Indicator shows the percentage of adult EU28 employees whose studies during their highest level of education and training involved some learning in a workplace (e.g. through apprenticeships, internships, or other forms of work-based learning), as opposed to taking place only within an educational institution (e.g. school, college or university).

Promoting work-based learning (WBL) in all its forms, with special attention to apprenticeships, constitutes a key medium-term priority for VET policy in the EU. It should be acknowledged that the indicator does not measure all forms of work-based learning (e.g. simulated learning imitating a workplace as part of classroom teaching), as it focuses only on actual learning experiences in a workplace. Work-based learning is traditionally associated with VET programmes and is more prominent in jobs in the secondary sector of the economy.
