Students who want breadth across six to eight subjects usually settle into Ireland's Leaving Certificate, while those who prefer depth in three or four areas tend to thrive with A-levels. The Leaving Cert relies almost entirely on terminal written exams, whereas A-levels can include coursework alongside final papers. The sections below unpack grading, timelines and what each route means for university applications.
TL;DR:
- An H1 converts to 36 UCAS tariff points, but competitive UK courses may still require specific subject grades and university equivalence tables.
- For 2026, Leaving Certificate written exams run June 3 to 23, and results arrive August 21 through the Candidate Self Service Portal.
- Students concerned about exam day nerves should ask whether their chosen Leaving Certificate subjects include practical or project components that spread assessment.
- Leaving Certificate results can support UK applications, and A levels can qualify for CAO entry, provided grades meet each course's subject requirements.

Structural differences: subjects, levels and assessment models
The two qualifications ask very different things of a 16 to 18 year old. A typical Leaving Cert student studies six to eight subjects, choosing between Higher, Ordinary and, in some subjects, Foundation level, depending on ability and the demands of their target course. Almost everything rests on written exams taken at the end of two years, with only a handful of subjects carrying a practical or project component built in along the way.
A-level students, by contrast, generally specialise in three or four subjects, occasionally extending to an AS qualification taken alongside or before the full A-level. Most A-levels in England now follow a linear model, with all exams sat at the end of the course, though some subjects retain coursework elements that count towards the final grade. Scotland, Wales and Northern Ireland each run slightly different variants, so it's worth checking the relevant exam board for a specific school.
The practical difference shows up in daily school life. Leaving Cert students spread their attention across a wider timetable, with less room to go deep into any single subject before the state exams arrive. A-level students spend two years building detailed, often university-level knowledge in a narrow set of subjects, with more class time devoted to extended essays, problem sets or lab work tied to those subjects alone.
For families weighing up the two systems, the consequences play out like this:
- Leaving Cert students juggle more subjects at once, which suits generalists but leaves less time per topic.
- A-level students go deeper into fewer areas, which suits those who already know their intended degree subject.
- Coursework carries more weight in several A-level subjects, easing the pressure of a single exam sitting.
- The Leaving Cert's terminal exam structure means two or three weeks in June determine almost the entire grade.
Neither structure is inherently better. A student who enjoys variety and hasn't settled on a specific university course often finds the Leaving Cert's spread reassuring. A student who already wants to study engineering or medicine, and wants to start building that knowledge early, often prefers the focus that A-levels allow.
Grades, points and UCAS tariff: how results translate between systems
Leaving Cert grades run from H1 to H8 at Higher level and O1 to O8 at Ordinary level, with H1 and O1 marking the top band in each. These letter grades then convert into CAO points for Irish university applications, and separately into UCAS tariff points when a student applies to a UK university.
The UCAS Tariff guide sets out the conversion for Leaving Cert grades sitting Higher level papers: an H1 is worth 36 UCAS tariff points, an H2 is worth 30, an H3 is worth 24, an H4 is worth 18, an H5 is worth 12 and an H6 is worth 9, with Ordinary Level grades carrying far fewer points (O1 = 12, O2 = 10, O3 = 8, O4 = 6). This table lets a UK admissions tutor compare an Irish applicant's results directly against an A-level offer.
In practice, equivalence tables published by UK universities give families a clearer picture than tariff points alone. The University of Surrey's entry requirements for Irish applicants set out sample grade mappings, showing how a typical pattern of Higher-level grades lines up against a standard A-level offer such as AAA or ABB. Surrey's guidance also stresses that each university sets its own conversion, so a pattern that satisfies one course's entry requirements may not satisfy another.
A few points worth keeping in mind when reading these tables:
- UCAS tariff points are a general currency, but many competitive courses also set specific subject grade requirements that tariff points alone won't satisfy.
- Universities publish their own Leaving Cert equivalence pages precisely because a blanket points comparison can mislead applicants about subject-specific demands.
- A strong spread of H2s and H3s across six subjects can match or exceed a three A-level offer once converted, depending on the course.
Why the Leaving Cert is often seen as harder, and which students each system suits
Several structural features feed the perception that the Leaving Cert is the tougher qualification. Students sit more subjects, almost everything rests on a concentrated block of written exams, and coursework plays a far smaller role than in many A-level subjects. That combination compresses two years of study into a few intense weeks each June, with far less room to recover from an off day than a system with staged assessment.
National commentary has picked up on this directly. An opinion piece in the Irish Times argues that the Leaving Cert's breadth and concentrated terminal assessment make it more demanding than A-levels, while also crediting that same breadth with producing well-rounded students. The piece reflects a wider debate in Irish education about whether a single high-stakes exam period is the fairest way to measure two years of work.
Neither system suits every learner. A student who performs consistently across varied subjects, enjoys breadth and hasn't locked in a single degree path tends to do well with the Leaving Cert. A student who knows their intended subject, performs better with staged assessment, or wants some coursework weighting to offset exam-day nerves often does better on A-levels. The honest answer depends less on which system is "harder" and more on how a specific student learns and copes with pressure.
Pro Tip: If a student struggles with exam-day nerves, ask their school whether any Leaving Cert subjects they're considering carry a project or practical component, since this spreads the stakes beyond a single sitting.
Timetable and administrative facts for 2026
Families planning around the 2026 cycle need a few fixed dates. The State Examinations 2026 notice confirms that the Leaving Certificate written exams run from 3 June to 23 June 2026, with results scheduled to issue on 21 August 2026 via the Candidate Self Service Portal (CSSP). The Department has also confirmed that assessment adjustments introduced in recent years remain in place for the 2026 cohort.
A-level exams in the UK typically run through May and June, with results released in mid-August, though exact dates vary by exam board and nation, so it's worth checking directly with the relevant regulator (such as Ofqual in England or the SQA in Scotland) for the year in question.
Key dates and notes to keep on file:
- Leaving Cert written exams: 3 June to 23 June 2026.
- Leaving Cert results release: 21 August 2026, via CSSP.
- Assessment adjustments for the 2026 cohort remain in place, per the Department's notice.
- A-level timing follows a similar May to August window, confirmed separately by each UK exam board.
Which qualification to choose for CAO or UCAS applications
The qualification a student sits often matters less than which admissions system their target university uses. Leaving Cert results feed directly into the CAO points system for Irish third-level courses, while UK universities process applications through UCAS, using tariff points and equivalence tables for non-A-level qualifications. Admissions guidance generally recommends matching the qualification to the intended destination rather than trying to game one system from the other, since a destination-led choice avoids unnecessary conversion headaches later, as UCAS's own tariff guidance notes.
That said, plenty of students use one qualification to enter the other system. A strong set of Higher-level Leaving Cert grades can satisfy many UK university offers once converted, and A-levels are accepted for CAO applications too, provided the subject requirements line up. The cleanest path is usually the one that avoids a late conversion surprise.
Before settling on a system, it helps to work through a short list of questions:
- Which country, or countries, is the student likely to apply to for university?
- Does the intended course have subject-specific requirements that only one system satisfies easily?
- Has the receiving university published an equivalence table, and does the student's likely grade pattern clear the bar?
- Would staged coursework assessment suit the student better than a single concentrated exam period?
- Is there a UCAS personal statement or CAO application the student will need support with closer to the deadline, such as the guidance in writing strong UCAS personal-statement answers?
How exchange and academic-year programmes help students test a system
Reading about both systems only goes so far. A term or year spent studying inside the other system gives a far more direct sense of whether a student thrives on breadth or depth. We can help arrange placements that let students experience this firsthand before committing.
- An Academic Year in the United Kingdom places students inside UK schools to sample A-level-style specialisation directly.
- An Academic Year in Ireland lets students experience the Leaving Cert's broader subject spread from the inside.
- Shorter summer camps in Ireland give younger students an initial taste of Irish school culture without a full-year commitment.
Each placement includes vetted host families and logistics managed comprehensively, so families can focus on what the experience reveals about their child's learning style.
Support and resources available to students within each system
Both systems offer structured support, though the shape of it differs. Leaving Cert students typically access guidance counsellors within their school, grinds (private tuition) that has become common ahead of state exams, and subject-specific grind schools during study leave. Schools also provide study skills support, particularly around managing the exam-heavy final two years.
A-level students generally have access to subject tutors within school, exam board resources published directly by bodies such as AQA, Edexcel or OCR, and, in many schools, structured coursework supervision where that applies. Pastoral support tends to be built around smaller subject classes, since fewer students study each A-level combination compared with the wider Leaving Cert cohort.
Private tutoring exists in both systems and tends to concentrate around the final exam period in each case. The practical difference is where the support is weighted: Leaving Cert support often clusters around exam technique and subject breadth management, while A-level support more often targets depth and, where relevant, coursework quality across the two-year course.
Typical student profile and suitability factors for each system
A student who thrives under the Leaving Cert typically hasn't narrowed down a single degree subject yet, performs reasonably consistently across varied subjects, and copes well with a concentrated exam period rather than staged assessment throughout the year. This profile suits a generalist who wants to keep options open for CAO courses that don't demand early specialisation.
A student who thrives under A-levels usually already has a strong idea of their intended degree subject, prefers depth over breadth, and benefits from any coursework weighting that eases pressure off a single exam sitting. This profile suits a specialist heading towards a UK university course with clear subject prerequisites, such as medicine, engineering or a single-honours humanities degree.
Students who are undecided on both subject and destination often benefit most from direct exposure to each system rather than guesswork based on reputation alone, which is where a trial term or year abroad tends to clarify the decision faster than research alone.
Cost implications of choosing either system when studying abroad
Studying under either system abroad carries direct and indirect costs worth planning for. Leaving Cert exam entry fees are set annually by the State Examinations Commission, while A-level exam board entry fees are set independently by each UK board and vary by subject and sitting. Families studying a system outside their home country also need to budget for accommodation, travel and, in some cases, private tuition to bridge any curriculum gaps.
For families considering a placement abroad to sample a system before committing long-term, programme costs vary by length and destination. A Mini Stay runs from €740 to €1,150 per person as a short introduction, while a full Academic Year in the United Kingdom costs between €8,900 and €25,900 per year and an Academic Year in Ireland costs between €13,500 and €24,800 per year, depending on the school and accommodation arrangement. These figures sit alongside, not instead of, any exam board fees the receiving school charges directly.
Weighing these costs against the value of first-hand exposure to a system often makes the decision easier than relying on reputation or hearsay alone.
Matching the qualification to the student, not the headlines
The "which is harder" debate makes for good newspaper copy, but it misses the more useful question: which system fits this particular student's learning style and university goal? Breadth versus depth, staged assessment versus a single exam window, these are personal fit questions, not rankings.
Families serve their children best by consulting official sources, such as UCAS tariff tables and university entry pages, rather than general reputation, and by considering a short exchange or preview term when the choice still feels unclear.

FAQ
What are the key differences between A-levels and GCSEs?
A-levels are a two-year qualification usually taken in three or four subjects chosen by the student, while GCSEs cover a broader range of compulsory and optional subjects completed earlier. GCSEs lay the groundwork and determine A-level subject choices, whereas A-levels feed directly into university applications.
What is the highest Leaving Cert score possible?
The highest Leaving Cert grade per subject is an H1 at Higher level, worth 36 UCAS tariff points when converted for UK applications, according to the UCAS Tariff guide. CAO points use a separate points scale that rewards a strong spread of H1s and H2s across a student's best six subjects.
What is 70% as an A-level grade?
A-level grade boundaries are set by each exam board for each subject and sitting rather than fixed at a universal percentage, so 70% doesn't map to one single grade across all subjects or years. Students should check grade boundaries published directly by their specific exam board, such as AQA or Edexcel, for the relevant subject and series.
Is maths one of the hardest A-levels?
Maths is widely regarded as one of the more demanding A-levels because of its cumulative structure, where weaker foundations in early topics make later modules harder to grasp. It remains a popular and widely taken subject, and difficulty ultimately depends on a student's grounding from GCSE maths and their comfort with abstract problem-solving.
Is the Leaving Cert harder than A-levels?
The Leaving Cert is often described as more demanding because students sit more subjects under a concentrated terminal exam structure, as argued in an Irish Times opinion piece. A-levels can feel more demanding in a different way, since they require deeper specialist knowledge in fewer subjects, so the fairer comparison depends on whether breadth or depth puts more pressure on a given student.
