Proposal:
There are two ways to propose an amendment to the Constitution.
Article V gives Congress and an Amendments Convention exactly the same power to propose amendments, no more and no less.
Disposal:
Once Congress, or an Amendments Convention, proposes amendments, Congress must decide whether the states will ratify by the:
The State Ratifying Convention Method has only been used twice: once to ratify the Constitution, and once to ratify the 21st Amendment repealing Prohibition.
Ratification:
Depending upon which ratification method is chosen by Congress, either the state legislatures vote up-or-down on the proposed amendment, or the voters elect a state ratifying convention to vote up-or-down. If three-quarters of the states vote to ratify, the amendment becomes part of the Constitution.
I have two reference works for those reading this thread.
The first is from the American Legislative Exchange Council, a conservative pro-business group. This document has been sent to every state legislator in the country.

The second is a 1973 report from the American Bar Association attempting to identify gray areas in the amendatory process to include an Amendments Convention. It represents the view of the ruling class of 40 years ago. While I don't like some of their conclusions, they have laid out the precedents that may justify those conclusions. What I respect is the comprehensive job they did in locating all the gray areas. They went so far as to identify a gray area that didn't pop up until the Equal Rights Amendment crashed and burned a decade later. Even if you find yourself in disagreement with their vision, it's worth reading to see how the ruling class will try to dominate an Amendments Convention.
Report of the ABA Special Constitutional Convention Study Committee
“It represents the view of the ruling class of 40 years ago.”
That’s another amendment: every change made in the last 40 years is null and void.
That includes every change in everything.
Who gets to decide these issues, the courts, the Congress, the state legislatures?
I know if I ask you I am likely to get an informed answer.
