A lack of general skills, in particular literacy and numeracy, can be an issue for employability in the longer term as it makes it more difficult to retrain to adapt to changing labour market needs. Delaying the tracking of students would contribute to tackle this lack of general skills. Tracking into general, vocational secondary and vocational training schools (the latter giving the most emphasis to practical skills and regrouping a quarter of students, Figure 12) currently takes place at age 14, as against 15-16 in most OECD countries.
