Digital technology is gaining in importance - not only in life and work, but also in education and training. The availability of quality educational materials to prepare learners for work and life is a key factor to ensure an inclusive and equitable global society. A growing number of platforms with Open Educational Resources (OER) provide access to high-quality educational materials related to skills development. In times in which the development of knowledge is increasingly dynamic, openness in itself has emerged as a quality in education. In this context, it is key to realize the benefits of OER in the area of technical and vocational education and training (TVET). This brochure provides a brief overview of OER for TVET advocates practitioners and suggests to explore the world of OER and apply the concept in TVET.
