This web-based compendium has been developed in the framework of the PROMOVET project. It presents a collection of IT-based and social-media based tools that can be used by VET trainers in their teaching practice. By integrating such tools in their teaching, VET trainers have the benefit of reaching out to the young people they teach, as these tools are very popular with youth; they are used in their everyday life for personal, educational, and professional purposes. This compendium can serve as an important resource for VET trainers, as it provides them with the core information needed with respect to these tools.
