Which intake is right for a graduate in Computer Science applying to Ireland?
September is the right intake for a Computer Science graduate applying to Ireland, since it carries the widest range of MSc programs, such as TU Dublin's Advanced Software Development and Cybersecurity courses, while January covers only a limited selection, so verify your specific course's January availability directly.
The two intakes are not simply earlier or later versions of each other for Computer Science; September and January actually offer a different set of programs, so the choice is really about which specific MSc is on offer when.
September: The Main Intake for Computing Programs
September carries the widest range of Computer Science, Artificial Intelligence, Data Science, and Cybersecurity master's programs, along with more scholarship opportunities. TU Dublin, for example, currently lists numerous full time computing programs for September, including Advanced Software Development, Data Science, DevOps, and Cybersecurity, and Trinity College Dublin's MSc Computer Science: Intelligent Systems also runs on a September start.
January: Useful Only If Your Specific Course Actually Offers It
January is genuinely more limited for computing, and some universities that list a January start do so only for select programs rather than their full computing lineup. Do not choose January simply because it looks less competitive; confirm first that the exact MSc you want is actually offered that term.
My Advice
In my experience, students pick January by default assuming it is easier to get into, without checking that their preferred specialisation is even running that term. If you can meet the requirements in time, target September for the fuller choice of programs and scholarships, and use January only as a genuine fallback if you need the extra months for IELTS or PTE preparation, finances, or documentation, and only after confirming the specific course you want has a January start.

More expert answers
September is the safer default for almost any Computer Science applicant to Ireland, but it is worth knowing exactly why, since the gap between September and January is larger for CS than for some other subjects.
September vs January for Computer Science
| Factor | September intake | January intake |
|---|---|---|
| Programme choice | Widest selection of MSc Computer Science, AI, and Data Science programmes | A smaller set of postgraduate computing programmes, confirmed on Ireland's official course search |
| Scholarships | Most scholarship opportunities are tied to the September cycle | Limited scholarship availability |
| Best if | You can meet the earlier application deadline | You missed September and need a genuine backup rather than waiting a full year |
If You Miss September
January remains a reasonable fallback rather than a wasted year, since some Irish universities do run computing intakes then, but treat it as a backup plan and confirm your specific shortlisted programme actually offers it before you count on it. National College of Ireland and Dublin City University are among the institutions that have listed January-start MSc Computing options in recent cycles, though the exact modules on offer can shift year to year.
Deadlines and Visa Timing That Actually Decide This
- Application windows: most Irish universities open September-intake applications around October the previous year and close them between March and July, with earlier deadlines, often January or February, tied to scholarship consideration at universities like Trinity College Dublin and University College Dublin.
- Visa lead time: non-EU applicants typically need 8 to 12 weeks to process an Irish study visa once they hold an offer letter, so a September start effectively means having that offer secured by June or July.
- Shorter January runway: where a January computing intake genuinely exists, applications commonly stay open only until October or November the same year, leaving noticeably less time to arrange funding, visa paperwork, and accommodation than the September cycle gives you.

My Advice
In my experience, students assume every Irish university runs both intakes for every programme, then discover late that their specific target course is September-only. Confirm the exact intake availability on each university's own admissions page before you build your application timeline around it. If you are graduating this year and already missed September, start your January shortlist immediately rather than defaulting to waiting a full year.
