordance with the Government Auditing Standards undergo an external peer review every three years by an organization that is independent of the organization being reviewed. Our objective of this external peer review is to determine, for the period ending September 30, 2020, whether the quality control system for the Missile Defense Agency Internal Review Office was designed to provide reasonable assurance that the policies and procedures related to the system of audit quality are suitably designed, operating effectively, and complied with in practice.
