How the CAO Points System Really Works
Your son sits down at the kitchen table with his mock results and asks whether he has enough points for his course. You want to give him a straight answer, but the more you read online, the less certain you feel. The points system sounds simple until it doesn't. Here is what is actually happening.
How the points are counted
The CAO takes the best six subjects from a single sitting of the Leaving Certificate. That last part matters. Results from two different years cannot be mixed together to build a stronger combination — it is one sitting or the other, whichever produces the higher total. Each grade in each subject converts to a points value, with higher level papers worth more than ordinary level for the same grade. The maximum from six subjects is capped, so there is a ceiling your child cannot go above no matter how many subjects they sit.
There is one deliberate exception to that ceiling. A student who passes higher level maths at a qualifying grade receives bonus points on top of whatever the subject already earned. Those bonus points are added after the six-subject total is calculated, which means they can push a student above what would otherwise be the cap. Check the CAO website for the current bonus threshold and value, because these details are worth confirming each cycle.
Why the cut-off points move every year
This is the part that catches a lot of parents off guard. There is no fixed points score that gets you into any course. The number you see quoted — say, for nursing or engineering — is simply the score of the last applicant who received an offer in that round the previous year. It is set entirely by demand.
If more students apply for a course this year, or if grades across the country are higher, the cut-off rises. If fewer apply, it falls. The college does not set a pass mark for entry. It fills its available places in descending points order until the places run out, and whatever score the final successful applicant held becomes the figure that gets published and whispered about. That number is a snapshot of last year's competition, not a promise about this year's.
The requirements that sit underneath the points
Points get your child into the queue. Matriculation and subject requirements determine whether they are allowed to stand in it at all. These are separate conditions set by individual colleges and courses, and they vary — sometimes quite a lot — between institutions offering what looks like the same course.
Common requirements include:
- A minimum grade in a specific subject, such as a pass or merit in higher level Irish, English, maths or a science
- A language requirement, often with a distinction between higher and ordinary level
- Having taken a particular subject at all, regardless of grade
A student can have the points and still be ruled out because they sat ordinary level maths when the course required higher, or because they did not take a laboratory science. The place to check each course's exact entry requirements is the college's own prospectus or admissions page, not a third-party summary. Requirements listed on aggregator sites are not always up to date.
When two applicants have exactly the same score
It happens more often than you might expect, especially near the cut-off. When two applicants are tied on points and there is only one place left, the CAO does not look at which subject the points came from, or whether one student got there through higher level maths. It does not compare personal statements, because there are none in the Irish system. It uses random selection. A computer draw determines who gets the offer. There is no appeal on the grounds of being unlucky in a draw, though a student can of course take up a place on a lower preference or consider the next round of offers.
This is not a flaw in the system so much as an honest acknowledgement that at absolute parity, no academic distinction exists between the applicants. It is cold comfort if your child is the one who loses the draw, but it is how it works.
The most useful thing you can do next
Sit down with your son or daughter's subject list and look up the matriculation requirements for every course in their CAO order of preference — not just the points from last year, but the specific subject and grade conditions. Do this on each college's own admissions page. It takes an hour and it will tell you far more than the points table alone ever could, because a course your child cannot meet the requirements for should not be on the list at all, regardless of whether their points would reach it.
