MOBUILDING has been designed to tackle one of the building sector’s key challenges: enhancing the mobility of apprentices and the quality of their learning experiences. The project proposes an integrated support system to increase the number, diversity and quality of apprenticeship mobility opportunities. It focuses on removing structural and institutional barriers, building capacity in VET providers and companies, and creating a European-wide digital platform to facilitate cooperation and coordination. By integrating innovative and sustainable practices to meet evolving industry standards, MOBUILDING boosts the transition to greener and more sustainable practices, essential for meeting EU Green Deal goals and its required new skills and training.
