The DELF is an official, high-quality diploma, harmonised with the levels of the Common European Framework of Reference for Languages. This diploma is recognised worldwide and is valid for life. Depending on the level, the DELF can enhance a resume and make it easier to get a job in a company where the language spoken is French. The DELF B2, and increasingly the DALF C1, allow entry into French, European or Francophone universities, and into certain grandes écoles.

There are different DELF versions. Here is a quick explanation:

• DELF Tout Public: Designed for adults and general learners outside the standard school system.
• DELF Junior / Scolaire: Tailored for teenagers (ages 12–17) with content matching adolescent interests. Individual candidates may take the Junior version. Schools and class groups can register for the Scolaire version.
• DELF Prim: Built for children (ages 7–12) at the elementary school level.
