All members of the teaching staff have either the two German state examinations or an equivalent master's degree with teaching qualifications. Our rule is that the teacher must have at least two years of professional experience in the German school system before they can teach at our school. Corresponding qualifications expected of the teachers of the European branch.

The class teachers and classroom teachers are responsible for the everyday welfare of their students. They are usually the first point of contact for parents. They know their pupils very well, because they observe all aspects of child development at school.
