Why does EVA have 2 head teachers?

On EVA, professors are more like a guide than a leader. They really have a lot of work to do, so they share it. As usual, administration (absences, apologies, disciplinary sanctions, etc.) are dealt with head teachers, but head teachers are also often involved in organizing cross-cutting activities that combine multi-subject knowledge and design an annual study program. They can also be consulted on the content of teaching. Students with school-related problems turn to the head teachers. They are better to be found - even if one of them is missing.
