Show answer & explanation

Correct answer: D. A two-thirds vote of both houses of Congress

The most common method for proposing an amendment to the U.S. Constitution is a two-thirds vote in both the House of Representatives and the Senate.

Why the other options are wrong

  • A. A national referendum is not a constitutional method for proposing amendments.
  • B. The Supreme Court interprets the Constitution but does not propose amendments.
  • C. This is a method of ratification, not proposal, and requires three-fourths of state legislatures.

Constitutional Amendment Process (Proposal)

The U.S. Constitution can be formally changed through a two-step process of proposal and ratification. The most common proposal method is a two-thirds vote in both the House and Senate.

  • Two methods of proposal, two methods of ratification
  • 2/3 vote in Congress is the primary proposal method
  • No amendment has been proposed by national convention yet

Memory trick: To change the Constitution, Congress proposes, states ratify.
