Early tracking occurs at age 11 (compared to the OECD average of 14), and differentiation of educational pathways has increased. Research shows a strong relation between tracks chosen and socio-economic background. At age 11, 13% of the student cohort, mostly from high socio-economic backgrounds, enters gymnasia. The Czech School Inspectorate and research on Roma find that Roma children participate less although they are ensured access by law, and that Czech students from disadvantaged backgrounds (low socio-economic levels and Roma students) are more likely to drop out. Eight working groups have been set up to implement various tasks. In the context of the economic crisis (2008-11), the proportion of 15-29 years-olds not in education and not employed increased to 12.7% but remained below the OECD average of 15.8% (see Figure 4).
