Under an agreement between the University of Pennsylvania and the University for Foreigners in Siena, Italy, the CILS (Certificate of Italian as a Foreign Language) has been activated at the University of Pennsylvania.
The official CILS Diploma, issued by the University for Foreigners in Siena, certifies your knowledge of Italian, is valid throughout the world, and does not expire (as other certificates like TOEFL do).
