Applied Computer Science - Dual Studies: List of all tuition-free study programs in Germany (2026/2027)

Dual studies in Applied Computer Science combine rigorous academic training in algorithms, data structures, software engineering, database systems, computer networks, and programming paradigms with paid practical experience in technology companies, IT departments, or software development firms — placing you inside real development environments from the very beginning of your studies and ensuring that theoretical foundations are continuously connected to the practical realities of how software is actually built, deployed, and maintained in professional settings. You'll develop technical depth across the core disciplines of computer science while simultaneously building the engineering judgment, collaborative working habits, and problem-solving instincts that come only from contributing to genuine projects under real conditions — learning to navigate codebases, work within development teams, meet delivery constraints, and make the countless small decisions that separate software that works in theory from software that performs reliably in production. Germany's exceptionally broad technology landscape — spanning automotive software, industrial automation, enterprise IT, fintech, e-commerce, and a growing startup ecosystem, alongside major international technology firms with significant German operations — creates an environment where dual computer science students gain practical experience across an unusually diverse range of application domains and company cultures, building a professional profile that reflects both technical competence and genuine industry exposure.
