The president of the University of Limerick has said there may not be places at the university for all of the students affected by errors in Leaving Certificate results.
Speaking on RTÉ's This Week, Professor Kerstin Mey said while every effort will be made to accommodate additional students on their programmes, "it may not be possible to accommodate everyone".
Professor David FitzPatrick, Technological University Dublin President, said students seeking courses which have mandatory placements, including in the health and education sectors, will face the most challenges.
He said dialogue is urgently required with providers of work placements to see what can be achieved for those students.
However, he said his university in conjunction with the Department of Higher and Further Education would make every effort to ensure that students are accommodated on courses of their choice "as fully as possible".
Yesterday, it was revealed that a total of 6,100 students were due to get improved marks following a review of the Leaving Certificate calculated grades system.
A review found a third error in the coding used to standardise results, in addition to two mistakes discovered last week.
All Leaving Cert 2020 students were informed yesterday evening whether or not they have been affected.
There are concerns over what the impact will be on CAO college offers, and how many students may have lost out on college places because they were competing with others who received results that were incorrectly inflated.
Meanwhile, Minister for Public Expenditure and Reform Michael McGrath has said the Government will examine the contract entered into with the company linked with errors in the Leaving Cert results to determine if action can be taken in relation to costs incurred because of the errors.
Asked whether the company which designed the software would be asked to make a contribution towards the additional costs which have been incurred because of the errors Minister Michael McGrath said: "It would be appropriate for the contract that was entered into by the Department of Education with the Third Party Company to be very carefully examined now to see what recourse may be open to the taxpayer in relation to the consequences of what has happened."
