DALF C1 and C2: what they involve and how to prepare

The DALF C1 and DALF C2 certify the French of a proficient user: the level that lets you study at a French university, work in French or teach the language. They are long, demanding exams in which language level is essential but not sufficient: you also need to master synthesis and argumentation with a precise method.

What level does the DALF C1 require?

According to France Éducation international, C1 certifies that you can express yourself spontaneously and fluently, without searching too much for words, and use French effectively and flexibly in your social, professional or academic life. In practice: you understand long, complex texts, you pick up on what is implied and you produce clear, well-structured texts on difficult subjects.

What does the DALF C1 exam look like?

To pass you need 50 points out of 100 and a minimum of 5 out of 25 in each paper. The three group papers add up to 4 hours: it is an endurance test, and you should train for it as such.

How to write the DALF C1 synthesis

The synthesis is the paper that surprises candidates most. Based on several documents, you have to write a new, objective text of 220 to 240 words that brings together their main ideas. The rules are strict:

• No personal opinion: the synthesis is neutral.
• No copying sentences from the documents: you have to rephrase.
• No presenting the documents one by one: you organise the ideas by theme, cross-referencing the sources.
• A clear title and plan, with an introduction, a body in two or three parts and a conclusion.
• Respect the word count: going outside the range is penalised.

The second exercise is then an argumentative text of at least 250 words on the same topic, this time giving your opinion. This is where linking words and the ability to qualify your ideas come into play.

How to prepare for the DALF C1 speaking paper

You have one hour of preparation with a file of documents, then 30 minutes in front of the examiners: a presentation in which you set out an issue and defend a position, followed by a discussion with the examiners.

1. Formulate a clear issue based on the documents (a question, not a topic).
2. Announce a plan in two or three parts and stick to it.
3. Use the documents as support, without reading or summarising them one after another.
4. Prepare your conclusion before the body: that way you never run out of an ending.
5. In the discussion, defend your position politely, even if the examiner takes the opposite view.

What is the DALF C2 like?

The DALF C2 has a different structure, with two papers marked out of 50. You pass with 50 points out of 100 and a minimum of 10 out of 50 in each paper.

Source: the official DALF C2 description. At C2 you are expected to have an almost complete command of the language, with precision, a rich vocabulary and the ability to adapt your register to any situation.

C1 or C2?

For most purposes (universities, employment, teaching), C1 is enough and is the level most often required. C2 makes sense if French is your main working tool: translation, university teaching or professional writing in French. My advice: if you have to choose, prepare thoroughly for C1 and pass with a comfortable margin.

How long does it take to prepare for the DALF?

The Alliance Française de Leeds estimates a total of 810 to 950 hours of learning for C1 and 1,060 to 1,200 for C2, counted from scratch. If you already have a solid B2, allow at least four to six months of specific preparation for C1, with regular personal work.

How much does the DALF cost?

It depends on the centre. In Madrid, for instance, the 2026 fees at the Institut français de Madrid are €244 for the DALF C1 and €256 for the DALF C2. Like the DELF, the diploma is valid for life.

If you are preparing for C1 or C2, in my DELF and DALF preparation lessons we train the synthesis, the essay and the speaking test with detailed corrections. To practise between lessons, you can also use DelfOnline, the platform I created to prepare for these exams.
