Each volume in this series contains past tests for the CILS exams (Certificazione di Italiano come Lingua Straniera). They have been published as part of an attempt to increase public awareness of the work done by l'Università per Stranieri di Siena. The tests are a useful tool both for individual candidates and for teachers wanting to better prepare their students for the CILS exams. A CD-ROM with audio files of the 'prove di ascolto' is included in every volume.
