„Combined school- and work-based programmes are ones where between 25% and 90% of the learning activities take place in the work environment. Evidence from OECD countries shows that labour-market outcomes of VET graduates are stronger if their programmes include substantial work-based learning time. […] In light of the evident benefits, some countries have enacted recent policies to create more work-based learning opportunities.“
