Comparing the shortlist for MS Data Science in Ireland

8 of the 8 Ireland universities in our dataset run a programme matching MS Data Science. The 6 below are the highest-ranked of those.

Acceptance across this shortlist runs from 33% to 70%. That range matters more than any single number: a list of six universities with one at 33% and another at 70% is not six equivalent applications, and treating it as one is how students end up with an all-reach list and no offer.

Every university on this shortlist asks for about IELTS 6.5, so one preparation target covers the whole list.

Ranks here span 87 to 421. Rank is the weakest of the three columns for choosing a MS Data Science programme — it is dominated by research output and reputation surveys across the whole institution, neither of which tells you who teaches your modules or whether the department has industry links where you want to work. Use it to sanity-check, not to sort.

The practical sequence for Ireland: confirm the intake you are targeting (September), because entry requirements and funding both key off it; budget tuition of €20,000–30,000/yr against living costs of €10,000–12,000/yr rather than tuition alone, which is the most common underestimate; and check post-study work terms — Stamp 1G: up to 2 years — before you commit, since that is what converts the degree into the outcome most students are actually buying.

What the table above does not tell you

Four things decide a MS Data Science application in Ireland that no ranking column captures, and they are usually what separates an offer from a rejection at the same institution.

• Acceptance rate is institutional, not departmental. A university reporting 70% overall can run a MS Data Science programme far below that, because competitive departments carry the selective end of the distribution. Always look for the programme's own intake numbers; where they are not published, class size and the number of entry routes are decent proxies.
• The English score is a floor, not a target. IELTS 6.5 clears the gate; it does not compete. Where a programme is oversubscribed, admissions staff read the band breakdown, and a strong overall score hiding a weak Writing band is a common quiet rejection. Check whether the university sets per-section minimums as well as an overall figure — many do, and applicants routinely miss it.
• Funding decisions run on a different calendar to admissions. In Ireland the intakes are September, but most scholarship deadlines sit weeks to months ahead of the application deadline. Applying "on time" for admission and late for money is one of the most expensive ordinary mistakes in the process, and it is entirely avoidable.
• Post-study work rules are what you are really buying. Stamp 1G: up to 2 years The onward route matters too — PR: ~5 yrs. These terms are set by government policy rather than by the university, so they can change between the year you apply and the year you graduate. Verify them on the official immigration site at the point of applying rather than trusting any third-party summary, this page included.

If you are choosing between Ireland and somewhere else for MS Data Science, compare on total cost to a work permit rather than on tuition or rank. Tuition of €20,000–30,000/yr plus living costs of €10,000–12,000/yr over the length of the programme, set against what the post-study work window realistically lets you earn back, is the comparison that actually changes decisions — and it frequently reverses the ordering you get from ranking tables alone.
