More than 140 people have registered to run for 45 seats in next year's constitutional convention in the Marshall Islands.
Many of the Republic's 33 MPs will be competing with members of the public for seats in a February election, while 24 chiefs will contest 12 seats reserved for traditional leaders.
Our correspondent Giff Johnson said the most high-profile proposed amendment was a change from a parliamentary to a presidential system of government.
But he said it's a long process for amendments to get the go-ahead.
"The parliament has to put amendments on the table, then the Con-Con itself has to review those and adopt change, and then they have to get put out to the public for approval. So there's a long way to go still to see what will actually come out from the Con-Con," said Giff Johnson.
Mr Johnson said the public has voted against all substantive proposed amendments in previous constitutional conventions.
