View topicsCCEA's post-16 computing provision in Northern Ireland is delivered through two distinct A-Levels rather than one. Software Systems Development is the programming-focused route, built around object-oriented development and a substantial software project. Digital Technology is broader, covering information systems, data management and the wider application of technology, and is the more common choice in NI schools.
Which one a student is taking matters more than it does elsewhere, because the two demand different things: Software Systems Development rewards genuine programming fluency and disciplined project work, while Digital Technology rewards structured written analysis of systems and data. Students applying to computer science degrees in Great Britain should be aware that admissions tutors are more familiar with the Software Systems Development route.
