The Government has confirmed the full list of Ministers of State, with eight from Fianna Fáil, seven from Fine Gael and three Green Party TDs.
The Fianna Fáil, Fine Gael and Green Party leaders consulted before the list of junior ministers was finalised, to ensure there was a geographical balance.
The appointments were not met with universal approval.
Fianna Fáil TD for Cork North West Michael Moynihan expressed his extreme disappointment at not being appointed a junior minister by Taoiseach Micheál Martin.
"He has insulted me and my community. I have worked so hard for the party over the last nine years; took a lot of s*** for him. Very, very cross," he said.
Former Minister for Education Joe McHugh and Fianna Fáil TD Jim O'Callaghan confirmed they had declined offers of ministerial posts.
Mr O'Callaghan said he wanted "to devote more time to strengthening our great party by making it a more attractive option for young voters".
Mr O'Callaghan said he was asked this afternoon by Mr Martin to accept an appointment as a Minister of State in the Government.
However, having thought carefully about the offer he decided not to accept, he said.
"The reason I am not accepting is because I believe my energy and abilities will be better used as a backbench Fianna Fáil TD rather than as a junior member of government," the Dublin Bay South TD said.
"At a time when many of our party's senior members will be preoccupied with their ministerial duties, I want to devote more time to strengthening our great party by making it a more attractive option for young voters," he added.
Mr O'Callaghan said Fianna Fáil needs strong voices outside Government who can ensure that the party's identity can be protected during the term of this coalition Government.
