B1 in one sentence
At B1 you can understand the main points of clear standard speech and writing on familiar matters, deal with most situations likely to arise while travelling, produce connected text on topics that interest you, and describe experiences, plans and opinions with reasons behind them.
The phrase that separates B1 from everything below it is "most situations likely to arise". It no longer says routine. Something has generalised: you are no longer running a script for the situations you have practised, you are running language flexible enough to be pointed at a situation you have not.
The other new clause is "with reasons". At A2 you can say what you prefer. At B1 you can say why, and defend it a little, which is where English starts being useful in a meeting rather than only in a shop.
What independence actually looks like
Each of these needs unrehearsed language under mild pressure. That combination is what B1 buys and what A2 cannot fake.
Complain about something and get it fixed
You explain what you bought, when, what went wrong and what you want done — and then handle the answer, which nobody scripted for you. Complaining is the classic B1 task because it requires narration, a request and a small amount of persistence, all in one exchange.
Sit through a work meeting in English
You follow the thread, you know what was decided, and when someone asks you directly you can answer in two or three sentences. What you cannot yet do is intervene in a fast disagreement between two other people — that is B2.
Read a news article and say what it said
Straightforward journalism on a familiar subject becomes readable at B1, including most of the sentence structures. Summarising it back is the part that certifies the level, because summary requires understanding the argument rather than the vocabulary.
Watch a series without subtitles and follow the plot
You lose jokes, wordplay and anything spoken over background noise, and you follow the story from beginning to end anyway. That specific ratio — plot intact, texture missing — is a reliable self-check for B1.
B1 is also the level most commonly written into official requirements: a great many settlement, citizenship and vocational thresholds sit here rather than higher, precisely because B1 is where a person can manage on their own.
How long B1 takes to reach
Cambridge English puts B1 at roughly 350–400 guided learning hours cumulatively, from no English at all. Subtracting the published A2 range leaves a step of somewhere around 150–220 hours — arithmetic on two published ranges rather than a figure anyone publishes directly, which is why it is given as a span.
That step is bigger than the whole of A2 before it, and this is where most learners meet the intermediate plateau. The cause is structural rather than motivational: the levels are not equal-sized. Each one covers a wider range of language than the last, so the same amount of study buys visibly less progress, and the natural conclusion — that you have stopped improving — is wrong.
B1 is also the level at which unguided exposure starts to count properly. Reading and listening for pleasure, which contributed little at A2, begins doing real work here, because there is finally enough language in place for input to be comprehensible without being simplified. The published hours do not include any of it.

The grammar that makes B1 work
B1 grammar is largely about distance — from the speaker, from the present, from certainty. Reported speech moves an utterance away from the person who said it, the passive moves the agent out of the sentence, and the conditionals move an event away from what actually happened. All three are ways of not saying things directly, which is what adult conversation mostly consists of.
The named structures above are Reported Speech and Backshift, The Passive Voice in Every Tense, The Third Conditional and Gerunds and Infinitives. In total this site publishes 18 B1 grammar lessons:
- Stative Verbs
- Past Tenses and Used To
- Perfect and Future Tenses
- Prepositions of Time and Place
- The Passive Voice in Every Tense
- Defining and Non-Defining Relative Clauses
- Reported Speech and Backshift
- Advanced Relative Clauses
- Conditionals
- Prepositions of Movement
- Linking Words
- Articles
- Pronouns and Possessives
- Modals of Ability, Permission and Advice
- Modals of Obligation
- The Third Conditional
- The Causative
- Gerunds and Infinitives
These are fewer topics than A2 carries, and each one is substantially larger. A B1 lesson is not a rule to memorise; it is a system with several branches, which is why the exercise sets matter more at this level than at any before it.

B1 vocabulary: how many words
The usual estimate for B1 is somewhere around 2,500–3,000 words. Our B1 lists carry 1,000 words across 25 topics — Opinions & Arguments, Work & Career and Problems & Solutions among them. The change from A2 is qualitative as much as numerical: these are abstract nouns and the verbs that go with them, which is what allows an opinion to be expressed rather than only a preference.

B1 against the exams
B1 is the first level all four of the major exams measure comfortably, and the point at which their scales genuinely start to discriminate between candidates.
| CEFR level | IELTS band | TOEFL iBT (1–6) | TOEFL iBT (0–120) | Cambridge exam | Cambridge Scale | Duolingo |
|---|---|---|---|---|---|---|
| A2 · Elementary | 3.0 – 4.0 | 2 – 2.5 | 24 – 43 | A2 Key | 120 – 139 | 10 – 55 |
| B1 · Intermediate | 4.0 – 5.0 | 3 – 3.5 | 44 – 71 | B1 Preliminary | 140 – 159 | 60 – 85 |
| B2 · Upper-Intermediate | 5.5 – 6.5 | 4 – 4.5 | 72 – 94 | B2 First | 160 – 179 | 90 – 115 |
These alignments are approximate, and every organisation that publishes one says so. The CEFR describes what a learner can do; an exam score summarises how one person performed on one test on one day. The two do not convert, they correspond — bands overlap at the edges, different exams disagree by half a level, and an institution’s own published requirement always outranks any comparison chart, including this one.
A B1 result is worth having if something is asking for it. If your target is a university place, note the gap between this row and the one below it — that gap is a level of language, not a matter of exam technique, and preparation courses cannot close it.
The full chart, with all six levels and the reasoning behind each column, is on the CEFR to IELTS, TOEFL and Cambridge comparison page.
Are you really at B1?
The honest test is whether you can be dropped into a conversation without preparation. Someone changes the subject to something you did not expect. Do you stay in the conversation? At B1 you do — awkwardly, with gaps, but you stay. At A2 you leave it.
The second test is what your listener does. A B1 speaker is understood by someone who is not making an effort. That is the whole content of the word "independent" in the framework, and it is a more reliable signal than any grammar checklist.
- You can explain a problem you did not rehearse, and be understood first time.
- You read straightforward journalism without a dictionary, missing some vocabulary.
- Your speech is fluent in bursts and stalls on structures rather than on words.
- You have noticed you stopped improving — the classic sign of arriving at B1, not of failing.
What comes after B1
B2 is not more B1. The work changes from acquiring structures to controlling them: choosing between two correct ways of saying something on the basis of how formal, how tentative or how emphatic you want to be. That is register, and it is what universities and employers are actually buying when they ask for B2.
The most common mistake made at this level is treating the plateau as a reason to switch to exam preparation. It is not. The way out of B1 is volume — much more input, much more writing that somebody corrects — and the exam technique is worth adding once the language is there.
