Note: MSAP Ireland score and Open Learning module results are valid for two years only i.e. results from this year are valid for entry in this year and next year only.

Science Ability: You must show academic ability in relevant science subjects. For school-leavers at least a grade O2/H6 (OB1/HD3) in Leaving Certificate a Laboratory Science subject is required.

You will need an equivalent level to be able to cope with the modules in the first year of the Science degree programme. N.B. Evidence of ability must be provided.

Mathematics Ability: 

You must show academic ability in mathematics.

For school-leavers at least a grade O2/H6 (OB1/HD3) in Leaving Certificate Mathematics and a Laboratory Science subject is required.

You will need an equivalent level to be able to cope with the modules in the first year of the Science degree programme. N.B. Evidence of ability must be provided.

If you have not achieved the O2/H6 grade or an equivalent level, UCD offers Open Learning modules which will meet the requirement:

MATH00030 or MATH0040

The following modules are also accepted to meet the Maths requirement:

Please note previous ability in Maths, at min O2/H6 level is recommended to be successful on these modules

MATH00010 or

MATH10310 or


Motivation and Interest: Personal Statement should be included, explaining why you want to study Science and how the degree would contribute to your plans for your future career.

Is there an interview?

In general interviews are not held. In some cases an interview may be required to facilitate a decision on an application.

When will I know the decision on my application?

Offers for mature applicants will issue via CAO in Round A (early July) and must be accepted within a week.

Successful applicants will receive notification of an offer from CAO when the round issues.


If the decision of the Assessment Board is a Conditional Offer, UCD Admissions will contact the applicant by email, in advance of round A, to explain the conditions which must be fulfilled to receive an official CAO offer.


If places remain when Round A closes, these will be offered in the following CAO offer rounds to applicants on the waiting list*. As above, CAO will notify applicants if an offer has issued.

*Please note that the Assessment Board may have decided to offer all eligible applicants in Round A and therefore there may not be a waiting list for your chosen degree.

What is the UCD Access Route?

If you do not have the necessary background in mathematics and science, you should consider the UCD Access to Science, Engineering and Agriculture course.

This is a one year, part-time course specifically designed to prepare adults, who may not have the formal qualifications, for successful study at University.

Students who complete this programme with a GPA of 3.08 or above in the overall course assessment, and have applied via CAO, will be eligible to apply for a guaranteed minimum number of places.

If the number of eligible applicants exceeds the number of places available, applicants will be ranked based on their final GPA.

Access results from the current year are valid for entry in the current and following year only.

If you enter DN200 Science from the Access course, you may be exempted from 10 credits of your course in stage 1 (with the exception of compulsory or core modules).

You may also be interested in the QQI-FET entry pathway.
