CAO Points Calculator: How Home-Educated Students Convert A-Levels, IB, and QQI Grades

The CAO points calculator on the CAO and CareersPortal websites is designed for Leaving Certificate students. Enter your predicted grades, press calculate, see your points. For home-educated students sitting A-Levels, the IB Diploma, or QQI Level 5 modules, the process is more involved — and the differences in how points are counted can significantly affect which courses are within reach.

Here is exactly how each framework converts to CAO points.

How CAO Points Work

The CAO (Central Applications Office) ranks applicants by a points score generated from their examination results. Higher points means higher priority for limited course places. The maximum possible score is 625 points across all three recognised frameworks — the Irish Leaving Certificate, GCE A-Levels, and the IB Diploma are mathematically equalised at the top end.

Points are calculated from a maximum of four different subject results. Sitting more than four subjects doesn't add points — only the best four count. There are also 25 bonus points available in all three systems for achieving a passing grade in Mathematics at the appropriate level.

Leaving Certificate Points (for Home Educators Sitting as External Candidates)

Standard Leaving Certificate grades convert to CAO points as follows:

The maximum from six Higher Level H1 grades is 600 points. The 25 bonus points apply if you achieve H6 or above in Higher Level Mathematics.

The average Leaving Certificate points score for successful Level 8 applicants is roughly 400–450 points, though this varies enormously by course. Medicine at UCD or TCD sits around 580+; many arts and social science courses have random selection at 300–350.

The critical warning for home educators: From 2025–2029, the Leaving Certificate is being reformed to include 40% continuous assessment across Biology, Chemistry, Physics, Business, and other subjects. These assessments must be signed off by a registered school teacher and principal. Home-educated external candidates without a cooperating school are mathematically excluded from earning full marks in these subjects — which directly suppresses your achievable points total before the written exams even begin.

A-Level Points Conversion for the CAO

This is the framework most home-educated families in Ireland rely on, because A-Levels are assessed entirely by written terminal examinations — no ongoing coursework authentication is needed.

Ireland does not use the UK UCAS tariff. The CAO uses its own bespoke A-Level conversion:

Points are calculated from the best three A-Level results in a single sitting, plus optionally a fourth A-Level or the best AS-Level result in a single sitting.

Mathematics bonus: 25 bonus points apply for achieving Grade E or above in A-Level Mathematics.

Example calculation: A student achieves A* in Biology (180), A in Chemistry (150), B in Mathematics (130 + 25 bonus), and C in History (115). Total: 180 + 150 + 130 + 25 + 115 = 600 points. This sits at the ceiling alongside six H1 Leaving Certificate grades.

Matriculation note: CAO points alone don't guarantee entry. Each university also requires that applicants present six distinct recognised subjects. For A-Level applicants, this typically means a combination of A-Level and GCSE/IGCSE results — usually two A-Levels at Grade C or above, plus four GCSEs at Grade C (grade 4) or above. Plan subject selection with this six-subject floor in mind from the outset.

IB Diploma Points Conversion

The full IB Diploma (awarded when a student achieves a minimum of 24 overall IB points) is recognised by all Irish universities for Level 8 entry.

Mathematics bonus: 25 bonus points for achieving Grade 4 or above in Higher Level (HL) Mathematics.

The IB Diploma is a strong route for home-educated students who can access a distance-learning IB programme, though providers are limited in Ireland and costs are significant.

QQI Level 5 Points: The Home Educator's Most Strategic Pathway

QQI (Quality and Qualifications Ireland) Level 5 awards work differently from the other frameworks — and for many home-educated students, this is the most accessible university pathway.

A full QQI Level 5 Major Award requires 120 credits, typically eight modules. Each module is graded on a three-tier scale:

To calculate total CAO points: multiply the grade value by the number of modules (up to eight), then scale to the CAO points system. The maximum achievable score — eight Distinctions — generates 390 CAO points.

This is lower than the Leaving Certificate or A-Level maximum, but QQI applicants compete in a separate pool. Major universities — including DCU (up to 10% of places on over 65 courses), UCD, UCC, UG, and the Technological Universities — reserve specific places for QQI applicants. In this reserved pool, QQI applicants only compete against other QQI applicants, not against Leaving Certificate students.

The strategic implication: If a home-educated student achieves eight Distinctions in a QQI Level 5, they have 390 points and access to reserved quotas at major Irish universities. A student who sits the Leaving Certificate as an external candidate under the new 40% continuous assessment regime but cannot get project work authenticated may achieve a similar or lower points score — with no reserved quota access.

LCVP Points (and Why They Don't Apply to Home Educators)

Several parents researching CAO options encounter the Leaving Certificate Vocational Programme (LCVP), which generates up to 66 CAO points for a Distinction in its link modules. The LCVP is school-based, requires validated work experience placement, and relies entirely on school infrastructure for assessment. It is not accessible to independent home educators without a host school. The same applies to the Leaving Certificate Applied (LCA), which doesn't convert to CAO points at all.

Choosing the Right Framework

The decision depends on your child's learning profile, timeline, and target courses:

Choose A-Levels if: your child is a strong self-directed learner, you can access distance learning providers and independent exam centres, you want maximum flexibility in subject choice, and the target courses require competitive points above 400.

Choose QQI Level 5 if: your child benefits from continuous assessment rather than high-stakes terminal exams, you want access to reserved university quotas, or you're targeting courses where the QQI reserved places carry lower effective competition.

Consider the Mature Student route if: your child is willing to wait until age 23, wants to use Open University credits to demonstrate capability, and the target course has mature student quotas.

The Ireland University Admissions Framework provides a full pathway comparison — including module selection strategies for QQI Level 5, the CAO points conversion matrix for all three frameworks, and year-by-year timelines showing when each route needs to start to meet the CAO application deadlines.
