The Government is under pressure to name a date for the proposed referendum on children's rights.
The call - from the Children's Rights Alliance - comes on the 18th anniversary of Ireland ratifying the UN convention on the Rights of the Child.
According to the Alliance, over 65,000 Irish children live in poverty, while one child in three from disadvantaged communities leaves school with literacy problems.
"All parties have committed to having a referendum," said Alliance CEO Jillian van Turnhout.
"Wording has been produced and now we wait (on) the Cabinet to take a decision.
"We say the time is right, the people of Ireland wish to speak on this issue - so give us a referendum and allow us to strengthen children's rights in the Irish constitution."
