The three big mistakes in the 2020 Plum Book

By Emma Jones and Christina Condreay

For most people, the only way to find out who is serving in the top decision-making positions in government is to reference a document called the Plum Book. Unfortunately, this document has significant procedural and factual problems and could be greatly improved.

The Plum Book remains the best source of valuable information about our senior government leaders, including names, position titles, salary information and term expiration dates. It contains information on more than 4,000 political appointees – about 1,200 of whom are subject to Senate confirmation – along with thousands of other jobs filled by senior career officials in the federal civil service.

However, the Plum Book is only published every four years. This means that information about some positions is outdated before it is even made available to the public. Even more problematic, the most recent version of the Plum Book contains numerous errors and shortcomings. Here are three of the biggest mistakes in the latest Plum Book published on Dec. 1, 2020:

1. Some agencies are omitted without explanation.

The following agencies appear in the 2016 Plum Book, but not in the 2020 edition. These organizations remain active and are funded. Combined, they have about a dozen presidentially appointed positions requiring Senate confirmation and between 60 and 100 positions not requiring Senate confirmation.

  • Department of Agriculture Office of the Inspector General.
  • Office of the Director for National Intelligence.
  • Administrative Conference of the United States.
  • Architectural and Transportation Barriers Compliance Board (United States Access Board).
  • Federal Financial Institutions Examination Council.
  • International Boundary Commission: United States and Canada.
  • Presidio Trust.
  • Privacy and Civil Liberties Oversight Board.
  • The John F. Kennedy Center for the Performing Arts.
  • Utah Reclamation Mitigation and Conservation Commission.

2. The Plum Book is missing positions.

Other agencies appear in the 2020 Plum Book, but are missing key positions. Agencies with incomplete position totals include the National Endowment for the Arts, the United States Holocaust Memorial Council and the United States Postal Service. Scholars at Vanderbilt University have identified additional positions that were missing from both the 2016 and 2020 Plum Books. In total, hundreds of positions are not included in the 2020 Plum Book.

3. The appendix does not match the rest of the document.

The 2020 Plum Book contains appointment information for 170 agencies, while Appendix 1 provides summary counts for 158 distinct organizations. The 12 agencies excluded from the appendix include four legislative branch agencies and the Harry S. Truman Scholarship Foundation. Additionally, the last six agencies listed alphabetically in the Plum Book are also missing from the appendix in addition to part of the White House that employs 82 people.

The 2020 Plum Book also only counts filled positions in the Senior Executive Service, a change from previous editions. This means that roughly 1,100 vacant positions out of about 8,000 of the government’s senior executives are not counted in the agency position totals listed in the appendix.


Since the Plum Book is only updated every four years, these mistakes could remain uncorrected until 2024. The Plum Book also does not include supporting methodological information or documentation of any changes made from previous editions or explanations for omissions. But this is not the first time it has been filled with errors.

Fortunately, there are several fundamental improvements that would make the Plum Book more useful. First, the information should be updated as close to real-time as possible. Second, errors should be fixed as soon as they are caught. Third, while the Plum Book is available online as a PDF and through a few other options, it should be available in a more downloadable and machine-readable format. Fourth, providing data based on the self-identified demographic information of individuals holding positions listed in the Plum Book would help shed light on how well the government is doing in attracting and retaining a diverse workforce. Proposed legislation called the PLUM Act would accomplish all these objectives.

These improvements would bring increased transparency and accountability to the federal government by helping ensure the American people know who is serving in top decision-making positions. In addition, the PLUM Act would provide timely information on Senate-confirmed positions and whether they are vacant or filled by an acting official, providing transparency and reinforcing accountability under the Vacancies Act. On June 29, 2021, the PLUM Act was reported out of the House Committee on Oversight and Reform.

Congress should pass the PLUM Act to modernize the Plum Book and prevent major mistakes from occurring in future editions of a critically important government document.
