If you're filling in your CAO form, you've probably already heard plenty of opinions about which courses "pay well" — usually from people repeating what they heard a decade ago. Some of that advice still holds up. A lot of it doesn't.
This guide is a starting point for 2026 applicants who want to factor earnings into their decision without losing sight of what they actually want to study. We'll cover the fields that consistently perform well on salary, why points and pay don't always line up, and how to check the numbers for your own shortlist.
Why earnings matter (but aren't the whole story)
Nobody should pick a degree purely because of a number on a spreadsheet. You'll spend three or four years studying it and, with any luck, a few decades working in or around it. If you have zero interest in the subject, even a high salary won't make those years enjoyable.
That said, earnings data is genuinely useful for narrowing down a shortlist. If you're torn between two or three courses you're equally interested in, the financial side — starting salary, how quickly that grows, and how long it takes to recoup the cost of the degree — is a perfectly reasonable tiebreaker.
The fields that consistently top the salary tables
A few broad categories show up near the top of Irish graduate salary data year after year, for reasons that are fairly stable:
Medicine, dentistry and pharmacy
These courses have long training pipelines and high points requirements, but graduates move into a profession with strong demand, regulated pay scales, and clear progression. The trade-off is time — years of internship and specialist training before salaries reach their long-run levels.
Computer Science and software engineering
Ireland's position as a European base for major tech companies means demand for CS graduates has stayed strong even as the sector has gone through hiring cycles. Starting salaries are competitive and tend to rise quickly in the first few years.
Engineering disciplines
Civil, mechanical, electrical and chemical engineering graduates benefit from steady demand across construction, pharma, energy and manufacturing — sectors that are significant employers in Ireland. Engineering also tends to have relatively low CAO points compared to its salary outcomes, which can make it good value.
Business, finance and actuarial courses
Specialised business courses — particularly finance, actuarial and business analytics — can lead to strong starting salaries in banking, insurance and consulting, especially for graduates from universities with strong industry links.

High points doesn't always mean high ROI
One of the biggest misconceptions on the CAO is that points and pay move together. They don't, not reliably. CAO points reflect demand — how many people apply relative to the number of places — which is shaped by reputation, media coverage and how restricted a course is, not purely by what graduates go on to earn.
This cuts both ways. Some very high-points courses (Medicine and Law among them) have long training pipelines that delay full earnings for years. Meanwhile, some mid-points courses — certain engineering and tech-adjacent degrees, for example — can have excellent payback periods because fees are standard, demand for graduates is strong, and you're earning a full salary from day one after graduation.
If you want a concrete example of how this plays out between two popular choices, our head-to-head comparison of Computer Science vs Business walks through starting salary, 5-year salary and payback period for both.
How to use this data without ignoring your own interests
A practical approach for 2026 applicants: start with the courses you'd genuinely be happy to study for three or four years, then use salary and ROI data to order that shortlist. If two courses are roughly tied on interest, let the numbers decide. If one course you love has noticeably weaker ROI than the others, that's useful information too — not a reason to abandon it, but a reason to go in with realistic expectations about pay.
The key is comparing like with like: starting salary alone doesn't tell you much without knowing the cost of the course and how quickly that salary grows. That's what a proper ROI comparison gives you.

What are the highest-paying CAO courses in Ireland?
Medicine, dentistry, and pharmacy consistently lead on long-run earnings, with Computer Science, Engineering and certain Business/Finance courses close behind on starting salary and 5-year salary. The exact ranking shifts year to year, so it's worth checking current figures for each course rather than relying on reputation alone.
Should I pick a CAO course based on salary alone?
No — salary should be one input, not the only one. A high-paying course you hate is a poor long-term bet, because motivation affects whether you finish the degree and how far you progress in the career. The goal is to use salary data to break ties between courses you're genuinely interested in, not to override your interests entirely.
Do high-points CAO courses always pay more?
Not always. CAO points reflect demand for a course, which is influenced by reputation, course availability and how many students apply — not purely by graduate salary. Some lower-points courses have surprisingly strong ROI because of low fees, short payback periods or strong employment rates, while some high-points courses have long training pipelines that delay earnings.
How can I compare salaries across CAO courses before choosing?
The fastest way is to compare starting salary, 5-year salary and payback period side by side for each course you're considering, rather than relying on general reputation. The CollegeROI calculator does this for 70+ Irish courses so you can see the numbers for your actual shortlist before you submit your CAO form.
