The reception, the concierge and/or the office of the janitors are places where the first encounter with the building takes place.
Generally, there is always a small room in the school foyer for the caretaker’s office. This location makes it easy to see and be informed about staff arriving or leaving the school, which is one of the functions of the caretakers.
As this model is repeated in all the schools, it is easy to identify the place to go to when one does not know how to find a room or person in the school.
In this sense, it should be noted that the janitors and caretakers keep the keys to access the rest of the school premises and classrooms.
