In Atyrau, for example, the average class size of small-class and other schools is about the same and the average size of small-class schools (134 students) almost doubles the national average. By contrast, small-class schools in Kyzylorda only have 34 students on average, which more than halves the national average, and classes are on average four times smaller than in other schools. This suggests that Kyzylorda applies stricter criteria to classify a school as a small-class one.
