Secondary school instructional hours, which are also lower than the OECD average, are only about 5% lower for students aged 14 and are the same for students aged 15 (Figure 4.1). In addition, norms for students in Kazakhstan require two hours of individual and group counselling per week. In “tri-lingual" schools, students may study their own language of instruction (Russian, for example), Kazakh language and a foreign language (English, for example).
