In order to benefit from the services, you need to provide a medical certificate of disability/invalidity, valid for study purposes.
If issued in Italy, it must be a certificate of invalidity with a degree of invalidity that is at least 50% or more, or a certificate of disability, in accordance with the Italian Law 104/92.
Exemptions or reduced tuition fees (read the page tuition fees) are regulated as follows:
If students have both the certificates, the certified disability comes before (Law 104/92).
If issued abroad, it must specify the type of disability and how it affects the study, and must concern a type of disability protected by the Italian law.
If the certificate is not written in Italian, a sworn translation in Italian or English is necessary.
