Scholae is legally registered association. It has internal rules which must be accepted and signed by all participants. These regulations are subject to revision if need be. The regulations are governed by common sense, and sanctions are applied only if the rules are breached.
The rules inside Scholae are the same as those outside. The dress code of all persons must be neither neglected nor ostentatious. Similarly, behavior towards others and oneself must reflect the general attitude within the institution.
