Constitution Day: Why September 17 Matters on the Civics Test

Constitution Day is September 17 — the anniversary of the day delegates signed the U.S. Constitution in Philadelphia in 1787. That date is more than a calendar note for people studying for citizenship: it points straight at one of the most important answers on the civics test.
The founding document written in 1787
On the 2025 Naturalization Civics Test, you may be asked: What founding document was written in 1787? The accepted answer is the (U.S.) Constitution (question 82). Remembering 1787 → Constitution is one of the clearest date-to-document links in the whole test bank.
The Constitution opens with “We the People.” Those words mean self-government — the idea that the people of the United States establish the government and give it its power. The Constitution is also the supreme law of the land: it sets up the national government, defines how power is shared and limited, and protects basic rights. Changes to the Constitution are made through amendments (today there are twenty-seven).
Constitutional Convention, Madison, and the Federalist Papers
Delegates met at the Constitutional Convention in Philadelphia to write a new plan of government. James Madison is often called the “Father of the Constitution” for his role in shaping it; he later became the fourth president of the United States and was one of the writers of the Federalist Papers.
The Federalist Papers supported passage of the Constitution. On the civics test, accepted writers include (James) Madison, (Alexander) Hamilton, (John) Jay, and Publius (the pen name they used). Why were the Federalist Papers important? They helped people understand the Constitution and supported passing it.
George Washington is also tied to this story on the test: he served as President of the Constitutional Convention (among other famous roles).
Your civics test has not changed
The 2025 Naturalization Civics Test is unchanged: a 128-question bank; 20 questions asked at the interview; 12 correct to pass, for Form N-400 applications filed on or after October 20, 2025. Constitution Day is a good moment to review founding-document questions — not a signal that USCIS has rewritten the test.

Tip for test day: if you see 1787, answer (U.S.) Constitution. If you see Federalist Papers, think Madison, Hamilton, Jay (Publius) — and that they helped people understand and support the Constitution.
