Someone told you your English was 'good.' They were being polite.

The scale that actually matters

The Common European Framework of Reference for Languages — the CEFR — is the six-rung ladder that examiners, universities, immigration officers, and employers use to measure English ability. It runs from A1 (absolute beginner) to C2 (near-native mastery), and every major English exam maps onto it: Cambridge, IELTS, TOEFL iBT, Duolingo English Test.

The framework was developed by the Council of Europe and the most recent edition, the CEFR Companion Volume (2020), is the version exam boards and governments use today. When a UK visa says 'B1 in all four skills' or a German university says 'C1 required,' they mean this scale — not the level your language app awarded you last Tuesday.

This page covers all six levels in full: what each one really means in daily life, where it breaks down, what it qualifies you for, and which exam scores prove it. There is a single master table near the bottom if you want the data at a glance, and links to the deep-dive page for each level throughout.

A1 — Breakthrough: you can introduce yourself, and that's about it

A1 is the Council of Europe's 'Breakthrough' level. You understand isolated words and very short, rehearsed phrases. You can fill in a form with your name, nationality, and address. You can say 'Two coffees, please' and understand the answer if it's slow and predictable.

Where it breaks down: anything unscripted. A shop assistant who goes off-piste, a phone call with background noise, someone who doesn't slow down — all of these collapse communication immediately.

What it's enough for: not much in formal terms. A1 is a starting point, not a destination. No visa or university requires it as a minimum; it simply confirms you've begun.

Cambridge doesn't publish a standalone A1 exam on the main Cambridge English Scale (which runs 80–230 and covers A2–C2 for adults). In Nivelo's dataset of 2,493 completed English CEFR tests (recounted 26 September 2026), 8.4% of test-takers landed at A1 — the second-smallest group, which makes sense: most people who sit a level test have been studying for at least a little while.

Cambridge's guided-learning-hours guidance estimates approximately 90–100 cumulative hours from zero to A1. At 30 minutes a day that is roughly 6 months; at one hour a day, around 3 months. These are guided hours — structured study with a teacher or quality materials — not passive time with headphones in.

→ Full breakdown: A1 English level: what it actually means

• Can do: say your name, order food, read a simple sign
• Still breaks: any spontaneous exchange, phone calls, written messages beyond a few words
• Qualifies for: nothing formal — it is a foundation only

A2 — Waystage: survival English in familiar situations

A2 is the Council of Europe's 'Waystage' level. You can handle routine tasks — buying a train ticket, exchanging pleasantries with a colleague, understanding a simple text message — as long as the situation is familiar and the other person is patient.

Three concrete examples: (1) You call a hotel to confirm a booking and follow the main information, provided the receptionist speaks clearly. (2) You write a short WhatsApp to a friend explaining you'll be late. (3) You fill in an employment form and understand the basic questions.

Where it breaks down: the moment topics get abstract or the pace picks up. A joke that depends on timing or wordplay? Gone. A phone call with a bad line or a thick regional accent? You'll catch perhaps half of it and guess the rest.

What it's enough for: A2 meets the threshold for many family reunion visas and some lower-tier work visas in several countries — though requirements change, so always verify with the issuing authority. It is not enough for university study.

The Cambridge A2 Key exam (formerly KET) certifies this level. On the Cambridge English Scale (80–230), A2 maps to approximately 120–139. In Nivelo's data, 42.3% of test-takers score at A2 — by far the largest group, reflecting the huge number of learners who are past the very beginning but not yet independent.

Cambridge estimates approximately 180–200 cumulative hours from zero to A2. At 30 minutes a day: about 12–13 months. At one hour a day: about 6–7 months.

→ Full breakdown: A2 English level: what it really means

• Can do: handle routine errands, read simple messages, exchange basic information at work
• Still breaks: abstract conversations, fast speech, poor audio quality, humour
• Qualifies for: some family/work visas (verify per country); not university entry

B1 — Threshold: independent in everyday life, dependent in complex ones

B1 is the Council of Europe's 'Threshold' level — the point at which you become a genuinely independent language user in familiar, everyday contexts. You can describe experiences, give reasons, express opinions on topics you know well, and handle most travel situations without preparation.

Three concrete examples: (1) You phone a utility company, explain a billing error, and understand the solution they offer — even if you have to ask them to repeat once. (2) You write a clear, polite work email requesting information. (3) You follow a TV documentary on a topic you know, catching the main argument even when the presenter speaks at natural speed.

Where it breaks down: precision under pressure. If the topic is unfamiliar, if the speaker has a strong accent, or if you need to make a nuanced argument in a meeting, B1 is not enough. You understand the gist but miss the detail that matters.

What it's enough for: B1 is the English requirement for the UK Skilled Worker visa and for settlement (using an approved Secure English Language Test — see the visa section below), and for equivalent routes in several other countries. It is not sufficient for university-level academic study.

IELTS Academic or General Training approximately 4.0–5.0 corresponds to B1, per IELTS' published CEFR comparison. On the new TOEFL iBT 1–6 scale (introduced 21 January 2026), B1 corresponds to approximately band 3.0–3.5. The Duolingo English Test places B1 at approximately 60–95.

Cambridge's B1 Preliminary exam (formerly PET) certifies this level, sitting at approximately 140–159 on the Cambridge English Scale. Cambridge estimates approximately 350–400 cumulative hours from zero to B1. At 30 minutes a day: roughly 23–26 months. At one hour a day: around 12–13 months.

In Nivelo's data, 28.4% of test-takers score at B1, making it the second most common result after A2.

→ Full breakdown: B1 English level: what it actually means | A2 vs B1: how to tell which level you're at

• Can do: manage travel, write work emails, follow familiar topics in the media
• Still breaks: unfamiliar accents, abstract arguments, precise professional communication
• Qualifies for: many work and family visas (with an approved test); not academic study

B2 — Vantage: the real threshold for academic and professional life

B2 is the Council of Europe's 'Vantage' level, and it is arguably the most important rung on the ladder for most learners with a practical goal. At B2 you can understand the main ideas of complex text on both concrete and abstract topics, interact with a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible, and produce clear, detailed text on a wide range of subjects.

Three concrete examples: (1) You join a video call with three native-speaker colleagues and follow the discussion well enough to contribute — you miss an idiom here and there but nothing important. (2) You write a formal complaint email that is structured, persuasive, and grammatically sound. (3) You watch a podcast on an unfamiliar topic and understand enough to explain the argument to someone else.

Where it breaks down: nuance, speed, and implicit meaning. A joke that depends on a cultural reference you don't share. A seminar speaker who uses hedged academic language ('one might argue that…'). A negotiation where the other side is using deliberate ambiguity. These still trip you up.

What it's enough for: B2 is the minimum requirement for most undergraduate and many postgraduate university admissions worldwide. It is also the level at which most employers consider a candidate functionally capable in an English-speaking workplace — though C1 is increasingly expected for competitive roles.

IELTS approximately 5.5–6.5 corresponds to B2. On the new TOEFL iBT 1–6 scale, B2 is approximately 4.0–4.5. The Duolingo English Test places B2 at approximately 100–125. The Cambridge B2 First exam (formerly FCE) certifies this level at approximately 160–179 on the Cambridge English Scale.

Cambridge estimates approximately 500–600 cumulative hours from zero to B2. At 30 minutes a day: roughly 3–3.5 years from zero (or about 12–18 months if you're already at B1). At one hour a day: 18 months to 2 years from zero.

In Nivelo's data, only 13.4% of test-takers score at B2 — a significant drop from B1, which reflects how genuinely demanding the step up is.

→ Full breakdown: B2 English level: what it means | B1 vs B2: the real difference

• Can do: hold spontaneous conversations, write formal documents, follow complex media
• Still breaks: fast implicit humour, hedged academic argument, high-stakes negotiation nuance
• Qualifies for: most university admissions; functional professional English in most sectors

C1 — Effective Operational Proficiency: the level that unlocks almost everything

C1 is the Council of Europe's 'Effective Operational Proficiency' level. You can understand a wide range of demanding, longer texts, use language flexibly and effectively for social, academic, and professional purposes, and produce clear, well-structured, detailed text on complex subjects.

Three concrete examples: (1) You give a ten-minute presentation at a work conference, handle questions you didn't prepare for, and even land a joke that the room gets. (2) You read an academic journal article in your field and not only follow the argument but critique it in writing. (3) You phone a bank with a bad line, explain a complex dispute, and persuade the agent — in real time, without a script.

Where it breaks down: the outer edge of idiom and register. A C1 speaker might still pause on a densely packed piece of literary prose or misread the exact social register in a room full of native speakers with shared cultural history. It is not nothing — but it is narrow.

What it's enough for: C1 is the threshold for competitive postgraduate programmes (many require it explicitly). In practice, it is also the level most skilled-worker employers actually need, even when they write 'B2' in the job description — because B2 describes functional competence, not fluent professional communication.

IELTS approximately 7.0–8.0 corresponds to C1. On the TOEFL iBT 1–6 scale, C1 is approximately 5.0–5.5. The Duolingo English Test places C1 at approximately 130–150. The Cambridge C1 Advanced exam (formerly CAE) certifies this level at approximately 180–199 on the Cambridge English Scale.

Cambridge estimates approximately 700–800 cumulative hours from zero to C1. At 30 minutes a day from scratch: roughly 4–5 years. At one hour a day: around 2–2.5 years.

In Nivelo's data, 7.5% of test-takers score at C1 — a significant minority, and a reminder that most learners never reach this level without deliberate, sustained effort.

→ Full breakdown: C1 English level: what it means | B2 vs C1: the real difference

• Can do: lead meetings, write academic essays, handle unexpected professional conversations
• Still breaks: densely idiomatic prose, subtle register shifts in native-speaker social settings
• Qualifies for: competitive postgraduate study; most skilled professional roles in practice

C2 — Mastery: precision, not perfection

C2 is the Council of Europe's 'Mastery' level — the top of the CEFR scale. The Companion Volume (2020) is careful to note that C2 does not mean 'native speaker.' It means you can understand virtually everything you read or hear, summarise information from different spoken and written sources, reconstruct arguments, and express yourself spontaneously, very fluently, and precisely, differentiating finer shades of meaning.

Three concrete examples: (1) You interpret consecutive speech between two professionals in a meeting, catching the pragmatic meaning behind politely worded disagreement. (2) You write a magazine essay that an editor publishes with minor changes to house style, not to your grammar. (3) A joke you tell in a second-language seminar lands — timing, register, and cultural reference all intact.

Where it breaks down: very little, linguistically. The remaining gaps are cultural and experiential, not grammatical. A C2 speaker may occasionally miss a hyper-local slang term or a deeply embedded cultural reference — things a lifelong resident would catch automatically.

What it's enough for: C2 is the level required for professional translation, interpreting, and literary writing in English as a second language. It is the credential that signals to an institution that your English will not be a variable in your work.

IELTS approximately 8.5–9.0 corresponds to C2, per IELTS' published CEFR comparison. On the TOEFL iBT 1–6 scale, C2 is approximately 6.0. The Duolingo English Test places C2 at approximately 155–160 (note: Duolingo has not published independent validation studies for A1/A2 on its scale, so treat DET scores at those levels with caution). The Cambridge C2 Proficiency exam (formerly CPE) certifies this level at approximately 200–230 on the Cambridge English Scale.

Cambridge estimates approximately 1,000–1,200 cumulative hours from zero to C2. At 30 minutes a day from scratch: roughly 6–7 years. At one hour a day: 3–3.5 years.

In Nivelo's data, just 0.1% of test-takers score at C2. That is not a rounding error — it reflects how genuinely rare this level is among people who have not been formally educated in English.

→ Full breakdown: C2 English level: what it really means | C1 vs C2: what separates them

• Can do: translate, interpret, publish, present at the highest professional level
• Still breaks: hyper-local cultural references and slang — an experiential gap, not a linguistic one
• Qualifies for: professional translation, interpreting, literary writing, elite academic roles

The master table: every level, every exam, all in one place

All exam mappings below reflect the Cambridge English Scale (80–230), IELTS' own published band descriptors, the TOEFL iBT new 1–6 band scale as announced by ETS (effective 21 January 2026), and Duolingo's published score ranges. Guided hours are Cambridge's published cumulative estimates from zero.

Which English exam do you actually need for a UK visa?

This is where a lot of people get caught out, and it's worth being completely direct about it.

For UK visa purposes — Skilled Worker, Student, Family, and most other immigration routes — the Home Office only accepts Secure English Language Tests (SELTs). As of the time of writing, the approved SELTs are: IELTS for UKVI, LanguageCert International ESOL SELT, PTE Academic UKVI, Skills for English UKVI (PSI), and Trinity College London's ISE and GESE.

Standard IELTS (the version you sit at a regular test centre for university or general purposes) is NOT the same as IELTS for UKVI, even though both are produced by IDP/British Council and look almost identical. The UKVI version must be taken at an approved UKVI test centre. Cambridge English exams — A2 Key, B1 Preliminary, B2 First, C1 Advanced, C2 Proficiency — are not on the Home Office SELT list and cannot be used for UK visa applications.

The one exception: degree-level study. A UK higher education provider sponsoring you for a degree-level course is allowed to assess your English by its own method, and that assessment satisfies the Student visa's English requirement — so the standard IELTS or Cambridge result the university accepts is enough, with no separate SELT. Below degree level (foundation and pre-sessional courses, for example) the SELT rule applies. Confirm which case you are in with the university's admissions office, and check the live gov.uk list before booking anything — providers are added and removed.

In short: Cambridge exams are excellent credentials for employers, universities, and professional recognition worldwide — but they do not substitute for a SELT when the Home Office is the decision-maker.

Why do people test lower than they think they will?

This is one of the most common and most deflating experiences in language learning, and the reasons are specific — not vague things like 'everyone overestimates themselves.'

First: apps measure recognition, not production. When you tap the correct tile on Duolingo, you are matching a known answer to a visual prompt. The CEFR measures what you can do when there is no tile — when you have to produce the word, the sentence, the argument from nothing, under time pressure. Recognition and production are different cognitive skills. A learner who has spent 400 days on an app may have strong recognition at B1 and production closer to A2.

Second: level tests decay. If you took a placement test three years ago and got B1, that result describes who you were then. Language skills that aren't used regularly regress — particularly speaking and writing, which require active production. Reading tends to hold longer; spoken fluency goes first.

Third: fluency with patient friends is not the same as B2 under exam conditions. Your friends pause for you. They rephrase. They fill in your silences charitably. An examiner — or a native-speaker colleague in a fast meeting — does none of those things. The gap between 'I can talk to my English-speaking friend for hours' and 'I can participate in a professional meeting under time pressure' is usually one full CEFR level.

Fourth: self-rating on a CV is untested by definition. 'Fluent' and 'advanced' on a CV mean nothing without a credential. A C1 Advanced certificate is a signal that transfers; a self-assessment is a guess.

In Nivelo's data (2,493 completed English CEFR tests, recounted 26 September 2026), the modal score — the most common result — is A2, at 42.3% of test-takers. That is the plateau — and it is where the gap between self-image and result lives.

How long does it actually take? What 30 minutes a day really means

Cambridge's published guided-learning-hours estimates are cumulative from zero, not per level. That framing matters. Reaching B2 doesn't mean 500–600 hours of study starting from B1 — it means 500–600 hours total from when you started learning English.

Here is what that looks like at two common study intensities:

At 30 minutes of genuine study per day (not passive listening, not scrolling — actual guided work): A1 takes roughly 3–6 months. A2 takes roughly 12–13 months total. B1 takes roughly 23–26 months total. B2 takes roughly 33–40 months (nearly 3 years) total. C1 takes roughly 47–53 months (4+ years) total. C2 takes roughly 67–80 months (5.5–6.5 years) total.

At one hour per day of genuine study: A1 takes roughly 3 months. A2 takes roughly 6–7 months total. B1 takes roughly 12–13 months total. B2 takes roughly 18–24 months total. C1 takes roughly 28–33 months total. C2 takes roughly 42–50 months total.

Two important caveats. One: these are guided-learning hours with quality instruction or materials — not time spent half-listening to a podcast while cooking. Two: if you already have a foundation (say, you learned English as a child and have been dormant), the early levels can compress significantly. If you are starting from true zero, treat these estimates seriously.

What is your actual English level right now?

The levels in this guide are most useful when you know where you actually sit — not where your app told you, not where you felt comfortable last year, and not what you wrote on your CV.

Nivelo's free 5-minute CEFR test is designed to measure production, not recognition. It gives you a result on the A1–C2 scale based on how you actually use English, not which tile you can identify. It won't replace a Cambridge or IELTS exam, but it will give you an honest baseline — the kind that tells you whether you're working toward the right goal.

Once you have a real number, the individual level guides below will tell you exactly what that level unlocks and what it takes to move up.
