The Constitution can be amended, or changed, in a couple of ways.
First, when Congress thinks a change is needed, they can propose an amendment. To do this, two-thirds of both the House of Representatives and the Senate must agree on it.
Second, if enough states want a change, two-thirds of state legislatures can call for a special convention to suggest amendments.
Once an amendment is proposed, it must be approved by three-fourths of the states—either through their legislatures or by special state conventions—before it can become part of the Constitution.
So, it’s a pretty big deal! It takes a lot of agreement from different parts of the government and the states to make a change.
