Computer Science (Joint Honours)

Program Overview

What is Computer Science? Computer Science is concerned with the study of everything to do with computers and our relationship with them. Computer scientists are critical to the efficient running of modern societies, dealing with health, security, banking and finance, transportation, and now increasingly our interaction through social networks. Computing professionals deal with theoretical issues, solve complex problems, deal with matters of ethics and with society at large. Theoretical issues in computer science relate to the abstract notions of computation and information. The study of these issues leads, for example, to efficient and robust algorithms for problems in many areas. Applications of computer science range from artificial intelligence to health informatics, from smart cities to information security, and from educational and training systems to analysis of content on social network sites. How competitive: applicants from the EU apply through the CAO, and each Joint Honours pair of subjects is ranked on points. In round 1 of 2026, the pairs with Computer Science took from 542 to 601 points, depending on the other subject. On Trinity's indicative scale for the IB, 542 is about 40 points, and anything above 600 needs Higher Level Mathematics at 4 or better, which adds 25: 601 took about 43 points with it. Applicants from outside the EU apply to Trinity directly and are assessed individually.
