CEFR levels explained: A1 to C2

A0, B2, C1 — these letters appear everywhere in language learning but are rarely explained clearly. Here's what each CEFR level means in practice, and how to know which one you're at.

AI-generated illustration

CEFR stands for Common European Framework of Reference for Languages. It's the international standard for measuring language proficiency — the same scale universities, employers, and visa offices use when they ask for your English level.

There are six levels: A1, A2, B1, B2, C1, and C2. (Some systems add A0 for true beginners with no prior knowledge.) Each level describes what you can do in the language, not what you've studied or how long you've practised.

The six CEFR levels

Guided learning hours to reach each level
  1. A1, Beginner: 90–100 guided hours
  2. A2, Elementary: 180–200 guided hours
  3. B1, Intermediate: 350–400 guided hours
  4. B2, Upper-Intermediate: 500–600 guided hours
  5. C1, Advanced: 700–800 guided hours
  6. C2, Proficient: 1,000+ guided hours

A1 — Beginner

You can understand and use very familiar phrases. You can introduce yourself, ask and answer simple questions about personal information, and interact in a basic way. Reading is limited to individual words and short sentences. Most IELTS band scores of 1–2 fall here.

A2 — Elementary

You can communicate in simple, routine tasks. You can describe your background, immediate environment, and things you need. Reading comprehension extends to short texts on familiar topics. Most everyday survival English is A2. Equivalent to roughly IELTS band 3.

B1 — Intermediate

B1 is the threshold for functional independence in English. You can handle most travel situations, express opinions on familiar topics, and follow the main points of clear speech on familiar subjects. Written production is simple but connected. IELTS band 4 maps roughly here. Most English learners reach B1 and plateau — see what B1 means and how to push past it.

B2 — Upper-Intermediate

B2 is where English stops being an obstacle. You can follow complex arguments, write detailed texts on various subjects, and interact with native speakers without strain. This is the minimum level most international employers and universities require. IELTS band 5.5–6.5 typically reflects B2.

C1 — Advanced

At C1, you can express ideas fluently and spontaneously without obvious searching for words. You can use language flexibly and effectively for social, academic, and professional purposes. Academic writing is sophisticated. IELTS band 7–8 corresponds to C1.

C2 — Proficient

C2 represents near-native proficiency. You can understand virtually everything heard or read, express yourself spontaneously with very high precision, and handle complex academic or professional language. IELTS band 9 is the C2 equivalent. Very few non-native speakers reach C2.

Which level do I need?

The answer depends on your goal:

  • Travel and basic daily life: A2–B1
  • Working in an international company: B2 minimum
  • University in an English-speaking country: B2–C1 (usually IELTS 6.0–7.0)
  • Academic research or senior professional roles: C1
  • Immigration to English-speaking countries: B1–B2 for most citizenship tests

How to know what level you're at

Self-assessment is notoriously inaccurate — most learners underestimate their reading and overestimate their speaking. The most reliable approach is a placement test that evaluates all eight skills against CEFR descriptors. Carna AI Tutor, in early access, is being built to place you across all eight scored skills and map you to a CEFR band.

The level is a starting point, not a verdict. Knowing where you are makes it possible to set a realistic target and measure the distance between the two.
