Step-by-step: How an Amendment Becomes Part of the Constitution

The process of amending the United States Constitution involves several steps to ensure that changes are carefully considered and broadly supported. This article outlines the typical procedure for an amendment to become part of the Constitution.

Proposal of the Amendment

The process begins with the proposal of an amendment. This can occur in two ways: either by two-thirds of both the House of Representatives and the Senate approving the amendment, or by a constitutional convention called by two-thirds of the state legislatures. The latter method has never been used.

Ratification Process

Once proposed, the amendment must be ratified by three-fourths of the state legislatures or state conventions. Congress determines which method will be used for ratification. This step ensures that the amendment has widespread support across the states.

Final Certification

After the necessary number of states ratify the amendment, Congress certifies the ratification. The amendment then becomes part of the Constitution and is officially adopted.

Summary of the Process

  • Proposal by two-thirds of Congress or a constitutional convention
  • Ratification by three-fourths of the states
  • Congress certifies the amendment
