A group of pupils or students learning according to the curriculum for a given school year.

Numerous grades are divided into sections (e.g. 6a, 6b, 6c). Combined grades can be organised in special cases, comprising pupils of different grades. If teaching in combined grades is organised at school, the head person, setting the school curriculum, adjusts the framework of the curriculum accordingly, taking into account the possibility of full implementation of the adopted curricula. This also applies to special schools – in the cases justified by a small number of pupils or by treatment conditions in hospital wards – in which it is allowed to organise education in combined grades, consisting mainly of pupils of one type of school.
