§1. The diocesan bishop has the right to watch over and visit the Catholic schools in his territory, even those which members of religious institutes have founded or direct. He also issues prescripts which pertain to the general regulation of Catholic schools; these prescripts are valid also for schools which these religious direct, without prejudice, however, to their autonomy regarding the internal direction of their schools.
§2. Directors of Catholic schools are to take care under the watchfulness of the local ordinary that the instruction which is given in them is at least as academically distinguished as that in the other schools of the area.
