Presidential Appointments & the PAS System — Staffing the Federal Government

Every time a new president takes office, roughly 4,000 political positions turn over — a transition of executive branch leadership with no parallel in any other advanced democracy and that the incoming administration has approximately 75 days (from election to inauguration) to plan. The constitutional foundation is the Appointments Clause (Art. II § 2, cl. 2), which divides officers of the United States into two categories: principal officers (requiring Senate confirmation) and inferior officers (appointable by the President alone, courts of law, or heads of departments if Congress so provides). In practice, this creates a layered system: roughly 1,200 presidentially appointed, Senate-confirmed (PAS) positions at the top; approximately 1,500 Schedule C (non-career excepted service) positions below that; and roughly 700 non-career Senior Executive Service positions — together totaling about 4,000 political positions atop a career federal workforce of approximately 2.1 million. The entire system is documented in the "Plum Book" (formally, "United States Government Policy and Supporting Positions"), published after each election by OPM and the House Oversight Committee.

Legal Authority

• U.S. Const. art. II, § 2, cl. 2 — Appointments Clause; divides officers into principal officers (requiring Senate confirmation) and inferior officers (appointable by the President alone, courts, or department heads if Congress so provides); the constitutional foundation of the entire PAS system
• 5 U.S.C. §§ 5312–5318 — Executive Schedule pay levels I–V; defines which positions carry which executive pay levels and confirmation requirements
• 5 U.S.C. § 3132 — Senior Executive Service; establishes the SES system created by the Civil Service Reform Act of 1978 including the non-career SES component (up to 10% of SES positions)
• 5 C.F.R. § 213.3301 — Schedule C excepted service; authorizes positions of confidential or policy-determining character that are exempt from competitive service examination
• 5 U.S.C. § 3345 — Vacancies Reform Act of 1998; governs who may perform the functions of vacant Senate-confirmed positions and for how long

Key Mechanics

The presidential appointments system places approximately 4,000 political positions at the top of a career federal workforce of ~2.1 million. Four tiers: (1) PAS (Presidentially Appointed, Senate-Confirmed) — ~1,200 positions including all Cabinet secretaries, agency heads, ambassadors, U.S. attorneys, and independent board members; require FBI background investigation, OPM financial disclosure, and Senate committee hearing and vote; average confirmation time has grown from ~90 days (Reagan) to over 250 days in recent administrations; (2) PA (Presidential Appointment without Senate confirmation) — ~400 positions including White House staff (Chief of Staff, NSC Advisor, Counsel to the President); (3) Non-career SES — ~700 positions (up to 10% of SES); senior management posts fillable by political appointees without Senate confirmation; (4) Schedule C — ~1,500 positions at GS-15 and below of "confidential or policy-determining character"; political staff (special assistants, speechwriters, political liaisons) fillable without confirmation or OGE financial disclosure. All ~4,000 positions are documented in the "Plum Book" (United States Government Policy and Supporting Positions), published by OPM and House Oversight after each election. The Vacancies Reform Act governs who may perform the functions of a vacant PAS position pending confirmation — typically the first assistant to the position or a senior official designated by the President, for a limited time period.

The Four Tiers of Political Appointment

Tier 1 — Presidentially Appointed, Senate-Confirmed (PAS): The roughly 1,200 PAS positions are the constitutional and operational core of presidential personnel authority. They include all Cabinet secretaries, deputy secretaries, under secretaries, assistant secretaries, agency heads, ambassadors, U.S. attorneys, U.S. marshals, federal judges (lifetime), and members of independent boards and commissions. PAS positions require FBI background investigation, OPM financial disclosure review, and Senate committee hearing and vote. The average time from nomination to confirmation has grown from about 90 days under Reagan to over 250 days in recent administrations — a chronic bottleneck that leaves agencies under-resourced at senior levels for years into a presidential term.

Tier 2 — Presidential Appointments Without Senate Confirmation (PA): A smaller category of positions appointable by the President alone, without Senate confirmation. These are typically White House staff (Chief of Staff, National Security Advisor, Counsel to the President), some ambassadors-at-large, and various advisory committee members. These positions fill faster than PAS because they require no Senate action.

Tier 3 — Non-Career Senior Executive Service (NC-SES): The SES was created by the Civil Service Reform Act of 1978 as the government's senior management corps. The non-career SES (up to 10% of SES positions, approximately 700 slots) allows political appointees to serve in senior career positions without Senate confirmation. NC-SES members can be removed by agency heads more easily than career SES (though still with due process requirements), and they serve at the discretion of the agency head within the political structure.

Tier 4 — Schedule C (Excepted Service, Confidential/Policy-Determining): Approximately 1,500 Schedule C positions are at GS-15 and below, covering positions that are "of a confidential or policy-determining character" (5 C.F.R. § 213.3301). These are the political staff throughout agencies — special assistants, speechwriters, political liaisons, chiefs of staff at the bureau level. Schedule C appointments require no Senate confirmation and no OGE financial disclosure; they are filled quickly and turn over entirely with each administration.

The Vetting Process

For PAS positions, the appointment process involves:

1. White House Personnel Office (WHPO) selects and nominates candidates, coordinating with the relevant agency and political liaisons.
2. FBI background investigation — a full-field background check that can take weeks to months, verifying personal history, financial records, foreign contacts, and character references; security clearance adjudication follows.
3. Office of Government Ethics (OGE) financial disclosure review — a nominee must file a public SF-278 financial disclosure identifying assets, income, liabilities, and outside positions; OGE reviews for conflicts of interest and requires recusal agreements or divestitures as conditions of confirmation.
4. Senate committee hearing — the relevant committee holds a public confirmation hearing at which the nominee testifies and answers written questions for the record (QFRs); the committee then votes to report or hold the nomination.
5. Full Senate floor vote — after committee action, the nomination goes to the Senate floor; controversial nominees may face a cloture vote requiring 60 votes (though the "nuclear option" invoked in 2013/2017 eliminated the 60-vote threshold for most nominations, leaving a simple majority requirement for executive branch and judicial nominations below the Supreme Court).

The Plum Book

The Plum Book (formally GPO Publication number Y 3.2:P 75/year) is published within weeks of each presidential election and lists every PAS, PA, NC-SES, and Schedule C position in the federal government. It is the authoritative public guide to the scope of presidential appointment authority. The 2024 Plum Book listed approximately 9,000 positions total across all categories (including boards, commissions, and part-time positions). It is available on GPO Access and has been digitized for each election cycle since 1988.

The Confirmation Bottleneck

The confirmation bottleneck — hundreds of vacant PAS positions at any given time in an administration — is one of the most persistent and consequential structural problems in federal executive management. Causes include: (1) the FBI and OGE vetting timelines, which are largely fixed; (2) Senate floor scheduling, which has become increasingly politicized; (3) individual senators' holds, which can delay nominations indefinitely without a floor vote; (4) the expanded scope of Senate-confirmed positions over time (Congress has added positions faster than it has removed them). The result is that agencies frequently operate for years with career civil servants or Senate-confirmed holdovers in acting capacities — structurally limiting political direction.

Schedule F and the Career/Political Boundary

The Civil Service Reform Act of 1978 established merit principles protecting career civil servants from removal for political reasons (5 U.S.C. § 2301 et seq.). The Trump administration's 2020 Schedule F executive order sought to reclassify career positions "of a confidential, policy-determining, policy-making, or policy-advocating character" into a new excepted service schedule permitting at-will removal. Biden revoked the order on his first day in office; Trump reinstated it in January 2025. Estimates of affected positions ranged from 50,000 to 100,000 career employees. The legal battles over Schedule F — whether the President has statutory authority to reclassify career positions without congressional action — are among the most consequential federal employment litigation of 2025.

How It Affects You

If you are a citizen or voter: The composition of political appointees determines how aggressively laws are enforced, which regulatory priorities agencies pursue, and how government services are delivered. A Cabinet secretary who disfavors a program can slow-walk implementation, reduce budget requests, and replace career managers who execute it energetically — all without changing a single statute. The appointment bottleneck means agencies often lack confirmed leadership in key policy positions for years.

If you are a business or regulated entity: Regulatory direction is set by political appointees at the assistant secretary and bureau chief levels — positions that typically change with administrations. Understanding who holds key regulatory positions (through the Plum Book and FederalPay.org data) and their policy records is essential for anticipating enforcement and rulemaking direction. For businesses seeking government contracts, grants, or approvals, political appointees control the discretionary decisions that career staff cannot make alone.

If you work at a federal agency: If you are a career civil servant, you report to a chain that eventually reaches a political appointee. Understanding the difference between career and non-career SES, Schedule C, and PAS roles in your agency determines who has civil service protection, who can be transferred to a new position, and who is at-will. Schedule F implementation could affect the job security of career employees in policy-adjacent roles throughout your agency.

If you are a journalist, researcher, or policy analyst: The Plum Book is the definitive mapping of presidential appointment authority. FederalPay.org provides salary and position data for federal employees including SES and Schedule C. OGE's public financial disclosure database (FDsys) contains every PAS nominee's financial holdings. The Partnership for Public Service's "Political Appointee Tracker" maintains real-time data on nomination and confirmation status for each administration — the best source for tracking the appointment bottleneck.

Recent Developments

• 2025 — The Trump administration reinstituted Schedule F, directing agencies to identify and reclassify career employees in policy-adjacent roles; multiple federal employee unions filed suit; preliminary injunctions were issued in some circuits while others permitted implementation; the fate of Schedule F remained contested as of mid-2025.
• 2025 — Several PAS nominees for national security, financial regulatory, and Cabinet positions were confirmed on party-line votes after expedited hearings, raising questions about the depth of Senate scrutiny for nominees with significant financial conflicts or prior controversies.
• 2024 — The 2024 Plum Book reflected an expanded number of Schedule C positions compared to 2020, continuing a trend of broadening political appointment authority relative to the career workforce.
• 2017 — The Trump administration's first term was characterized by the slowest PAS confirmation rate in modern history — at one point only 54 of 558 key positions had confirmed nominees — leaving career actings in place for much of the first two years.
• 1978 — The Civil Service Reform Act created the SES framework and codified merit system protections, establishing the current architecture that Schedule F is designed to partially dismantle.
