How to write the AP Gov argument essay
By the CollegePrepRoom editorial team · Updated · How we write and check these pages
The argument essay is the fourth and final free-response question on the AP U.S. Government and Politics exam. The prompt poses a question about a political principle, institution or process, such as whether a large republic best protects liberty, and lists several foundational documents. You take a position and defend it using evidence from at least one of the listed documents and from your knowledge of the course.
This is the only free-response question that requires a thesis and a line of reasoning. It also rewards a specific move that many students skip: responding to an opposing or alternative perspective. This guide covers the 6-point rubric, how to use foundational documents as evidence, how to write the reasoning and rebuttal points, and examples at different levels.

How the argument essay is scored
The argument essay is scored out of 6 points. Each row of the rubric is scored separately, so you can earn points in one row even if you miss another.
| Rubric row | Points | What earns the points |
|---|---|---|
| Claim / thesis | 1 | A defensible claim or thesis that responds to the prompt and establishes a line of reasoning. |
| Evidence | 3 | 1 point for describing one piece of evidence accurately linked to the topic. 2 points for using one piece of specific and relevant evidence from one of the listed foundational documents to support the claim. 3 points for using two pieces of specific and relevant evidence to support the claim, one from a listed foundational document and a second from another foundational document or from course concepts. |
| Reasoning | 1 | Explaining how or why the evidence supports the claim or thesis. |
| Alternative perspective | 1 | Responding to an opposing or alternative perspective using refutation, concession or rebuttal. |
| Total | 6 | Points from all rows are added together. |
- Evidence must be specific. 'Federalist No. 10 talks about factions' describes the document; explaining Madison's argument that a large republic makes it harder for a single faction to form a majority and oppress others uses it as evidence.
- The reasoning point is about explanation: say why the evidence supports the claim. This is often a sentence that begins with because or this shows.
- The alternative perspective point requires engaging with a real opposing view and answering it.

Step-by-step method
Read the prompt and the document list
Identify the question and the listed foundational documents. Choose the document you know best that connects to the question. The course's foundational documents include the Declaration of Independence, the Articles of Confederation, the Constitution, Federalist Nos. 10, 51, 70 and 78, Brutus No. 1 and the Letter from Birmingham Jail.
Take a position you can support with two pieces of evidence
Before committing, check that you can name one specific idea from a listed document and a second piece of evidence from another document or course concept. Choose the side you can support most specifically.
Write a thesis with reasons
State your claim and preview the reasons. For example: 'A large republic best protects liberty because it multiplies factions, making majority tyranny less likely, and because separated powers let ambition check ambition.'
Use the first piece of evidence from a listed document
In the first body paragraph, describe the document's specific argument and explain how it supports your claim. Name the author and document.
Add a second, different piece of evidence
In the second body paragraph, use another foundational document or a course concept such as a Supreme Court case, a constitutional provision or a political process. Explain how it supports your claim.
Explain the reasoning explicitly
After each piece of evidence, write at least one sentence explaining why it supports the claim. Connect it back to the thesis.
Respond to the opposing perspective
Write a paragraph that states the strongest opposing view, ideally with its own evidence (for example, Brutus No. 1's warning that a large republic cannot represent the people's interests), and respond with refutation, concession or rebuttal.
Conclude briefly
Restate your claim in light of the opposing view. Keep the conclusion short; the points are earned in the body.
Common mistakes
Not using a listed document
The second and third evidence points require evidence from one of the documents listed in the prompt. Using only other documents limits the score.
Describing evidence without using it
Summarizing a document's content without connecting it to your claim earns at most the first evidence point.
A thesis without reasons
'A large republic protects liberty' needs reasons to establish a line of reasoning.
A one-sentence rebuttal
A dismissal such as 'Some people disagree, but they are wrong' earns no credit. Answer the reasoning of the other side.
Mixing up Federalist papers
Confusing Federalist No. 10 (factions) with No. 51 (checks and balances) or No. 70 (a single executive) is common. Learn the main argument of each.
Running out of time
The argument essay needs about 40 minutes. Keep the first three questions to about 20 minutes each.
Example: thesis, evidence and rebuttal
Invented prompt for illustration: develop an argument about whether the federal judiciary should have the power to strike down laws passed by elected officials. Use at least one of the following: Federalist No. 78, the U.S. Constitution, Brutus No. 1.
Does not earn the thesis point
The federal judiciary is an important part of the government.
Earns the thesis point
The federal judiciary should have the power to strike down laws because judges with life tenure can protect the Constitution from temporary majorities, and because judicial review lets the courts check the other branches.
Evidence from a listed document
In Federalist No. 78, Hamilton argues that the judiciary is the least dangerous branch because it has neither the sword nor the purse, and that life tenure frees judges to uphold the Constitution against laws that violate it. This supports the claim because a branch without force or money can only act by judgment, so its power to strike down laws is limited.
Response to an alternative perspective
Brutus No. 1 warns that unelected federal judges could expand national power beyond what the people intended. That concern is real, but Marbury v. Madison shows the Court using judicial review to limit itself as well as Congress, and the amendment process remains available to the people if the Court misreads the Constitution.

Practice prompts
Original prompts in the style of the argument essay, written by our editorial team for practice. They are not official exam questions.
- Develop an argument about whether a large republic or small, local governments better protect citizens' liberty. Use Federalist No. 10, Brutus No. 1 or the U.S. Constitution.
- Develop an argument about whether the presidency has become too powerful. Use Federalist No. 70, Federalist No. 51 or the U.S. Constitution.
- Develop an argument about the most effective way for citizens to bring about political change. Use the Letter from Birmingham Jail, the First Amendment or Federalist No. 10.
- Develop an argument about whether the national government or the states should have the main responsibility for education policy. Use the U.S. Constitution, Brutus No. 1 or Federalist No. 51.
How to practice the argument essay
For each foundational document, write three lines: the author and date, the main argument in one sentence, and two positions in the course it could support. Practice by pairing documents on opposite sides, such as Federalist No. 10 and Brutus No. 1.
Write timed argument essays and check them against the four rubric rows. Most students find that the alternative perspective point is the one they skip under time, so plan for it from the start.
