Organization and Staffing

CBO's organization consists of the Office of the Director and nine divisions.

The Speaker of the House of Representatives and the President pro tempore of the Senate jointly appoint CBO's Director, after considering recommendations from the two Budget Committees. Directors are appointed for four-year terms and may be reappointed to the position; in addition, a Director serving at the expiration of a term may continue to serve until a successor is appointed. The Budget Act specifies that CBO's Director is to be chosen without regard to political affiliation. The agency has had 10 Directors and several Acting Directors.

The rest of CBO's staff is appointed by the Director solely on the basis of professional competence, without regard to political affiliation. The agency has about 270 staff members, mostly economists or public policy analysts with advanced degrees. The agency also employs lawyers, information technology specialists, editors, and people with other areas of expertise that contribute to the agency's mission. Many of them have extensive experience in their subject areas, including years of work at CBO.

CBO's collegial work environment and flat organizational structure foster collaboration and teamwork across and within divisions. For example, reports produced by analysts in several divisions rely on economic projections prepared by the Macroeconomic Analysis Division and on cost estimates and budget projections developed by the Budget Analysis and Tax Analysis Divisions. Similarly, budget projections and cost estimates prepared by the Budget Analysis and Tax Analysis Divisions draw on models and analyses produced by other divisions.

Office of the Director

CBO’s Director leads the agency and is supported in that effort by a group of senior staff, members of the Office of Communications, and members of the Office of General Counsel.
