The DELF (Diploma in French Language Studies) and the DALF (Diploma in Advanced French Language Studies) are official diplomas issued by the French Ministry of Education to certify the French skills of foreign students and French people who come from a non-French-speaking country and who do not have a French public secondary or higher education diploma.

The DELF and DALF are comprised of 6 independent diplomas A1, A2, B1, B2, C1, C2. The examination is composed of four compulsory tests: oral comprehension, written comprehension, written expression, and oral expression.
