Preparing for the DELF Exam (A1–B2)

updated June 2026 reading 6 min

DELF is an official, lifelong French language diploma issued by the French Ministry of Education, covering levels A1–B2. It is recognized by universities, employers, and government agencies worldwide. The key to success is a solid vocabulary for your level and familiarity with the exam format.

What is DELF?

DELF assesses four skills: listening, reading, writing, and speaking, across levels A1, A2, B1, B2. The diploma is valid indefinitely, which is beneficial for portfolios and university applications.

Advanced levels C1 and C2 are covered by a separate diploma, DALF. For citizenship and many professional scenarios, B1 is often sufficient. For information on moving to France, see our guide on French for Emigration.

Vocabulary by Level

The required vocabulary expands with each level: B1 requires a confident grasp of everyday topics (around 2,000–2,500 words), while B2 demands more abstract vocabulary and argumentative language. Build your vocabulary by topic and reinforce it through repetition. Try this flashcard:

How to Prepare

Preparation involves two main aspects. First, raise your language proficiency to the target level: build vocabulary using spaced repetition flashcards and practice speaking aloud from the start, as the oral part cannot be learned at the last minute.

Second, familiarize yourself with the exam format: work through official practice tests, get used to the structure of the written section, and practice the oral component. For timelines on reaching a specific level, see our guide How Long Does It Take to Learn French?
