The Certificato di Conoscenza della Lingua Italiana (Certificate of Knowledge of Italian Language), or CELI, is an internationally recognized qualification of the Italian language destined for foreigners wanting to validate their relative Italian fluency, offered by the Università per Stranieri di Perugia. It is accepted as an official qualification notably by the Italian Ministry of Education and Research and the Italian Ministry of Foreign Affairs. It is one of the qualifications used by foreigners to get entrance into any Italian university or higher education institution.
The CELI qualification represents one of the most prestigious Italian Language Examinations and is often taken by applicants with immigration, work and study needs or for pure passion.
In 2014 Co.As.It. became an accredited CELI Exam Centre, authorized by the Università per Stranieri di Perugia (University for Foreigners of Perugia) to organise and administer all levels of CELI exams.
