What is CEFR? The language levels A1 to C2 explained

If you have been placed in an “A2 group” on a language course or seen “B2 English required” in a job ad, you have met the CEFR. This guide explains what it is, what the six levels mean and how to relate them to vocabulary study.

What is the CEFR?

The CEFR (Common European Framework of Reference for Languages) was developed by the Council of Europe and published in 2001, and later expanded with a companion volume. Its purpose is to describe language proficiency on a common scale across languages and countries.

It defines six levels:

What the levels describe

Levels are described with “can do” statements, so they define what you can do, not a list of facts you know.

• A1: You understand and use very basic everyday expressions; you can introduce yourself and ask and answer simple questions.
• A2: You handle simple, direct exchanges on familiar topics such as shopping, your surroundings and routines.
• B1: You understand the main points on familiar matters and can describe experiences, plans and opinions in simple terms.
• B2: You understand the main ideas of complex text and interact fluently and spontaneously.
• C1: You understand long, demanding texts and express yourself flexibly and in detail.
• C2: You understand virtually everything and can differentiate fine shades of meaning.

These are short summaries of the official descriptors; institutions may add their own interpretations.

CEFR and word counts: an important warning

You may see claims such as “2,500 words for B1”. The honest truth is that the CEFR does not give word counts. Such numbers are estimates by publishers, exam bodies or researchers, and they disagree with each other. So:

• Do not treat one source’s number as a hard threshold.
• Judge your level by what you can do, not by a word count.
• Plan vocabulary study by level, without obsessing over numbers.

We do not claim exact per-level word counts on this site either.

Which level should you aim for?

It depends on your goal:

• Basic everyday communication: A2-B1 is often a reasonable first target.
• Studying or working abroad: often B2 or above; check the institution’s own requirements.
• Advanced academic or professional use: C1 and above.

Check the requirement with the school, employer or exam, not with a general rule.

Why progress slows at higher levels

In general, early levels feel fast and later ones slow down. Reasons:

• Basic words are very frequent, so a small set covers a lot.
• Higher-level words are rarer, more abstract and more context-dependent.
• Each step needs more exposure and practice.

That is why patience, a small daily goal and regular review matter even more later on.

Studying vocabulary by level

Tying vocabulary to a level has two benefits:

1. The right difficulty: you do not waste time on words that are too easy or drown in ones that are too hard.
2. A clear sense of progress as you move from level to level.

To find your level, try the methods in how to find your CEFR level. For two practical level guides, see A1 vocabulary and B2 vocabulary.

How Frigya uses CEFR

Frigya groups words by A1, A2, B1, B2, C1 and C2. For each language you choose which levels to study, so you can do A1 in one language and B2 in another, and you can select several levels at once. In Discover, words you get right on the first try are marked as already known, so picking a level a bit low does not waste time. See Frigya’s levels page.

How the CEFR is structured: four kinds of language activity

The CEFR does not describe only a “general level”. It covers language use across four types of activity:

• Reception: reading and listening (understanding).
• Production: speaking and writing (expressing yourself).
• Interaction: conversation and correspondence between people.
• Mediation: passing on, summarising or explaining ideas or texts for someone else.

This means one person can be at different levels in different skills; for example B2 in reading and B1 in speaking. For vocabulary this matters: reading needs a wide passive vocabulary, while speaking needs a narrower but active one.

When does moving up a level make sense?

“Finishing” a level is not a single moment. It usually goes like this:

1. Texts at the new level are very hard.
2. Over time you need the dictionary less.
3. At some point you understand texts at that level comfortably but expressing yourself is still hard.
4. Production catches up, and the level is settled.

So rather than “I finished A2”, it is more realistic to say “I understand A2 texts comfortably and can form simple sentences”.

Common misunderstandings about the CEFR

“The CEFR is an exam.” No, it is a framework. Exams map their results to it, but it is not an exam itself.

“Every language takes the same time.” No. Closeness to your native language affects learning time. We do not promise exact durations.

“B2 means fluent.” B2 is a strong level but not flawless; gaps and mistakes remain.

“My word count decides my level.” A word count is only one indicator; what matters is what you can do with the words.

“I should leave lower levels behind.” The opposite: higher levels are not solid unless lower-level words stay strong.

Interpret levels by your own goal

Different people want the same level for different reasons:

This helps you choose a goal for your own needs instead of “reach the top level”.

How CEFR guides vocabulary study

If you know your level:

• Revisit one level below to strengthen your base.
• Progress at your current level.
• Glance at the next level now and then to see what is waiting.

If you do not know it, see how to find your CEFR level.

Summary

• The CEFR is a framework, not an exam.
• It has six levels: A1, A2, B1, B2, C1, C2.
• Word counts are not part of the CEFR; figures are estimates.
• Judge your level by what you can do, and pick vocabulary to match.
