BA Hons Computer Science

Trinity College Dublin's Computer Science degree offers a rigorous and state-of-the-art education in computer science, balancing theory and practice in areas such as algorithms, artificial intelligence, and software systems. Ideal for curious problem solvers who love technology, the program trains students to develop solutions that propel industries from healthcare and finance to entertainment and security.

Curriculum Structure

• Year 1 (Junior Fresh)- Students gain a broad base from core modules like Mathematics I & II, Introduction to Programming, Digital Logic Design, Electrotechnology, Computers & Society, and a group-based Programming Project. The modules introduce the students to basic ideas of computation, logic, electronics, and group programming.
• Year 2 (Senior Fresh)- The focus continues deeper into comprehension with subjects such as Algorithms & Data Structures I & II, Systems Programming, Concurrent Systems & Operating Systems, Computer Architecture, Microprocessor Systems, and Software Engineering Project. Students learn Discrete Mathematics and Telecommunications as well, solidifying theory and systems-level hands-on practice.
• Year 3 (Junior Sophister)- This year incorporates advanced core modules—Symbolic Programming, Software Engineering, Computer Networks, Compiler Design, Information Management, Concurrent Systems, Artificial Intelligence—into optional combinations like Machine Learning or Computer Vision. Team and individual programming tasks and Trinity Electives are also completed by students to begin specialisation.
• Year 4+ (Master's Year / Capstone)- They take advanced courses such as Computer Graphics, Fuzzy Logic, Scalable Computing, or Human Factors, in the fourth (and fifth, in some instances) year, instructed by practitioner researchers. They do an individual or team capstone project—and, if taking an Master in Computer Science, do a paid industry internship with our corporate collaborators Intel, SAP, and Stripe.

Specialization areas: algorithms, systems programming, artificial intelligence and machine learning, software engineering, computer architecture, digital logic, telecommunications, data management, capstone projects

Learning outcomes: Graduates will create and implement effective algorithms, construct and manage sophisticated software systems, employ AI principles, understand computer hardware and networks, engage in team-based project work, and lead innovation in tech environments.

Professional alignment (accreditation): The BA (Mod) and Master in Computer Science integrated programmes are professionally accredited by Engineers Ireland.

Reputation (employability rankings): Trinity ranks 75th globally and 1st in Ireland in the QS World University Rankings 2025, and 139th in Times Higher Education rankings. Its School of Computer Science is highly renowned for good graduate performance and employer relations.
