Gathering evidence on what works best is key to designing holistic guidance services for individuals and the labour market. Traditional learning and career pathways are being replaced by more dynamic, 'patchier' routes and shorter job tenures. Fast-changing and more complex learning and working contexts draw more attention to continuous learning and individual mobility, making lifelong guidance pivotal. It improves people's access to career information, helps them assess it, and enables them to develop diverse skills throughout their careers.
