They are typically reflected in the qualification a person holds, but there are currently no measurement instruments available at the international level to assess and compare those skills (OECD, 2010). In surveys, employers mention a combination of some social and emotional skills, job and occupation-specific skills and cognitive skills as the most important when recruiting higher education graduates (Humburg van der Velden and Verhagen, 2013). Empirical analyses based on employer surveys show that lack of social and emotional skills can create a strong barrier to employment, especially for low-skilled jobs (Heckman and Kautz, 2013). However, studying and/or having a job can help to further develop skills.
