The U.S. Constitution was designed to be strong but not frozen in time. Article V explains how Americans can formally change the Constitution through amendments. This process matters because amendments have expanded rights, changed elections, and adjusted how the government works. It is difficult on purpose so that changes must have broad support across the nation.
The amendment process has two main stages: proposal and ratification. An amendment can be proposed either by a two-thirds vote in both houses of Congress or by a national convention called by two-thirds of the states. To become part of the Constitution, it must then be ratified by three-fourths of the states. This high standard helps make sure amendments reflect more than a temporary political opinion.

Vocabulary
- Amendment
- A formal change or addition to the Constitution.
- Article V
- The part of the Constitution that explains how amendments are proposed and ratified.
- Proposal
- The first stage of the amendment process, when an amendment is officially suggested for approval.
- Ratification
- The formal approval of an amendment by the required number of states.
- Supermajority
- A voting requirement larger than a simple majority, such as two-thirds or three-fourths.
Common Mistakes to Avoid
- Thinking the president must sign a constitutional amendment is wrong because amendments do not go through the normal lawmaking process and do not require presidential approval.
- Confusing proposal with ratification is wrong because proposal only suggests an amendment, while ratification makes it part of the Constitution.
- Assuming a simple majority can amend the Constitution is wrong because Article V requires supermajorities, such as two-thirds and three-fourths.
- Forgetting the role of the states is wrong because three-fourths of the states must ratify an amendment before it becomes valid.
Practice Questions
- 1 In a Senate with 100 members, how many senators are needed to reach the two-thirds vote required to propose an amendment?
- 2 There are 50 states today. How many states must ratify a proposed amendment for it to become part of the Constitution?
- 3 Explain why the framers made the amendment process difficult but still possible. Use one historical example, such as the Bill of Rights, the 13th Amendment, or the 19th Amendment.
