GAO Report: Improvements Needed for Federal Workforce Senior Position Data Transparency
Summary
The U.S. Government Accountability Office (GAO) released a report finding that the Office of Personnel Management's (OPM) PLUM Reporting website, which tracks senior federal positions, has data quality issues. GAO recommended OPM improve data collection and reporting to increase transparency for the public and Congress.
What changed
The U.S. Government Accountability Office (GAO) has identified significant deficiencies in the data quality of the Office of Personnel Management's (OPM) Periodically Listing Updates to Management (PLUM) Reporting website. The report, dated February 26, 2026, found that the website, intended to provide transparency on politically appointed and senior federal positions, is missing federal entities and presidentially appointed, Senate-confirmed positions, and inconsistently applies unique identifiers. Errors and duplicative positions were also noted, hindering the public's and Congress's ability to track individuals in key decision-making roles.
GAO recommends that OPM collect missing data, ensure accurate reporting, and proactively engage the public to solicit feedback on the website's utility. The findings suggest that OPM has only partially addressed statutory requirements for transparent government data reporting. Agencies and government oversight bodies should be aware of these data limitations and the ongoing efforts to improve the PLUM Reporting website's completeness and accuracy as a transparency tool.
What to do next
- Review OPM's PLUM Reporting website for data accuracy and completeness related to senior policy and supporting positions.
- Ensure internal reporting aligns with OPM's data requirements and address any identified discrepancies.
- Monitor OPM's progress in implementing GAO's recommendations for data improvement.

Fast Facts
The public needs information about political appointees and other senior federal officials to understand who is accountable for key policy decisions. The PLUM Reporting website, managed by the Office of Personnel Management, is a primary source of information on these senior officials.
We reviewed the quality of the website data. We found some agencies and positions were missing, and that other required information wasn't reported correctly. This could make it more difficult for the public to understand data on the website.
We recommended OPM collect missing data, ensure it's reported accurately, and more.

Highlights
What GAO Found
The Periodically Listing Updates to Management (PLUM) Reporting website, maintained by the Office of Personnel Management (OPM), publishes data on politically appointed and career senior positions for all executive branch agencies and certain legislative branch agencies. As of July 2025, the website reported information on 10,540 positions across 171 federal entities (including agencies, boards, commissions, and other organizations).
GAO found that although OPM had procedures in place to help ensure the quality of data published on the website, the data did not include all elements required by the act. For example, GAO found at least seven federal entities were missing from the data, as well as at least 130 presidentially appointed, Senate-confirmed positions. Additionally, unique identifier numbers used for tracking appointees’ movement within the federal workforce were not applied consistently in the data. GAO also found instances of errors and inconsistencies in the data, such as duplicative positions. Complete and accurate data would help Congress and the public identify and track individuals holding senior positions.
Example of a Duplicative Position on the 2025 PLUM Reporting Website
GAO found that the PLUM Reporting website, and OPM’s efforts to implement the website, only partially addressed three key practices for transparently reporting government data and certain relevant statutory requirements. GAO found:
- OPM did not proactively engage members of the public to solicit information on how they used and valued the website.
- OPM has not yet made the PLUM Reporting data available through its agency data inventory, though it has plans in place to do so.
- OPM did not fully describe the data and their known limitations. Non-governmental stakeholders cited concerns with the website including data timeliness, missing positions or errors, and a lack of potentially useful information. Stakeholders also suggested ways to make the website more valuable to users. By better engaging users and publicizing data quality limitations, OPM can improve the usefulness of the PLUM Reporting website and the data’s value as a transparency tool.
Why GAO Did This Study
Information about the federal government’s senior leaders is a critical tool for the public and Congress to understand who is serving in roles with significant decision-making authority and improve oversight. The PLUM Act of 2022 required OPM to establish a website, referred to as the PLUM Reporting website, to report data on senior positions. The act includes provisions for GAO to review implementation of the act.
This report reviews (1) actions OPM took to ensure federal entities reported data on senior positions that met relevant quality requirements, and (2) the extent to which the PLUM Reporting website addressed key practices for transparently reporting government data and relevant statutes.
GAO analyzed PLUM Reporting data for potential errors and compared data against other information on senior political appointees. GAO reviewed OPM documents and interviewed OPM officials about their efforts to ensure data quality. GAO also interviewed eight stakeholders from academia and civil society organizations about their experience using the website and data. Finally, GAO assessed the website against GAO criteria for data transparency.
Recommendations
GAO is making seven recommendations for OPM to improve the usefulness of the website by implementing a process to identify missing reportable positions, making technical changes to ensure unique identifier numbers are applied consistently, and developing a process for engaging the public, among other recommendations. OPM concurred with the recommendations and described ongoing and planned actions to address them.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
| --- | --- | --- |
| Office of Personnel Management | The Director of OPM should develop and implement a process that provides reasonable assurance that reportable positions are included in the PLUM data.
