Title 10, United States Code, Section 1566, (10 U.S.C. Section 1566), as amended, requires the Inspectors General (IGs) of the Army, Navy, Air Force, and Marine Corps to annually review compliance with their own Service's voting assistance programs, review the effectiveness of those programs, and report results to the Department of Defense Inspector General (DoDIG) in time to be reflected in the DoDIG annual report. 10 U.S.C. Section 1566 also requires the DoDIG to report to Congress not later than March 31st of each year on voting assistance programs during the preceding calendar year. In accordance with the law, we received reports from the Army, Naval, Air Force, and Marine Corps IGs covering calendar year 2011. In all cases, the Service IGs provided detail in the following five functional areas: staffing, training, material distribution, communication and information, and command emphasis. We reviews the Service IG reports and certain supporting data, as needed; met with senior IG representatives from the Army, Navy, Air Force and Marine Corps; discussed their data collection procedures; and evaluated the criteria they used as a basis for their conclusions. We also summarized and compiled their reports. Our objective was to report whether the Army, Navy, Air Force, and Marine Corps were complying with their voting assistance programs, and whether those voting assistance programs were effective.
