CEFR Levels Explained: A1 to C2 for English Teachers

 CEFR levels are the six-stage international scale (A1, A2, B1, B2, C1, C2) that the Council of Europe uses to describe how well a person can understand, speak, read and write a foreign language, running from beginner through to near-native mastery. For TEFL teachers, they are the shared reference point for lesson planning, coursebook levelling and learner progress tracking.

Key takeaways

• CEFR levels run A1 (beginner) to C2 (mastery), grouped into Basic, Independent and Proficient User bands.
• The framework was published by the Council of Europe and is now the global standard for describing language ability.
• Each level has specific “can-do” descriptors covering listening, reading, speaking and writing, not a single overall score.
• Coursebooks, exams and job adverts (including TEFL job listings) routinely quote CEFR levels rather than exam grades alone.
• Teachers use CEFR descriptors to set realistic lesson goals and choose classroom activities suited to each level.
• CEFR is a proficiency framework, not an exam. Exams such as IELTS or TOEFL are separately mapped onto it.

What are the CEFR levels?

The CEFR levels are six bands, A1, A2, B1, B2, C1 and C2, that describe a learner’s practical ability to use a language in real situations. If you want the wider context first, our guide to what language proficiency actually means explains how CEFR fits alongside other proficiency models such as ACTFL. They were developed by the Council of Europe to give teachers, learners and employers a common way to talk about language ability across countries and institutions. Rather than awarding a single score, each level describes what a learner can typically do when listening, reading, speaking and writing, which makes the framework far more useful in a classroom than a raw exam percentage.

The six levels sit inside three broader bands: Basic User (A1 to A2), Independent User (B1 to B2) and Proficient User (C1 to C2). Most general English coursebooks, from beginner to advanced, are built around this exact structure, and it is the framework you will see referenced constantly once you start teaching, whether you are placing a new student, choosing a coursebook, or writing a lesson plan.

What do the CEFR level descriptors actually say?

The CEFR level descriptors set out, in plain language, what a learner can do at each stage, and the table below reproduces the Council of Europe’s official global scale wording alongside the classroom implications for each level. This is the master reference most teachers keep close at hand, because it turns an abstract framework into a practical planning tool.

Why do CEFR levels matter for TEFL teachers?

CEFR levels matter because they let a teacher plan a lesson that actually matches what a class can handle, instead of guessing from age or nationality alone. A teacher who knows a group is solidly B1 can pitch grammar, vocabulary load and task difficulty correctly from the first activity, rather than discovering halfway through the lesson that the material is too easy or far too hard.

The framework also gives schools, recruiters and coursebook publishers a shared vocabulary. A job advert asking for “B2 or above” learners, a placement test that returns a CEFR score, and a coursebook labelled “Pre-Intermediate (A2 to B1)” are all speaking the same language, and understanding that language is a basic professional skill for anyone teaching English abroad or online.

How many CEFR levels are there?

There are six main CEFR levels: A1, A2, B1, B2, C1 and C2. Some institutions add a “Pre-A1” or “A0” category for absolute beginners with no prior exposure to the language, and exam boards sometimes split levels further (for example B1+ or B2 High), but the Council of Europe’s core global scale remains six levels grouped into Basic, Independent and Proficient User bands.

It helps to think of the six levels as three pairs. A1 to A2 covers survival and everyday communication. B1 to B2 covers independent, functional use of the language in work, study and travel contexts. C1 to C2 covers near-native fluency, precision and stylistic control. Most general English classes taught by newly qualified TEFL teachers sit somewhere in the A1 to B2 range.

How do CEFR levels compare to exam scores like IELTS or TOEFL?

CEFR levels and exam scores are related but not identical, because CEFR describes ability while exams like IELTS or TOEFL measure performance on a specific test on a specific day. Exam boards publish their own alignment tables mapping band scores onto CEFR levels, and these mappings are useful for admissions and visa purposes, but they are a translation layer rather than the framework itself.

For a full breakdown of how the six CEFR bands line up against IELTS, TOEFL and other major exams, see our companion guide on English proficiency levels for effective TEFL teaching, which covers exam equivalencies in detail so this article can stay focused on the framework itself.

How much classroom time does it take to move up a CEFR level?

Moving up one CEFR level typically takes noticeably longer as learners progress, because each higher level demands a wider range of language and finer control of it. Cambridge English and other providers commonly cite roughly 200 guided learning hours to move from one level to the next at lower levels, rising to 200 or more hours between the upper levels, though individual progress varies hugely with exposure, motivation and prior language-learning experience.

How should teachers use CEFR levels when planning lessons?

Teachers should use CEFR levels as a starting point for setting task difficulty, not as a rigid label to stick on a learner and forget. A practical approach is to check the “can-do” descriptor for the group’s level, choose one or two skills to target in the lesson, and pick materials and tasks pitched slightly above the learner’s comfort zone so there is genuine progress without overwhelming them.

It also pays to keep the level descriptors visible while marking work or giving feedback. If a B1 learner is expected to “describe experiences and events, dreams, hopes and ambitions”, that descriptor doubles as a checklist for what a piece of writing or a speaking task should actually demonstrate, which makes assessment far more consistent across a teaching team. For a deeper look at how different assessment types map onto these levels, our guide on types of assessment in English language teaching is a useful next read.

What is the difference between C1 and C2?

The difference between C1 and C2 is largely a matter of ease, precision and range rather than any new category of skill. A C1 learner already handles demanding texts and complex writing competently, while a C2 learner can understand virtually everything heard or read with ease, summarise information from multiple spoken and written sources into a coherent account, and express fine shades of meaning even in complicated situations.

Very few general English classes reach C2 in a standard course, since this level reflects near-native command of the language built up over years rather than a single programme of study. Most CEFR work in a typical TEFL classroom sits comfortably within the A1 to C1 range, with C2 usually associated with specialist academic or professional training rather than general adult or young learner classes.

Can a learner be at different CEFR levels for different skills?

Yes, it is common for a learner to sit at different CEFR levels across listening, reading, speaking and writing, because each skill develops at its own pace depending on exposure and practice. A learner who watches a lot of English television might have strong B2 listening comprehension while still writing at a B1 level, and a strong reader who rarely speaks might show the reverse pattern.

This is one reason experienced teachers avoid reducing a class, or an individual student, to a single letter and number. The CEFR framework was designed with separate descriptors for each skill precisely so that a profile like “B2 listening, B1 speaking” can be recorded and planned for, rather than forcing an artificial single score onto a learner whose ability genuinely varies by skill.

Do I need to know CEFR levels to get a TEFL job?

Yes, most employers and recruiters expect a working knowledge of CEFR levels, because job adverts, coursebooks and placement tests are built around them. You will not usually be tested on the framework directly, but a solid grasp of what separates an A2 group from a B1 group is treated as basic professional literacy once you are in a classroom, and it comes up constantly in lesson planning, parent or student feedback, and staff meetings.

This is exactly the kind of practical, classroom-ready knowledge that a structured TEFL course builds systematically, rather than leaving you to pick it up by trial and error in your first few months of teaching. Our full range of TEFL courses covers CEFR-based lesson planning as a core module, whichever qualification level you choose.

Getting comfortable with frameworks like CEFR is one of the reasons structured TEFL training pays off quickly once you start teaching, and it is something our own students mention often when they talk about the support they get on the course itself. As one recent five-star review put it: “Merlin, the AI chatbot was kinda cool, on the learning platform. He was genuinely useful whenever I got stuck, and some of his comments actually made me laugh out loud haha” (Ava, Trustpilot review). That kind of on-demand support makes concepts like proficiency levels far easier to apply with real classes.

What is the difference between A2 and B1?

The difference between A2 and B1 is the shift from handling short, familiar exchanges to coping independently with everyday situations that are not fully rehearsed in advance. An A2 learner manages routine tasks such as shopping or giving basic personal information, while a B1 learner can follow the main points of standard input on familiar topics, travel with reasonable independence, and produce simple connected text describing experiences, plans and opinions.

In practical classroom terms, A2 learners generally still need heavy scaffolding and simple sentence patterns, whereas B1 learners can start producing short paragraphs and holding a conversation on familiar topics without constant teacher support. This is usually the point where students begin to feel like they can “use” the language rather than just study it.

What is the difference between B2 and C1?

The difference between B2 and C1 lies mainly in fluency, spontaneity and control of complex language, rather than in the basic ability to communicate, which is already solid at B2. A B2 learner can interact with native speakers without strain and discuss familiar abstract topics competently, while a C1 learner can follow demanding, longer texts, recognise implicit meaning, and produce well-structured, detailed writing on complex subjects using a wide range of connectors and cohesive devices.

Teachers moving a group from B2 to C1 typically spend less time on new grammar and more time refining register, idiom and precision, since the main gap at this stage is nuance rather than basic accuracy.
