The Diplôme d'études en langue française (English: Diploma in French Language Studies) or DELF for short, is a degree of French-language abilities for non-native speakers of French administered by France Education International (France Éducation international or FEI) for France's Ministry of Education. It is composed of four independent diplomas corresponding to the first four levels of the Common European Framework of Reference for Languages: A1, A2, B1 and B2. Above this level, the "Proficient User" divisions are certified by the DALF. The examinations are available in four varieties:"DELF Prim" which is for Primary School students (only available at pre A1 level, A1 and A2), "DELF Junior et Scolaire" which is aimed at Secondary School students, "DELF Tous Publics" which is aimed at adults and "DELF Pro" which is aimed at people who would like to work. Each variety is worth exactly the same and results in the awarding of the same diploma, but the material is varied to ensure that it is appropriate for the target cohort. DELF is not a certificate but it is a degree valid for life and do not expire.
