The DUAL.AI.TEACH project is a forward-looking Erasmus+ initiative designed to equip teachers across Europe with the skills and competencies to both teach with AI and teach about AI. It addresses the growing gap in AI literacy among educators by developing a dual-perspective approach that integrates AI into pedagogy while also fostering students’ understanding of AI as a subject. Despite the rapid emergence of AI tools like Curipod, Eduaide.AI, and MagicSchool AI, most pre-service and in-service teachers remain unprepared to use these tools meaningfully. The project responds to this by creating five transnational Teacher Academies, an interactive AI Learning Platform with 15+ training modules and 50+ AI-enhanced lesson plans, and a formal AI Teacher Certification Framework. Over 500 educators will benefit from mobility and training, while 4,000 students will participate in over 200 classroom pilots. The initiative aligns with the Digital Education Action Plan (2021–2027) and supports EU priorities around innovation, inclusion, and digital transformation. It also promotes teacher collaboration through cross-border exchanges and fosters sustainability by producing a policy guide and scaling up the AI training program post-project. Teachers, education administrators, policymakers, and tech developers will all benefit from structured resources, certified learning pathways, and a practical roadmap to implement AI in education. By ensuring the ethical, inclusive, and effective use of AI, DUAL.AI.TEACH positions teachers at the heart of the digital transition and future-proofs European education systems through certified competences, mobility, and institutional change.
