What is a constitutional amendment?

A constitutional amendment alters the Constitution of the United States by striking or inserting new language. The Constitution establishes the structure, powers, and responsibilities of the federal government. It has been formally amended 27 times.

The constitutional amendment process is as follows:

Step 1

Two-thirds vote

An amendment may be proposed by a two-thirds vote in both the House of Representatives and the Senate or by a constitutional convention called by two-thirds of state legislatures.

Step 2

Three-fourths ratification

Once proposed, the archivist of the United States submits the amendment to the states for consideration. It becomes part of the Constitution once it is ratified by three-fourths of the states.
