Up to 450 new CAO offers will be made after the Leaving Cert calculated grades computer coding debacle.
The figure covers offers at both Level 8 (honours degree) and Level 7/6, and up to one in four will be for places in Technological University Dublin.
The Central Applications Office (CAO) will issue the offers to Leaving Cert 2020 candidates on Thursday, in tandem with other Round 4 offers.
Full details of the places will not be known until then, but there are quite a number for teaching-related courses.
On the other hand, it is understood the upgrades will not lead to a surge of offers for medicine.
The maximum number of new offers for any single course will not be more than eight to 10.
Colleges are working through their capacity to make offers for the current year, but it is understood the scale of the offering - less than half the potential 1,000 mentioned last week - has not caused alarm.
Higher Education Minister Simon Harris tweeted yesterday that he was meeting the Higher Education Authority (HEA) at lunchtime.
The HEA is writing to colleges and asking them to advise if there are any particular difficulties.
The pattern of expected offers reflects reports that many upgrades were in the middle space rather than at the upper end from H2 to H1.
Around 6,100 students have been advised that a grade in one or more subjects has increased after corrections were made to the algorithm that processed the results.
Not all upgrades boost points to the extent that a student becomes entitled to a higher CAO offer.
Around 1,000 of those students who have received an upgrade were not CAO applicants.
The Department of Education said 7,900 calculated grades were higher than they should have been.
