If you are applying as an undergraduate for 2026 entry, apply through the CAO by 1 February 2026 at 17:00. Postgraduates should check individual programme pages now, since many use rolling admissions and close before any published deadline. International applicants need to move earlier still, because visa processing adds weeks that Irish institutions build into their own cutoffs.
TL;DR:
- Applying early for postgraduate programmes is crucial, as many use rolling admissions that close before the official deadlines, especially for competitive courses.
- International applicants should start preparing visa-related documents well in advance, as processing times can extend beyond application deadlines and require early submission.
- Students must verify specific application deadlines for their course type and applicant category, since restricted, mature, and special schemes close earlier than general late windows.
- Applying just before the deadline, even for undergraduate courses, increases the risk of missing out due to processing delays or capacity limits.
- Using services that assist with document checks and visa support can help prevent last-minute errors and improve chances of timely application completion.

Key CAO dates and what each one means for you
The CAO timetable for 2026 entry runs on three tiers, and the tier you apply in affects both the fee and how much time you have to research your options. Applications opened on 5 November 2025 at 12:00. From there, the schedule tightens.
- Early, discounted applications closed on 20 January 2026 at 17:00, with a €35 fee.
- Normal applications closed on 1 February 2026 at 17:00, with a €50 fee.
- Late applications run from 5 March to 1 May 2026, with a €65 fee, though this window excludes several applicant categories covered below.
Citizens Information's summary of CAO dates and fees confirms the same fee tiers and adds that late applications carry real restrictions rather than simply costing more.
Once you have applied, the Change of Mind facility lets you revise your course choices. A paid amendment window runs 5 February to 1 March, and a free window follows from 5 May to 1 July, giving you a second look once exam results and personal circumstances become clearer. After that, offers arrive in stages: Round A and Round Zero for certain categories, then Round 1 through Round 5 as places are confirmed and released. Each round carries its own acceptance deadline, so check the CAO timetable of events regularly rather than relying on a single date you noted months earlier.
Why postgraduate deadlines rarely work like CAO dates
Postgraduate admissions in Ireland generally use rolling admissions, reviewing applications as they arrive and closing once places fill, regardless of any stated deadline.
University of Galway's postgraduate admissions guidance advises applying months before the formal deadline, warning that programmes are often filled and closed early. TU Dublin's postgraduate guidance makes a similar point: course-level closing dates vary, and some shut once capacity is reached.
- Contact the programme's admissions office directly to confirm whether places remain open.
- Request reference letters and transcripts well ahead of any stated deadline.
- Check for staged requirements, such as a research proposal or departmental application form, that must arrive before the main closing date.
Pro Tip: Treat any postgraduate deadline as a latest possible date, not a target. Applying the week applications open gives you a real advantage over applying the week before they're meant to close.
Planning around visa processing as an international applicant
Non-EU applicants face a different clock. University of Limerick's postgraduate applying guidance sets a non-EU closing date around 1 July, well ahead of the general deadline, specifically to leave time for immigration paperwork before September registration. Institutions build this buffer in deliberately, and missing it usually makes a timely visa impossible.
- Confirm the institution's specific non-EU deadline rather than assuming it matches the general closing date.
- Gather certified transcripts, translated documents and proof of funds early, since translation alone can take weeks.
- Check your embassy's current visa processing times and add a margin for delays in peak application season.
- Accept any offer promptly, since the immigration clock only starts once you hold a confirmed place.
Who cannot use the late application window
Not every applicant has until May. Restricted courses, along with HEAR and DARE applicants and most mature applicants, must apply by the normal 1 February deadline, and the late window simply does not apply to them. A CAO press release reinforces that these categories must apply by 1 February at 17:00 to be considered at all.
- Restricted courses (including many in art, music, medicine and other selective disciplines) close to late applicants entirely.
- HEAR and DARE supporting documentation must reach the CAO by 10 March at 17:00.
- Mature applicant assessment forms are typically due by 1 March.
- Interviews, portfolios or aptitude tests for restricted courses generally take place in March and April, so preparation needs to start well before the February deadline.
If you miss one of these dates, contact the institution's admissions office directly. Some allow exceptional consideration, while others will only accept an application the following year.
How offers and Change of Mind fit together
Offers do not arrive all at once. Round A and Round Zero cover specific categories early, then Round 1 opens the main offer sequence, followed by Round 2 through Round 5 as places are reallocated.
- Check your CAO account regularly during offer season rather than waiting for an email.
- Accept an offer within its stated deadline or risk losing the place to another applicant.
- Use Change of Mind if a later round or your exam results open up a better option, remembering the paid window (5 February to 1 March) differs from the free one (5 May to 1 July).
- If you want to defer or query a place, contact the institution directly, since the CAO itself does not manage deferral decisions.
Watch the Available Places facility late in the cycle too: it lists courses still open after the main rounds close, which can matter if your plans change late.
A practical checklist before you apply
Different applicant types need different sequences, but all reward starting early.
- Undergraduates: apply through the CAO by 1 February 2026, register HEAR/DARE supporting documents by 10 March, and keep an eye on the CAO's official timetable for any updates.
- Postgraduates: contact admissions offices now, submit references and research proposals ahead of any published date, and treat rolling deadlines as a race rather than a fixed point.
- International applicants: confirm the institution's non-EU deadline, start gathering and translating documents immediately, and map out embassy processing times before committing to a start date.
Pro Tip: Build your own private deadline two to three weeks ahead of the official one for every document, reference or form. That buffer absorbs the delays that catch most applicants out.
Families planning an academic year in Ireland alongside university applications often find that booking accommodation and orientation support early, the same way you would apply for early-bird academic year placements, removes one more variable from an already tight calendar.
What I see applicants get wrong most often
The mistake I encounter most is treating every deadline as the same deadline. Students fixate on the CAO's 1 February date while a postgraduate programme they actually want has already closed, or an international applicant discovers their visa cannot be processed in time because they applied against the wrong cutoff. The single rule that solves most of this: find out your specific deadline for your specific pathway, then apply as early as you reasonably can.

Getting help when deadlines are tight
Meeting several deadlines at once, across CAO forms, programme-specific requirements and visa paperwork, is harder when you are doing it for the first time or from abroad. Go Study Ireland's University Placement service handles document checks, liaison with Irish institutions and visa support, so nothing slips because of a missed form.
This is worth considering if you are an international applicant racing a non-EU cutoff, or a first-time applicant unsure which documents each institution actually needs. Get in touch through the University Placement page to check what support fits your timeline.

FAQ
What is the deadline for university offers in 2026?
Offers are issued in rounds rather than on a single date: Round A and Round Zero come first for certain categories, followed by Round 1 through Round 5. Each round has its own acceptance deadline, so check your CAO account and the official timetable once offers begin.
Which university is still open for applications for 2026?
This depends entirely on the course and institution, since postgraduate programmes commonly use rolling admissions and close once places fill. Contact the specific programme's admissions office directly to confirm current availability rather than relying on a published date.
Is it too late to apply for 2026?
For most undergraduate courses, the CAO's late window runs from 5 March to 1 May 2026 with a €65 fee, though restricted courses, HEAR/DARE and mature applicants are excluded from this window. Postgraduate and international applicants should check their specific programme, since some close well before any general late deadline.
Is CAO open for 2026 applications?
The CAO opened applications for 2026 entry on 5 November 2025, with the normal closing date falling on 1 February 2026 at 17:00. A later, restricted window remains open into May for applicants who are not excluded from late entry.
