A diverse Senior Executive Service (SES), which generally represents the most experienced segment of the federal workforce, can be an organizational strength by bringing a wider variety of perspectives and approaches to policy development and decision making. In January 2003, GAO provided data on the diversity of career SES members as of October 2000 (GAO-03-34). In March 2000, GAO reported similar data for the Postal Career Executive Service (PCES) as of September 1999 (GAO/GGD-00-76). In its 2003 report, GAO also projected what the profile of the SES would be in October 2007 if appointment and separation trends did not change. In response to a request for updated information on diversity in the SES and the senior ranks of the U.S. Postal Service, GAO is providing data on race, ethnicity, and gender obtained from the Office of Personnel Management's (OPM) Central Personnel Data File and the Postal Service for (1) career SES positions as of the end of fiscal year 2007 and the SES developmental pool (i.e., GS-15 and GS-14 positions) as well as a comparison of actual fiscal year 2007 data to projections for fiscal year 2007 that GAO made in its 2003 report, and (2) the PCES, the Executive Administrative Schedule (EAS), and EAS participants in the Corporate Succession Planning (CSP) program. GAO also describes the process that executive agencies and the Postal Service use to select members into their senior ranks.
