Recognition
How Ireland Recognizes the IB Diploma
The International Baccalaureate (IB) Diploma is accepted as equivalent to the Irish Leaving Certificate for admission to Irish higher education institutions. IB scores are converted to CAO points using an official conversion table published annually in the CAO Entry Requirements document.
The IB Diploma qualifies holders for entry into Level 6 (Higher Certificate), Level 7 (Ordinary Degree), and Level 8 (Honours Degree) courses through the CAO. A minimum IB score of 24 points is generally required, though individual programmes may require higher scores.
Additionally, applicants who achieve a grade of 4 or above in IB Higher Level Mathematics are awarded 25 bonus points, provided Mathematics is included in the overall award used for points calculation.
Equivalence
Do IB Students Need an Irish Leaving Certificate?
No — the IB Diploma is accepted as a standalone qualification
The IB Diploma is recognized as equivalent to the Irish Leaving Certificate for CAO application purposes. You do not need to obtain a separate Irish qualification or undergo a formal credential evaluation process. Your IB results are converted directly to CAO points.
Subject-specific requirements: Some programmes require specific subjects at certain levels. For example, Engineering programmes typically require Higher Level Mathematics, and Science programmes may require specific science subjects. Always check the individual programme requirements on the CAO or institution website.
