It is important to find information on how absences should be excused (phone, e-mail, web app).
Absences due to medical reasons should be reported to the school as soon as possible (usually within two days, according to the school regulations). For any illness longer than three days, the school may require a doctor’s note in accordance with the school regulations.
The school must always be informed in advance of a planned absence.
For minor students, the absence letter must be signed by their legal guardian, i.e., usually one of their parents.
