The state legislature method of amendment ratification involves the proposed amendment being approved by a specified majority in both houses of the state legislature. In contrast, the state convention method requires the amendment to be ratified by a convention specifically called for that purpose, where delegates discuss and vote on the proposed changes. This latter method can provide a more direct form of public representation, while the former relies on the existing legislative structure. Each method reflects different approaches to involving citizens in the constitutional amendment process.
Every Amendment to the U. S. Constitution to date has been proposed by the method of two thirds of each house of Congress approving the proposal before it goes to the states for ratification. Also, two-thirds of the states can hold conventions to propose amendments
No branch, but the constitution itself does this.

The most common method to add an amendment to the U.S. Constitution is through a two-thirds majority vote in both the House of Representatives and the Senate, followed by ratification from three-fourths of the state legislatures. The least used method involves a constitutional convention called by two-thirds of state legislatures, where an amendment can be proposed and then sent to the states for ratification. This method has never been successfully used to amend the Constitution.
