The federal government’s civilian workforce faces large losses over the next several years, primarily through retirements. Expected retirements in the SES, which generally represents the most senior and experienced segment of the workforce, are expected to be even higher than the governmentwide rates. In our January 2003 report, we estimated that more than half of the government’s 6,100 career SES members on board as of October 2000 will have left the service by October 2007. Estimates for SES attrition at 24 large agencies showed substantial variations in both the proportion that would be leaving and the effect of those losses on the gender, racial, and ethnic profile. We estimated that most of these agencies would lose at least half of their corps. The key source of replacements for the SES—the GS-15 and GS-14 workforce—also showed significant attrition governmentwide and at the 24 large agencies by fiscal year 2007. While this workforce is generally younger, and those who leave do so for somewhat different reasons than SES members, we estimate that almost half, 47 percent, of the GS-15s on board as of October 2000 will have left federal employment by October 2007 and about a third, 34 percent, of the GS-14s will have left. While past appointment trends may not continue, they do present a window into how the future might look. In developing our estimates of future diversity of the SES corps, we analyzed appointment trends for the federal government and at 24 large agencies to determine the gender, racial, and ethnic representation of the SES corps in 2007 if appointment trends that took place from fiscal years 1995 through 2000 continued. We found that, governmentwide, the only significant change in diversity by 2007 would be an increase in the number of white women, from 19.1 to 23.1 percent, and a corresponding decrease in white men, from 67.1 to 62.1 percent. The proportion of the SES represented by minorities would change very little, from 13.8 to 14.5 percent. Table 1 presents the results by gender, racial, and ethnic groups of our simulation of SES attrition and projection of SES appointments using recent trends. The table also shows that the racial and ethnic profile of those current SES members who will remain in the service through the 7- year period will be about the same as it was for all SES members in October 2000. This is because minorities are projected to be leaving at essentially the same rate overall as white members. Thus, any change in minority representation will be the result of new appointments to the SES. However, as the last columns of table 1 show, if recent appointment trends continue, the result of replacing over half of the SES will be a corps whose racial and ethnic profile changes very little. The outlook regarding gender diversity is somewhat different—while the percentage represented by SES white women is estimated to increase by 4 percentage points, the percentage of minority women is estimated to increase by .5 percentage point—from 4.5 to 5.0 percent. While white men are estimated to decrease by 5 percentage points, minority men are estimated to increase by .2 percentage point, from 9.3 to 9.5 percent. The results of our simulation of SES attrition and our projection of appointments to the SES over the 7-year period showed variation across the 24 Chief Financial Officers (CFO) Act agencies, as illustrated in table 2. However, as with the governmentwide numbers, agencies tend to increase the proportion of women in the SES, particularly white women, and decrease the proportion of white men. The proportion represented by minorities tended to change relatively little. Our estimates of SES attrition at individual agencies by gender, racial, and ethnic groups are likely to be less precise than for our overall SES estimates because of the smaller numbers involved. Nevertheless, the agency-specific numbers should be indicative of what agency profiles would look like on October 1, 2007, if recent appointment trends continue. The gender, racial, and ethnic profiles of the career SES at the 24 CFO Act agencies varied significantly on October 1, 2000. The representation of women ranged from 13.7 percent to 36.1 percent with half of the agencies having 27 percent or fewer women. For minority representation, rates varied even more and ranged from 3.1 percent to 35.6 percent with half of the agencies having less than 15 percent minorities in the SES. Our projection of what the SES would look like if recent appointment trends continued through October 1, 2007, showed variation, with 12 agencies having increased minority representation and 10 having less. While projected changes for women are often appreciable, with 16 agencies having gains of 4 percentage points or more and no decreases, projected minority representation changes in the SES at most of the CFO Act agencies are small, exceeding a 2 percentage point increase at only 6 agencies. At most agencies, the diversity picture for GS-15s and GS-14s is somewhat better than that for the SES. To ascertain what the gender, racial, and ethnic profile of the candidate pool for SES replacements would look like, we performed the same simulations and projections for GS-15s and GS-14s as we did for the SES. Over 80 percent of career SES appointments of federal employees come from the ranks of GS-15s. Similarly, over 90 percent of those promoted to GS-15 are from the GS-14 workforce. Table 3 presents the results of our analysis for GS-15s, and table 4 presents the results for GS-14s. The results show a somewhat lower proportion of this workforce will leave. Minority representation among those GS-15s who remain by 2007 will be about the same as it was at the beginning of fiscal year 2001, indicating that whites and minorities will leave at about the same rates. However, the proportion of minority GS-14s would increase somewhat (by 1.5 percentage points) and the proportion of both grades represented by white and minority women will also increase. Moreover, if recent promotion trends to GS-15 and GS-14 continue, marginal gains by almost all of the racial and ethnic groups would result. Our simulation shows that significant numbers of current minority GS-15s and GS-14s will be employed through fiscal year 2007, and coupled with our projection of promotions, shows there will be substantial numbers of minorities at both the GS-15 (8,957) and GS-14 (15,672) levels, meaning that a sufficient number of minority candidates for appointment to the SES should be available. With respect to gender, the percentage of white women at GS-15 is projected to increase by 2.6 percentage points to 22 percent and at GS-14 by 0.9 percentage point to 23.5 percent. The proportions of minority women will increase by 0.9 percentage point to 6.5 percent for GS-15s and 0.5 percentage point to 8.1 percent for GS-14s, while those for minority men will increase 0.8 percentage point to 10.8 percent for GS-15s and 0.5 percentage point to 10.7 percent for GS-14s. At 60.6 percent, white men will represent 4.2 percentage points less of GS-15s and, at 57.5 percent, 2.1 percentage points less of GS-14s than in fiscal year 2001. Again, our estimates for the GS-15 and GS-14 populations at individual agencies are likely to be less precise than our governmentwide figures because of the smaller numbers involved but should be indicative of what agency profiles would look like in October 2007. During fiscal years 2001 through 2007, the wave of near-term retirements and normal attrition for other reasons presents the federal government with the challenge and opportunity to replace over half of its career SES corps. The response to this challenge and opportunity will have enormous implications for the government’s ability to transform itself to carry out its current and future responsibilities rather than simply to recreate the existing organizational structures. With respect to the challenge, the federal government and governments around the world are faced with losses that have a direct impact on leadership continuity, institutional knowledge, and expertise. Focusing on succession planning, especially at the senior levels, and developing strategies that will help ensure that the SES corps reflects diversity will be important. We have gained insights about selected succession planning and management practices used by other countries that may be instrumental for U.S. agencies as they adopt succession planning and management strategies. We found that leading organizations engage in broad, integrated succession planning and management efforts that focus on strengthening both current and future organizational capacity. As part of this approach, these organizations identify, develop, and select their people to ensure an ongoing supply of successors who are the right people, with the right skills, at the right time for leadership and other key positions. Succession planning is also tied to the federal government’s opportunity to change the diversity of the SES corps through new appointments. Leading organizations recognize that diversity can be an organizational strength that contributes to achieving results. By incorporating diversity program activities and objectives into agency succession planning, agencies can help ensure that the SES corps is staffed with the best and brightest talent available regardless of gender, race, or ethnicity. As stated earlier, the succession pool of candidates from the GS-15 and GS-14 levels should have significant numbers of minority candidates to fill new appointments to the SES. It will be important to identify and nurture talent from this workforce and other levels in agencies early in their careers. Development programs that identify and prepare individuals for increased leadership and managerial responsibilities will be critical in allowing these individuals to successfully compete for admission to the candidate pool for the next level in the organization. Succession planning and management is starting to receive increased attention from the Office of Management and Budget (OMB) and OPM, and we have also seen a positive response from these leadership agencies in developing and implementing programs that promote diversity. In commenting on our January 2003 report, OPM concurred with our findings on SES attrition and diversity and said it welcomed the attention the report brings to a critical opportunity facing the federal workforce and federal hiring officials.
