Start with a question

How does the United States Constitution change to meet new challenges and ideas?

In brief

The Constitution can be changed through a formal amendment process that requires approval by both Congress and the states. This ensures changes are carefully considered and widely supported.

Why this matters

The amendment process allows the Constitution to adapt over time while maintaining stability. An amendment can be proposed either by two thirds of both houses of Congress or by a national convention called by two thirds of state legislatures. To become part of the Constitution, the amendment must then be ratified by three fourths of the state legislatures or state conventions. This two-step process balances the need for change with broad agreement, preventing frequent or hasty alterations.

A simple example

For example, the 19th Amendment, which granted women the right to vote, was proposed by Congress in 1919 and ratified by enough states in 1920, demonstrating the amendment process in action.

Questions to think about

  • Why do you think the Constitution requires such a high level of approval to amend it?
  • How might the amendment process protect both change and stability in government?
  • Can you think of any issues today that might be addressed through a constitutional amendment?

Try this
