Entry requirements for Irish students

• UC3M says students from EU school systems who meet the university entry rules in their own country can enter without the Spanish entrance exam (PAU). For Ireland that means meeting Irish university matriculation rules. As a guide, UCD asks for six subjects, with at least H5 in two and O6/H7 in the other four, including English and Irish. UNEDasiss converts your Leaving Cert to a score out of 10. You can raise it to a maximum of 14 using your two best weighted subjects: Leaving Cert subject grades if they appear on your UNEDasiss accreditation, or UNED PCE subject tests. Confirm the details with UC3M admissions.
• This is a competitive degree. In 2026/27 the cut-off mark on the 14-point scale was 11.677. Check UC3M’s 2027/28 weighting table to see which subjects carry weight for this degree (maths and science subjects are weighted). Also check whether UNEDasiss will include your Leaving Cert subject grades before you decide to sit PCE tests.
• English: students in English-taught groups must prove B2 English during first year. UC3M accepts a high school diploma from an English-speaking education system, so the Irish Leaving Certificate should count. You can also qualify by passing 36 ECTS taught in English in first year. You do not need Spanish B2 for this English-taught degree.

How to apply

1. Check eligibilityMake sure your expected Leaving Cert results meet Irish university entry rules (as a guide: six subjects, including English and Irish, with at least two H5s). Also check UC3M’s 2027/28 weighting table for this degree.
2. Apply to UNEDasissApply for UNEDasiss accreditation (about €36) once applications open in early 2027. Ask for your admission score, and register for PCE subject tests, such as Mathematics, if your Leaving Cert grades will not count towards the extra 4 points.
3. Pre-enrol onlineApply through the Madrid public universities pre-enrolment system, where you can list up to 12 degrees in order of preference. In 2026 the main round ran from 5 to 26 June, and foreign-system documents were due by 6 July. Confirm the 2027 dates.
4. Accept, enrol and prove EnglishIf you are offered a place, enrol and pay by the date UC3M gives you. During first year, send UC3M your Leaving Certificate as proof of B2 English through its certificate form.

Costs

• UC3M is a public university, so EU students pay the same as Spanish students. In 2026/27 this degree is in UC3M’s Type 2 price band: €19.43 per credit at first enrolment, or €1,165.80 for a full 60-credit year. On top of that you pay an administrative fee, school insurance and, as a new student, a fee for opening a file. The fee can be paid in four instalments. UNEDasiss accreditation is a separate cost of about €36.
