Your child will then be placed on a list in order of merit for each course that they are eligible for e.g., if your child has the highest points score he/she goes to the top of the list and the child with the second-highest points score goes second on the list, and so on.
The HEI then instructs CAO on how many offers to make for each course. If your child was in 20th position for a chosen course, and the institution instructs CAO to offer 25 places, then your child will receive an offer of a place on that course (unless they have received an offer of a course higher up on their preference list). The points score of the applicant in 25th place will be published as the cut-off points for that course in that round.
