Accurate CAO Points Calculator for the Leaving Certificate

Navigating the transition from secondary school to third-level education in Ireland can feel overwhelming, especially when college offers depend heavily on your final exam results. Our CAO Points Calculator is designed to take the guesswork out of the process. Whether you are aiming for a Level 8 Honours Degree at a university or a Level 6/7 course at a Technological University (TU), this tool instantly and accurately translates your predicted or actual Leaving Certificate grades into CAO points.

We built this calculator directly aligned with the official Central Applications Office (CAO) and State Examinations Commission (SEC) guidelines for 2026. It automatically factors in the complex rules—like the best six subjects and specific bonus points—so you can focus on your studies instead of manual math.

How the Leaving Cert Grading System Works

The Irish grading system categorizes marks into bands, rewarding points based on the level of the paper you sit: Higher Level (HL) or Ordinary Level (OL). Foundation Level subjects are generally not counted for standard CAO points by most Higher Education Institutions (HEIs), though there are rare exceptions for Foundation Maths in specific courses.

Here is the standard points breakdown you need to know:

  • Grade 1 (90% - 100%): Higher (H1) = 100 points | Ordinary (O1) = 56 points
  • Grade 2 (80% - 89%): Higher (H2) = 88 points | Ordinary (O2) = 46 points
  • Grade 3 (70% - 79%): Higher (H3) = 77 points | Ordinary (O3) = 37 points
  • Grade 4 (60% - 69%): Higher (H4) = 66 points | Ordinary (O4) = 28 points
  • Grade 5 (50% - 59%): Higher (H5) = 56 points | Ordinary (O5) = 20 points
  • Grade 6 (40% - 49%): Higher (H6) = 46 points | Ordinary (O6) = 12 points
  • Grade 7 (30% - 39%): Higher (H7) = 37 points | Ordinary (O7) = 0 points
  • Grade 8 (0% - 29%): Higher (H8) = 0 points | Ordinary (O8) = 0 points

Understanding the "Best 6 Subjects" Rule

One of the most common mistakes students make is adding up the points for every single subject they study. The CAO system strictly calculates your final score based exclusively on your top six subjects achieved in a single sitting of the Leaving Certificate.

Most Irish students sit for seven or eight subjects. When you enter your grades into our calculator, the algorithm automatically identifies all your scores, ranks them from highest to lowest, and discards the lowest-performing subjects. Only the six highest point values are combined to generate your maximum CAO score.

The 25-Point Higher Level Mathematics Bonus

To encourage students to pursue Science, Technology, Engineering, and Mathematics (STEM) fields, the Irish government introduced a bonus points initiative for Higher Level Maths. This can significantly boost your overall CAO points, but strict criteria apply.

You are awarded an extra 25 bonus points if you achieve a grade of H6 or above (a score of 40% or higher) in Higher Level Mathematics. If you score an H7 (30-39%) or an H8 (below 30%), no bonus points are awarded. When calculating your final score, our tool first adds these 25 points to your Maths score. Then, it checks if this newly boosted Maths score makes it into your top six subjects. If it does, the bonus is included in your total. If your Maths score (even with the bonus) is still lower than your 6th best subject, it will not be counted.

How LCVP Link Modules Affect Your Points

If you are taking the Leaving Certificate Vocational Programme (LCVP), your Link Modules can be a great way to secure extra points. LCVP is not graded on the standard H1-H8/O1-O8 scale. Instead, it is graded in three categories:

  • Distinction (80% - 100%): 66 CAO Points (Equivalent to an H4 or a high O1)
  • Merit (65% - 79%): 46 CAO Points (Equivalent to an H6 or O2)
  • Pass (50% - 64%): 28 CAO Points (Equivalent to an O4)

Your LCVP score can be used as a valid substitution for one of your core subjects if it yields a higher point value. For example, if your 6th best regular subject is an O3 (37 points) but you scored a Merit in LCVP (46 points), the CAO (and our calculator) will automatically drop the O3 and count the LCVP Merit instead, raising your total score.

Matriculation Requirements vs. CAO Points

While our Leaving Cert points calculator helps you determine your numerical score, it is vital to remember that points alone do not guarantee college admission. Every course in Ireland has Minimum Entry Requirements (Matriculation).

For instance, a Level 8 Engineering degree might require 450 CAO points, but it might also mandate a minimum of an H4 in Higher Level Maths. Even if you score 600 points overall, if you only achieve an H5 in Maths, you will not receive a Round 1 offer for that specific course. Always check the specific subject requirements on the college website or the official CAO handbook alongside calculating your total points.

Leaving Cert & CAO Frequently Asked Questions

What are the maximum CAO points you can get?
The absolute maximum CAO points a student can achieve is 625. This is accomplished by scoring an H1 (100 points) in six subjects (totaling 600 points) and qualifying for the 25 bonus points by taking Higher Level Mathematics.
Do I lose points if I fail a subject?
Scoring an H8 or O8 (0-29%) means you earn 0 points for that specific subject. While you don't mathematically "lose" points from your total, that subject will contribute nothing to your score. If it was one of your 6 main subjects, it severely limits your maximum possible total. Furthermore, failing core subjects like Maths or English might cause you to miss the basic matriculation requirements for many college courses.
Can I combine points from two different Leaving Cert years?
No. For the purpose of calculating CAO points, all points must be achieved in a single sitting of the Leaving Certificate. However, if you repeat the Leaving Cert to get higher points, you can use the total points from your best year. Note that you can combine different years to meet basic matriculation subject requirements (e.g., passing English one year and Maths the next), but the points themselves cannot be merged.
Are Foundation Level subjects counted for CAO points?
As a general rule, the vast majority of Higher Education Institutions (HEIs) in Ireland do not award CAO points for Foundation Level subjects. There are a few rare exceptions where certain Institutes of Technology or TUs might offer 20 points for Foundation Maths (Grade F1/F2) for specific courses, but standard calculations rely strictly on Higher Level (HL), Ordinary Level (OL), and LCVP.
How do random selection offers work if I meet the points?
Sometimes, multiple students achieve the exact cut-off points required for the last remaining places in a course (e.g., a course requires 450 points, and five students have exactly 450 points, but there is only one seat left). In this scenario, the CAO system uses a random number generation process to select the student. You will see an asterisk (*) next to the points in the CAO offers list when random selection was used.
Do I get bonus points for studying through Irish?
The CAO system itself does not award bonus points for taking exams in Irish. However, some specific universities, such as University of Galway (OÉ Gaillimh), offer additional points for certain courses if you sat your exams through Irish and meet their specific language criteria. This is managed by the university, not the standard CAO calculator.
