Materials that are to be used in lessons are announced to all students and parents by teachers at the beginning of the academic year. All students are responsible to bring their course metarials along with them or to keep them ready at their school cabinets. That students come to class as prepared for the lessons with all the necessary materials is of great importance both for her/him to follow the lesson and for the provision of a healthy education environment.  If the student comes to class with her/his course materials lacking, she/he should first inform the teacher about the situation. If the student repeats this way of behaviour, she/he is asked for an interview with the class teacher, the counsellor and the related assistant principal.
