6.3 Government Departments & Federal Agencies

Key Takeaways

  • There are 15 Cabinet-level executive departments (State, Treasury, Defense, Justice, Interior, Agriculture, Commerce, Labor, HHS, HUD, Transportation, Energy, Education, Veterans Affairs, Homeland Security); their secretaries are Senate-confirmed and serve at the President's pleasure.
  • Independent agencies (NASA, CIA, EPA, Social Security Administration) sit outside the Cabinet but are still generally removable at will by the President.
  • Independent regulatory commissions (SEC, FCC, FTC, Federal Reserve) have bipartisan, multi-member boards with fixed terms and for-cause removal — the key feature that insulates them from presidential control.
  • Agencies implement law through rule-making — writing specific, legally binding regulations under authority Congress delegates through statute.
  • The Department of Defense adopted the secondary title "Department of War" by executive order in 2025, but its statutory legal name remains Department of Defense unless Congress formally changes it.

Why Federal Departments & Agencies Matter

Congress writes broad laws; the President signs them — but neither body actually issues passports, inspects meatpacking plants, or approves new medications on a daily basis. That day-to-day work belongs to the federal bureaucracy: the network of departments, agencies, and commissions that implement and enforce law. The GED blueprint captures this directly as CG.c.6, "governmental departments and agencies," and it connects to a broader idea tested elsewhere on the exam — that the executive branch is far larger than just the President. Expect GED items that name a real department or agency and ask what it does, or that describe a function ("approves new prescription drugs," "collects federal income tax") and ask which agency performs it.

Core Terms

Bureaucracy refers to the layered administrative structure — organized by hierarchy, specialization, and standardized procedure — that carries out the government's ongoing functions. It is sometimes criticized as slow-moving ("red tape"), but it exists because Congress cannot write a law detailed enough to cover every future circumstance; agencies fill in the details through rule-making (writing specific regulations under authority Congress delegates to them).

The Cabinet is the group of top officials who head the major executive departments and formally advise the President. Cabinet secretaries are nominated by the President and confirmed by the Senate, and they serve at the President's pleasure — meaning the President can remove them at will, unlike judges or many independent-agency officials.

The 15 executive departments (as of the current federal structure) are:

DepartmentCore Function
StateForeign policy, diplomacy, embassies
TreasuryCurrency, federal revenue, IRS
DefenseMilitary forces and national security (informally using the secondary title "Department of War" since a 2025 executive order, though its statutory legal name remains Department of Defense unless Congress formally acts)
JusticeFederal law enforcement, prosecutions (FBI, DOJ)
InteriorPublic lands, national parks, natural resources
AgricultureFarming programs, food safety (USDA)
CommerceTrade, business regulation, Census Bureau
LaborWorkplace standards, employment statistics
Health and Human ServicesPublic health, Medicare/Medicaid, FDA oversight
Housing and Urban DevelopmentHousing policy, urban development
TransportationHighways, aviation, rail safety
EnergyEnergy policy, nuclear weapons stockpile
EducationFederal education policy, student aid
Veterans AffairsVeterans' healthcare and benefits
Homeland SecurityBorder security, disaster response (FEMA), TSA

You do not need to memorize all 15 by rote for the GED, but recognizing the department behind a described function (e.g., "issues passports" → State Department; "administers Social Security" → an independent agency, not a Cabinet department, see below) is a realistic test skill.

Independent Agencies vs. Independent Regulatory Commissions

Not every federal body is a Cabinet department. The GED blueprint's phrase "departments and agencies" deliberately includes both:

  • Independent agencies are single-purpose bodies outside the Cabinet structure, headed by an administrator the President can typically remove at will (like a Cabinet secretary). Examples: NASA (space exploration), CIA (foreign intelligence), EPA (environmental regulation), Social Security Administration (retirement/disability benefits).
  • Independent regulatory commissions are a distinct sub-type with more insulation from presidential control: they are led by a multi-member, bipartisan board whose members serve fixed, staggered terms and can generally only be removed "for cause" (misconduct or neglect of duty), not simply because the President disagrees with their decisions. Examples: Securities and Exchange Commission (SEC) — regulates stock markets and securities fraud; Federal Communications Commission (FCC) — regulates broadcasting and telecommunications; Federal Trade Commission (FTC) — polices unfair business practices and antitrust; Federal Reserve Board — sets monetary policy (see Chapter 15). These commissions exercise quasi-legislative power (writing binding regulations) and quasi-judicial power (holding hearings and issuing enforcement rulings) — a blend the GED sometimes tests by asking what makes an agency "independent" from the President.

Exam Scenario Walkthrough

A GED item might read: "An agency is led by a five-member bipartisan board. Members serve staggered terms and can be removed by the President only for documented misconduct, not policy disagreement. This description best fits which type of federal body?" Applying the terms above, this is the definition of an independent regulatory commission (like the SEC or FCC) — the fixed-term, for-cause-removal structure is the distinguishing feature versus a Cabinet department (removable at will) or a standard independent agency.

Another format presents a short passage about the EPA issuing a new regulation limiting factory emissions and asks what power the agency is exercising — the answer is rule-making authority delegated by Congress (through a statute like the Clean Air Act), not an act of Congress itself.

Common Traps

  1. Confusing Cabinet secretaries with independent agency heads. Both can be removed by the President, but only Cabinet departments go through Senate confirmation as part of the formal Cabinet structure described in Article II.
  2. Assuming all regulators are equally controllable by the President. Independent regulatory commissions (SEC, FCC, FTC) are deliberately insulated via fixed terms and for-cause removal — a distinction the test can probe directly.
  3. Missing that agencies make binding rules, not just recommendations. Regulations issued through the rule-making process carry the force of law once finalized, even though no single agency regulation was individually voted on by Congress.
