The CEFR English levels are six bands used to describe what you can do with a language: A1, A2, B1, B2, C1 and C2. A1–A2 are Basic User levels, B1–B2 are Independent User levels, and C1–C2 are Proficient User levels.
The important word is do. CEFR is not a list of grammar rules or a fixed number of words. It describes communicative ability across activities such as reading, listening, speaking, writing, interaction and mediation. You can also be stronger in one skill than another.
English levels at a glance
| CEFR level | Common label | In practical terms |
|---|---|---|
| A1 | Beginner | You can handle very basic needs and familiar phrases when communication is simple and supported. |
| A2 | Elementary | You can manage routine everyday exchanges about familiar people, places, work and needs. |
| B1 | Intermediate | You can function independently in many familiar situations and explain experiences, plans and opinions. |
| B2 | Upper-intermediate | You can interact with enough fluency and range for many social, academic and professional situations. |
| C1 | Advanced | You can use English flexibly and effectively for complex study, work and social purposes. |
| C2 | Proficient | You can understand and express very complex meaning with precision, flexibility and fine distinctions. |
These labels are useful shorthand, but the official CEFR is more detailed. It uses "can do" descriptors rather than saying that a learner at a certain level must know a particular textbook chapter.
What does A1 English mean?
At A1, English works best in highly familiar situations. You can understand and use basic expressions, introduce yourself, ask and answer simple personal questions, and communicate when the other person is willing to speak clearly and help.
In real life, that might mean checking into a hotel with simple phrases, buying something when the transaction is predictable, giving your name and address, or understanding a short sign.
A1 does not mean "knows no English." It means your independent range is still narrow. You rely heavily on familiar wording, repetition, context and cooperative conversation partners.
An A1 example
Imagine someone asks, "What do you usually do after work?"
An A1 learner might understand parts of the question and answer with a short, prepared idea such as: "I go home. I eat dinner. I watch TV."
The language is limited, but it accomplishes a real communicative task.
What does A2 English mean?
At A2, you can deal with more everyday language without needing every exchange to be rehearsed. Topics such as family, shopping, local places, routine work and personal background become manageable.
You can usually describe simple past events, immediate needs and familiar routines. Reading extends beyond isolated signs to short, straightforward texts. Listening is easier when the topic is predictable and the speech is clear.
The jump from A1 to A2 is less about suddenly using sophisticated English and more about being able to connect basic language into useful exchanges.
What does B1 English mean?
B1 is where the word independent starts to matter.
A B1 learner can understand the main points of clear language on familiar topics, deal with many situations while travelling, produce connected text about familiar subjects, and give simple reasons for opinions or plans.
You may still search for words, simplify what you want to say and miss details in fast speech. But you are no longer limited to memorized survival exchanges.
This is also why two B1 learners can feel very different. One may read confidently but hesitate in conversation; another may speak comfortably about daily life while struggling with longer written texts.
What does B2 English mean?
At B2, English becomes usable across a much wider range of situations. The CEFR describes an independent user who can understand the main ideas of complex texts, interact with a degree of fluency and spontaneity, and produce clear, detailed language on many subjects.
In practical terms, a B2 learner can often participate actively in meetings or classes, discuss advantages and disadvantages, follow much standard media, and maintain conversations beyond predictable everyday topics.
B2 is not "perfect English." Errors still happen. Unfamiliar accents, specialist vocabulary, dense academic writing and very fast overlapping speech can still be difficult.
The difference from B1 is often visible in range, flexibility and independence. At B1, you can get through many situations. At B2, you can shape the conversation more effectively instead of mainly surviving it.
B1 vs B2: what changes?
| Situation | B1 | B2 |
|---|---|---|
| Conversation | Handles familiar topics; may pause to search for language | Sustains discussion across a wider range of topics with more spontaneity |
| Opinions | Gives reasons in relatively simple language | Develops and supports arguments with more detail |
| Listening | Gets the main points of clear standard speech | Follows more complex standard speech and extended discussion |
| Reading | Understands straightforward factual texts on familiar subjects | Handles more complex articles and viewpoints |
| Writing | Produces connected text about familiar topics | Produces clear, detailed text and develops an argument |
If you are trying to decide whether you are B1 or B2, do not use one difficult word or one good conversation as the test. Look for consistent performance across tasks.
What does C1 English mean?
At C1, you can use English flexibly for demanding purposes. Long, complex texts become more accessible, implied meaning is easier to detect, and you can express ideas fluently without constantly making obvious searches for language.
For work or university, that can mean contributing to complex discussions, writing structured arguments, adapting tone to the situation and following detailed material outside your immediate comfort zone.
C1 still does not mean knowing every English word. Vocabulary is open-ended, specialist domains create new gaps for everyone, and even highly proficient users encounter unfamiliar expressions.
If vocabulary size is the part you are curious about, how many English words you know is a different question from your overall CEFR level.
What does C2 English mean?
C2 is the highest common CEFR level. It describes extremely high control: understanding virtually everything heard or read with ease, synthesizing information from different sources, and expressing fine shades of meaning precisely.
"C2" and "native speaker" are not synonyms. CEFR describes proficiency; it does not define someone's linguistic identity or require them to know every rare word. A native speaker can also have uneven skills depending on education, context and task.
That distinction matters enough that we explore it separately in whether native English speakers know C1 and C2 words.
What CEFR actually measures
The Council of Europe describes CEFR through language use, not a single score of "English knowledge." Its framework includes reception, production, interaction and mediation, across spoken, written and other modes.
That means your English is better pictured as a profile than as one perfectly even level.
You might be B2 in reading because you read English every day, B2 in listening on familiar subjects, B1 in spontaneous speaking, and B1 in formal writing.
A course or exam may summarize that profile into one overall result, but the underlying abilities can differ. This is one reason "What is my English level?" cannot always be answered accurately by a five-minute vocabulary quiz.
Does each CEFR level have a fixed vocabulary size?
No. The CEFR itself does not define A1, B1 or C1 by a required number of words.
Vocabulary knowledge is strongly related to what you can understand and express, so researchers and learning resources sometimes estimate vocabulary ranges around proficiency levels. But those estimates depend on what counts as a "word," whether the test measures recognition or recall, the learner population and the skill being predicted.
Treat word counts as one measurement, not a conversion formula.
The same applies in the other direction: knowing thousands of words does not automatically prove that you can use them quickly in conversation. Recognition and recall are different kinds of vocabulary access.
Do not convert every test score into CEFR too precisely
IELTS, Cambridge English exams, TOEFL and other assessments can report or map results in relation to CEFR, but the scales are not interchangeable rulers.
IELTS explicitly warns that its band scores do not have a one-to-one correspondence with CEFR levels. Different tests have different tasks, purposes and scoring models.
If a university, employer or immigration authority requires a particular result, use that institution's current accepted test and score requirement. Do not rely on an unofficial conversion chart.
How can you find your English level?
Start by deciding what you need the level for.
If you need an official result for admission, employment or immigration, use an accepted standardized assessment. If you only want to guide your learning, a diagnostic assessment can be useful, but look beyond one overall label.
A better self-check asks what you can consistently do:
- Can you follow a normal conversation without asking for frequent repetition?
- Can you explain an opinion and support it when the topic changes?
- Can you read an article for meaning without translating sentence by sentence?
- Can you write a clear message, explanation or argument for the situation?
- Can you understand English outside the topics you know best?
Then compare those abilities with CEFR "can do" descriptors. Test several skills rather than treating vocabulary, grammar or reading as a complete proxy.
If your main question is specifically vocabulary breadth, a vocabulary-size estimate can answer that narrower question without pretending to measure your entire CEFR profile.
What level counts as fluent English?
There is no official CEFR level called simply fluent.
People often use "fluent" to mean that speech flows comfortably, but fluency is only one part of proficiency. A B1 learner can speak fluently about a familiar hobby while lacking the range needed for B2 overall. A C1 learner can pause or make mistakes and still clearly meet advanced descriptors.
For a fuller distinction, see what it means to be fluent in English.
If you need a practical milestone, ask what English must let you do. "I want to handle client meetings" is more useful than "I want to be fluent." The task tells you which skills and level of control matter.
How long does it take to move from one level to another?
There is no universal calendar conversion. Starting level, previous language-learning experience, intensity, quality of practice, exposure and the distance between your strongest and weakest skills all matter.
Guided-learning-hour estimates can be useful for planning, but they are not promises. If this is your main question, our guide to how long it takes to learn English explains the estimates and why calendar time varies so much.
The practical lesson is to track changes in tasks: a conversation you can now sustain, audio you can now follow, or writing you can now produce without heavy support.
Your English level is a map, not a verdict
A1 through C2 gives you a common language for describing ability. Use it to locate the next useful challenge, not to compress everything you know into one letter and number.
If you are A2 in speaking and B1 in reading, that is useful information. If your job requires B2 interaction, you now know where practice should go. If a vocabulary test gives you a large word estimate but spontaneous speech still feels difficult, train retrieval and speaking rather than chasing a bigger number.
The best level is the one that helps you make the next learning decision.
