More than 900 students received offers of college places from the CAO this morning.
Among the 922 offers that were made are 485 applicants who are receiving an offer as a result of upgraded calculated grades results received from the Department of Education.
The department said 422 Level 8 offers and 75 Level 7/6 offers were made to these applicants.
The other 401 successful applicants in this round were receiving an offer for a course through the 'Available Places' facility, or because they were next on the waiting list for a place on a course higher up on their preference list.
Of this last category, 267 received a Level 8 offer and 158 received a Level 7/6 offer.
Applicants receiving an offer in this round have until 3pm next Tuesday to accept, if they wish to do so.
Students received their offers at 10am.
Some but not all of the 485 places are newly created ones.
They are among 6,100 students whose Leaving Cert grades were revised upwards at the weekend after mistakes in the calculated grades system were corrected.
Today's improved offers to those students may benefit others.
As those students move to take up a new place on a college course, many will be vacating places in other programmes, which are likely in turn to become available to other students who may want them.
RTÉ News understands that a significant proportion of the new places created are in areas such as teaching and nursing.
