Congress must call a convention for proposing amendments upon application of the legislatures of two-thirds of the states (i.e., 34 of 50 states). Amendments proposed by Congress or convention become valid only when ratified by the legislatures of, or conventions in, three-fourths of the states (i.e., 38 of 50 states).

What are the two ways to amend?

Article V of the Constitution provides two ways to propose amendments to the document.
