University of Copenhagen MSc Computer Science Part-Time Guide 2026

Programme Overview and Structure

The University of Copenhagen MSc in Computer Science (Part-Time) is a research-based programme designed specifically for working professionals who want to advance their computer science expertise without leaving the workforce. Delivered by the Faculty of Science at one of Europe’s highest-ranked research universities, this 120 ECTS programme spans four years and leads to a Cand.scient. (Master of Science) in Computer Science — known in Danish as datalogi.

Unlike many part-time master’s programmes that compromise on academic depth, the Copenhagen MSc CS maintains the same rigorous, research-oriented curriculum as its full-time counterpart. The programme covers the systematic processing of information and automatic computation, training students to identify and analyse complex computational problems at a high level of abstraction, apply relevant scientific methodologies, and design correct, efficient, and useful software systems.

The curriculum was originally established in 2018 and revised in 2025, reflecting the university’s commitment to keeping pace with rapid developments in areas like artificial intelligence, machine learning, and software security. Students follow a structured four-year progression: years one and two focus on restricted elective courses that build foundational competence across core computer science areas, year three offers free electives for specialisation, and year four is dedicated entirely to the thesis.

What makes this programme unique among European part-time CS masters is the mandatory employment requirement. Students must maintain relevant professional employment of at least 25 hours per week — or run their own tech business — throughout the entire programme. This ensures that the theoretical knowledge gained in coursework is continuously applied in real-world professional settings, creating a powerful feedback loop between academic learning and practical experience. For professionals comparing part-time options across Europe, the Copenhagen programme offers a distinctive blend of academic prestige and professional integration that few institutions can match.

Curriculum Breakdown and ECTS Distribution

The 120 ECTS curriculum is divided into three main components, each serving a distinct purpose in building comprehensive computer science expertise.

The restricted elective component (60 ECTS) is structured across three lists that ensure breadth of foundational knowledge:

List 1 — Foundational Computer Science (15 ECTS): Students choose two of three courses: Advanced Programming, Advanced Algorithms and Data Structures, or Advanced Computer Systems. Each course is worth 7.5 ECTS and covers essential advanced topics that underpin all further study.

List 2 — Machine Learning and AI (7.5 ECTS): Students select at least one course from a dedicated ML/AI list, ensuring every graduate has exposure to the field’s most transformative technology area. Options include Machine Learning A and B, Deep Learning, Advanced Topics in Deep Learning, Natural Language Processing, and Online and Reinforcement Learning.

List 3 — Advanced Computer Science (37.5 ECTS): The most expansive list, offering over 30 courses spanning systems, theory, software engineering, security, HCI, graphics, and applied computing. This list provides the flexibility to build expertise in areas most relevant to each student’s career trajectory.

The Danish academic year is divided into four blocks, with part-time students typically taking one course per block (approximately 30 ECTS per year). This manageable pace allows professionals to maintain their employment while progressing steadily through the programme. Students interested in how other European universities structure flexible CS programmes can explore how leading institutions are innovating postgraduate education.

AI, Machine Learning, and Deep Learning Courses

The programme places particular emphasis on artificial intelligence and machine learning, reflecting both market demand and Copenhagen’s strength as a European AI research hub.

The University of Copenhagen has a distinguished tradition in theoretical computer science, and the programme’s curriculum reflects this strength.

Thesis Options and Research Opportunities

The thesis is the capstone of the MSc programme, and Copenhagen offers students a meaningful choice in how they approach this culminating research experience.

30 ECTS Thesis

The standard thesis option dedicates one full year (4 blocks) to an independent research project. This option provides 30 ECTS of free electives, allowing students to build a broader portfolio of coursework alongside their research. It is well-suited for students who want to explore multiple areas through electives while still producing a substantial research contribution.

45 ECTS Thesis

The extended thesis option begins in Block 3 of Year 3 and continues through all of Year 4, providing significantly more time for deeper research. This option reduces free electives to 15 ECTS but is ideal for students planning to pursue a PhD or who want to produce a research contribution with greater depth and potential for publication.

Both thesis options must fall within the academic scope of the programme and are evaluated against detailed learning objectives covering scientific research principles, problem formulation, state-of-the-art methodology, critical evaluation, experimental assessment, and comprehensive reporting (including oral presentation).

Students can also take Thesis Preparation Projects (up to 15 ECTS) to develop their research direction before committing to the full thesis, and Projects in Practice (PIP) that connect academic research with professional work contexts. These projects, combined with the mandatory employment requirement, create a natural bridge between university research and industry application.

Admission Requirements and Qualifying Degrees

The Copenhagen MSc CS (Part-Time) accepts graduates from a wide range of bachelor’s programmes, with a clear distinction between automatically qualifying degrees and those requiring individual assessment.

Automatically Qualifying Degrees

Ten Danish bachelor’s programmes provide automatic admission, including Computer Science, Computer Science and Economy, Machine Learning and Data Science, and Cognitive Data Science from the University of Copenhagen, plus CS degrees from Aalborg University, Aarhus University, University of Southern Denmark, IT University of Copenhagen, and Technical University of Denmark.

KU Computer Science graduates benefit from priority admission and guaranteed placement if they apply within 3 years of completing their bachelor’s — a significant advantage in a competitive programme.

Other Qualifying Degrees

Applicants from non-qualifying programmes must demonstrate a minimum of:

• 45 ECTS in computer science including at least 7.5 ECTS in programming (covering two substantially different paradigms), 10 ECTS in computer systems architecture, and 10 ECTS in theoretical computer science
• 7.5 ECTS in mathematics covering discrete mathematics, linear algebra, or mathematical modelling

English Language Requirements

• IELTS: minimum 6.5
• TOEFL: minimum 83
• Cambridge C1 or C2
• Or equivalent qualifications from English-speaking countries or international programmes

When the programme is oversubscribed, applicants are prioritised by total ECTS in computer science courses and grades in those courses — making a strong undergraduate CS performance the key differentiator for competitive entry.

Employment Requirement and Work-Study Balance

The mandatory employment requirement is the programme’s most distinctive structural feature. Unlike other part-time programmes where employment is optional, Copenhagen requires students to maintain relevant professional employment of at least 25 hours per week (or equivalent entrepreneurship) throughout the entire 4-year programme.

“Relevant employment” means work based on the student’s bachelor’s degree in a computing or technology-related role. Independent business owners qualify if their business is in a related field with revenue-generating activities, or if they are entrepreneurs associated with a public or private entrepreneurial environment.

Students must document their employment or entrepreneurship every semester, ensuring ongoing compliance. This requirement serves multiple purposes:

• Ensures that academic learning is continuously reinforced through professional practice
• Guarantees that graduates have 4+ years of relevant work experience alongside their MSc
• Creates natural opportunities for thesis research connected to real industry challenges
• Produces graduates who can immediately contribute at a senior level in their organisations

The Danish block system — with four teaching periods per year and students taking one course at a time — is particularly well-suited to the work-study balance. Rather than juggling multiple concurrent courses, students can focus intensively on a single subject each block while maintaining their professional responsibilities. This focused approach often leads to deeper learning and better academic outcomes than attempting to manage multiple part-time commitments simultaneously.
