GAO's Name Change and Other Provisions of the GAO Human Capital Reform Act of 2004
Effective July 7, 2004, the GAO's legal name became the Government Accountability Office. The change, which better reflects the modern professional services organization GAO has become, is the most visible provision of the GAO Human Capital Reform Act of 2004, Pub. L. 108-271, 118 Stat. 811 (2004).
