Around 14,500 Ukrainian children are now enrolled in Irish schools, the Oireachtas Education Committee has heard.
Over 9,000 of those pupils are at primary level while more than 5,000 are at post-primary level.
The figures were provided by officials in the Department of Education, who were appearing before the Oireachtas Education Committee.
Commenting on the figures, Hubert Loftus, an Assistant Secretary at the Department, told members that it was "hugely positive" and "a great achievement for the school system".
Responding to questions from Fine Gael Senator Aisling Dolan, he said that the intake of new students was done in a "very inclusive and integrated way that supports the children and supports their wellbeing given all they've been through".
Separately, Mr Loftus told Sinn Féin's Education spokesperson Donnchadh Ó Laoghaire that around 1,000 Ukrainian children are in 6th class and would be moving into the post-primary system after the summer holidays.
Mr Ó Laoghaire had been asking officials about the Department's preparations in terms of demographic pressures, given a current rise in the school-going population.
He was told that the school community was already seeing a "demographic bulge" that was likely to "peak" in the next "year or two".
