Theoretical Physics
Theoretical physics explores the natural world at its most fundamental level, using mathematical theories guided by experimental investigation. For some it is the foundation for an academic career in mathematics or physics. For others it provides the basis for many career options in industry, medicine, law, finance and computing.

Specific Subjects or course requirements
Minimum Entry Requirements: Irish Leaving Certificate
To be considered for admission to a degree course at the University you must:
Present six subjects, three of which must be at grade 5 or above on higher Leaving Certificate papers or at least grade 5 in the University matriculation examination.
The six subjects above must include:
A pass in English.
A pass in mathematics (or foundation-level mathematics (see note 2)) and a pass in a language other than English
OR
A pass in Latin and a pass in a subject other than a language.
Special Entry Requirements
H3 In Mathematics and Physics
Leaving Certificate General Entry Requirements
To qualify for admission to an honours degree course at the University you must:
1 meet the minimum entry requirements (see above).
2 satisfy course specific requirements (where applicable), see above.
3 where there is competition for places, have good enough examination results to be included among those to whom offers are made (see the Leaving Certificate scoring system or Advanced GCE (A Level) scoring system).
Minimum Entry Requirements: Irish Leaving Certificate
To be considered for admission to a degree course at the University applicants must:
› Present six subjects, three of which must be at grade 5 or above on higher Leaving Certificate papers or at least grade 5 in the University matriculation examination.
The six subjects above must include:
› A pass in English.
› A pass in mathematics (or foundation-level mathematics (see note 2)) and a pass in a language other than English OR
› A pass in Latin and a pass in a subject other than a language.
Notes:
1 A pass means grade O6/H7 or above in the Leaving Certificate and grade 7 or above in the University matriculation examination.
2 Mathematics at foundation-level is acceptable for minimum entry requirements only, for all courses except nursing or midwifery courses. Irish at foundation-level is not acceptable for minimum entry requirements, course requirements or for scoring purposes.
3 Students may combine grades achieved in different sittings of their Leaving Certificate/Matriculation examinations for the purpose of satisfying minimum entry and/or course requirements, but not for the purposes of scoring. This is not permitted for Medicine.
4 Combinations of Leaving Certificate subjects not permitted:
› Physics/chemistry may not be presented with physics or chemistry.
› Biology and agricultural science may not be presented as two of the six subjects required for minimum entry requirements, and they may not be presented together to satisfy course specific requirements. However, both may be used for scoring purposes.
› Art and music may not be offered as two of the three higher Leaving Certificate grades for minimum entry requirements, but both may be used for scoring purposes.
Bonus Points for Higher Level Mathematics
All students presenting H6 or above in higher level mathematics will have 25 points added to their score for mathematics. The bonus points will only be relevant where mathematics is scored as one of a student’s six best subjects for points purposes.
An applicant’s six best results from one sitting of the Leaving Certificate will be counted for scoring purposes. Applicants may combine results from the Leaving Certificate and the Trinity matriculation examination of the same year for scoring purposes.
The minimum entry levels (points) for Trinity in recent years are available at: www.tcd.ie/study/apply/admission-requirements/ undergraduate
Age Requirement
Applicants seeking admission in 2025 must have a date of birth before 15 January 2009.
Garda Vetting
Students on courses with clinical or other professional placements may be required to undergo Garda vetting procedures prior to commencing placements. If, as a result of the outcome of the Garda vetting procedures, students are deemed unsuitable to attend clinical or other professional placement, they may be required to withdraw from their course. Students who have resided outside Ireland for a period of 6 months or more will be required to provide police clearance documentation from the country (including different states) or countries in which they resided.
Students who accept an offer will be informed of the procedures to be followed to complete the vetting process (as part of the student orientation information).
Fitness To Practice
Professional courses demand that certain core competencies are met by students in order to graduate and practice professionally after qualification. Trinity has special responsibility to ensure that all students admitted to all professional programmes will be eligible for registration by the relevant professional body upon graduation. It is important to us that our students are able to fulfil the rigorous demands of professional courses and are fit to practice.

Careers / Further progression
Graduate skills and career opportunities
Many of our graduates proceed to Ph.D. degrees in leading institutions throughout the world (such as Cambridge University, Harvard, and Imperial College London) in Mathematics and Experimental Physics, as well as Theoretical Physics. Alternatively, as this degree provides graduates with a strong foundation in highly complex problem-solving skills as well as logical and abstract thinking, a world of possibilities beckons. The broad scientific background and skills that the course develops are in great demand by employers in diverse areas, including actuarial science, patent law, journalism, weather forecasting, telecommunications, medical physics, information technology, scientific computing and teaching.
Further information
Mature Students
All undergraduate courses in Trinity are open to mature applicants. Mature student applicants are not required to satisfy the normal minimum entry requirements and are not required to meet competitive academic entry levels (such as Leaving Certificate points), but are considered in the first instance on the basis of how relevant their life, work and educational experiences are to the course(s) that they wish to pursue. In addition, all applicants should demonstrate an interest in and knowledge of their course choice(s).
In order to apply to Trinity as a mature applicant you must:
› be an EU applicant (see page 216 TCD Undergraduate Prospectus 2025)

What is Theoretical Physics?
Theoretical Physics explores the natural world at its most fundamental level, using mathematical theories guided by experimental investigation. For some it is the foundation for an academic career in mathematics or physics. For others it provides the basis for many career options in industry, medicine, law, finance and computing. Trinity provides a course which ranges widely across physics and mathematics. Its graduates are in demand for their technical skills and versatility.
Theoretical Physics: The course for you?
If you enjoy mathematics and seeing how physical theories can be developed to unlock the secrets of the universe on every scale, from the quark to the Big Bang, you will be stimulated by this course. If you want to keep a wide range of options open for the future, you can do this in Theoretical Physics. It consistently attracts a spirited and talented class that makes the most of the Trinity experience.
Your degree and what you’ll study
The course combines much of the Mathematics and Physics curricula, including several modules specifically designed with the Theoretical Physics programme in mind. The final year includes a Capstone project which is carried out working closely with individual faculty members to develop an original piece of research.
