B1 is the level that separates people who studied French from people who can use it. It’s also the level where the most candidates fail, and the reason is structural rather than personal.
At A2, you describe. At B1, you have to justify. Every paper suddenly asks for a reason, an opinion, a comparison of two positions. French handles that with the subjunctive, the conditional, and a set of logical connectors that simply don’t exist lower down. If you want that argumentation work done with weekly correction, our online DELF B1 preparation course is built around producing and defending positions rather than drilling forms in isolation.
I’ve taught B1 for over 15 years, and the honest summary is this: it takes longer than students expect and rewards structure more than talent. Our guide to how the CEFR levels actually work explains why the B1 band is so much wider than the A1 or A2 bands. Below is the full syllabus, written as a checklist.
What Does the DELF B1 Syllabus Include?
DELF B1 covers roughly 40 grammar structures and 2,000 to 3,000 active words. The key additions are the subjunctive, the conditional, the plus-que-parfait, reported speech, full relative pronouns, the passive voice, and hypothesis with si. Themes become abstract: environment, media, work, society, and technology.
The Council of Europe calls B1 the threshold level, meaning you can deal with most situations while traveling, describe experiences and events, and briefly give reasons and explanations for opinions and plans.
That last clause is the whole level. “Give reasons and explanations.” Everything in the B1 grammar list exists to let you do that.
Which Grammar Structures Are Tested at DELF B1?
DELF B1 grammar covers all past tense contrasts including the plus-que-parfait, the conditionnel présent, the present subjunctive after a small set of high-frequency triggers, the four main relative pronouns, reported speech in the present, the passive voice, and si-clause hypothesis. Logical connectors carry equal weight.
B1 tenses, conditional, and subjunctive mood
- Passé composé, imparfait and plus-que-parfait used together in one narrative
- Futur simple in full productive use, carried forward from A2
- Infinitif passé: après avoir fini, après être parti
- Conditionnel présent: polite requests, wishes, advice, hypothetical results
- Conditionnel passé: introduced at B1 for regret and unrealized outcomes, consolidated at B2
- Subjonctif présent: formation of regular and common irregular verbs
- Subjunctive triggers at B1 are deliberately narrow: il faut que, il ne faut pas que, vouloir que, and a handful of frequent expressions. The wider range of concession, purpose, doubt, and emotion triggers belongs to B2
- Impératif with pronouns, affirmative and negative
- Gérondif and participe présent
The futur antérieur is not a B1 structure. It sits at B2, alongside the full subjunctive range.
B1 hypothesis and si-clause conditions
- si + présent → présent or futur (real, likely)
- si + imparfait → conditionnel présent (unreal, imagined)
- si + plus-que-parfait → conditionnel passé (regret about the past), introduced at B1 and mastered at B2
- Alternatives: à condition que, au cas où, sinon
B1 relative pronouns and reference words
- Relative pronouns: qui, que, où, dont
- Compound relatives: ce qui, ce que, ce dont
- Double pronoun order: je le lui donne
yandenin full use, including with verbs that govern à or de- Demonstrative pronouns: celui, celle, ceux, celles
B1 reported speech and passive voice
- Discours indirect in the present: il dit qu’il vient
- Reported questions and reported commands in the present
- Reported speech in the past, with the full tense shift and concordance des temps, is a B2 structure rather than a B1 one
- Passive voice: formation, agent with par, and when French prefers
oninstead - Nominalization at basic level: augmenter → l’augmentation
B1 logical connectors for argument building
- Cause: parce que, car, puisque, comme, en raison de, grâce à, à cause de
- Consequence: donc, alors, c’est pourquoi, par conséquent, si bien que
- Opposition: mais, cependant, pourtant, en revanche, par contre, alors que
- Concession: bien que, même si, malgré, quand même
- Addition: de plus, en outre, par ailleurs, également
- Sequencing an argument: d’une part, d’autre part, tout d’abord, enfin
That connector list deserves as much drilling as the subjunctive. It’s what turns a collection of correct sentences into an argument an examiner can follow.
Published material for this level varies a great deal in quality, particularly on the subjunctive. Our review of which DELF preparation books earn their place at B1 is worth buying.
Sources Behind This B1 Grammar Inventory
No official DELF grammar syllabus exists. The exam is defined by CEFR can-do descriptors rather than by a list of structures. This inventory is reconstructed from those descriptors, from the ministry grammar progression by level, and from B1 sample tasks.
B1 is where reference works diverge most, so the three items above carry an explicit qualifier. The conditionnel passé and the si + plus-que-parfait hypothesis are introduced here and consolidated at the B2 level. The subjunctive is real at B1 but narrow: high-frequency triggers only, not the full concession and emotion range.
Treating B1 as though it demands complete mastery of the subjunctive is the single most common way candidates over-prepare and still fail the productive papers.
What Vocabulary Do You Need for DELF B1?
DELF B1 expects 2,000 to 3,000 active words across roughly 15 broader themes. The shift from A2 is toward abstraction. You still need concrete daily vocabulary, but you also need language for problems, causes, consequences, opinions, and social issues.
The themes that dominate B1 papers:
- Work and careers: job hunting, workplace relations, career change, remote work
- Education and training: systems, choices, exams, lifelong learning
- Environment: pollution, recycling, climate, energy, transport choices
- Health and lifestyle: diet, exercise, stress, sleep, public health
- Media and internet: news, social media, screen time, misinformation
- Technology: devices, apps, automation, digital habits
- City life and housing: urban problems, transport, cost of living, neighborhoods
- Consumption and money: budgeting, advertising, online shopping, waste
- Travel and tourism: sustainable travel, cultural differences, experiences
- Relationships and society: family change, friendship, generations, community
- Culture and leisure: cinema, music, reading, festivals, opinions on culture
- Food and eating habits: local versus imported, food culture, changing diets
- Volunteering and civic life: associations, participation, rights, and duties
- Feelings and reasoning: conviction, doubt, concern, preference, regret
- Argument vocabulary: avantage, inconvénient, solution, conséquence, enjeu, débat
That last theme is the one self-studying candidates almost always skip, and it’s the one that decides your writing and speaking marks.
How Is the DELF B1 Exam Structured?
The B1 exam has four papers, each worth 25 marks. Listening runs about 25 minutes, with recordings mostly played twice. Reading is about 45 minutes across longer texts. Writing is 45 minutes for one text of 160 to 180 words. Speaking lasts around 15 minutes, including 10 minutes of preparation.
Paper by paper:
Listening. Radio extracts, interviews, announcements, and conversations. You have to catch not just facts but attitude, because questions ask what a speaker thinks, not only what they said.
Reading. Several longer texts, including at least one opinion piece. You identify main ideas, specific details, and the writer’s stance. Our guide to the DELF B1 reading paper covers each text type and question format.
Writing. One text of 160 to 180 words: an opinion essay, a formal letter, a blog post, or a forum reply. This is where connectors and the subjunctive earn their marks. The DELF B1 production écrite guide includes a corrected model answer against the official grid.
Speaking. Three parts: a guided interview, an interactive role-play, and a monologue where you present and defend a viewpoint on a drawn topic, with 10 minutes to prepare.
The collective written session runs for about 1 hour and 55 minutes. Scoring is unchanged: 50 out of 100 overall, and a minimum of 5 out of 25 in every paper.
Why Is B1 the Hardest Jump on the CEFR Ladder?
Because it’s the widest band. A2 to B1 asks for roughly 150 additional study hours, more than either level below it, and the skill being tested changes rather than just deepening.
Here’s what actually changes.
At A2, the examiner wants correct information. At B1, they want a position with support. A perfectly accurate answer that takes no stance scores poorly because it fails the criterion about expressing and justifying an opinion.
That catches strong grammar students the hardest. Indian learners often arrive at B1 with better verb tables than their European classmates and weaker argumentation skills, because school French rewards accuracy over opinion. The fix isn’t more grammar. It’s practicing the shape of an argument until it’s automatic: position, first reason with an example, second reason with an example, conclusion.
When I worked with a group preparing for B1 after two failed attempts elsewhere, we changed almost nothing about their grammar. We drilled that four-part shape until they could produce it on any topic in 40 seconds. All of them cleared the writing paper on the next attempt.
If B1 already feels out of reach rather than merely hard, the gap may be foundational rather than about argument. Check the A2 grammar checklist below B1 before committing to a session.
How Do You Know You’re Ready for DELF B1?
You’re ready when you can take a position on an unfamiliar topic and defend it for two minutes with two supported reasons, write 170 words with correct connectors and at least one accurate subjunctive, understand a radio interview at natural speed, and read an opinion column and state the writer’s stance.
Test it honestly. Pick a topic you’ve never prepared: remote work, plastic bans, mobile phones in schools. Give yourself ten minutes, then speak for two. Record it.
Listen for three things. Did you actually take a position, or did you list facts? Did you support each reason with a concrete example? Did you use connectors, or did every sentence start with je pense que?
Most learners need about 150 hours beyond A2 to comfortably reach B1, which is roughly four to five months at two sessions per week.
What Does a Sixteen-Week B1 Study Plan Look Like?
Give the subjunctive and connectors the most runway, build the argument shape from week one, and leave the last three weeks for full-time papers. Grammar and argumentation should run in parallel rather than in sequence.
Weeks 1 to 3. Plus-que-parfait and the three-tense narrative. Work, education, and city themes. Start the four-part argument shape immediately, in English if necessary, then in French.
Weeks 4 to 6. Conditional in all three uses. Hypothesis with si. Environment and health themes. Begin timed reading on longer texts.
Weeks 7 to 9. Present subjunctive after its high-frequency triggers, not the full B2 range. Relative pronouns including dont. Media, technology, and society themes. Start writing 170-word texts weekly.
Weeks 10 to 12. Reported speech, passive voice, double pronouns. Argument connectors drilled to automaticity. Speaking monologues on drawn topics, timed with 10 minutes of preparation.
Weeks 13 to 16. Full papers under exam conditions. One complete mock a week, with every writing task corrected and rewritten.
Professionals doing this alongside a job usually run it over five months rather than four, and most prefer live online French lessons for working professionals because an evening session survives a travel week better than a fixed classroom slot.
What Matters Most in the DELF B1 Syllabus
B1 is the widest step on the ladder, so budget four to five months rather than two. The subjunctive and the connector bank matter more than any other grammar on the list. And the skill genuinely being tested is argument, not accuracy, which means practicing positions is more valuable than another round of verb drills.
Print the checklist. Work only on what’s shaky. Then start defending opinions out loud.
