English Level Test: What B1, B2 and C1 Mean, and Which Exams Prove Them

The Common European Framework of Reference for Languages, the CEFR, describes six levels of language competence. B1, B2 and C1 are the three in the middle, the ones schools, universities and employers ask for most often in English: they mark the shift from getting by to working in English without too much strain. For the full CEFR framework, from A1 to C2, there is a companion Recap; this one zooms in on the three levels that have the most dedicated English certifications.

What the B1 English level means

According to the CEFR table published by Europass, at B1 a person can follow the gist of plain, everyday speech about familiar matters — work, school, leisure. You don’t need every word, just enough of the thread when the vocabulary isn’t specialised. At the same level, a person can link sentences simply enough to describe experiences, wishes and ambitions, and briefly explain a plan or a reason.

Real-world example: someone at B1 follows a conversation between colleagues about their summer holidays without trouble, but struggles once the talk drifts into a fast-paced, jargon-heavy detail from their own field.

What the B2 English level means

At B2, comprehension climbs a step: according to Europass, a person at this level follows extended speech and lectures, tracking even complex arguments as long as the topic stays reasonably familiar. On the speaking side, the same source describes interaction with native speakers as “quite possible” with a fair degree of fluency and spontaneity — a cautious phrase, not a promise of effortless conversation.

Preparing for B2 usually means tackling longer, less guided texts than at B1: a solid study method grounded in cognitive science helps absorb that jump, since the load of vocabulary and grammar grows fast between one level and the next.

What the C1 English level means

At C1, comprehension reaches extended speech even when it isn’t clearly structured and the logical links stay only implicit, says Europass. Spoken production is fluent and spontaneous, with a precise qualifier in the original wording — “without much obvious searching”, a softer claim than an absolute never searching for words. On the reading side, C1 covers long and complex texts, both factual and literary, picking up on differences in style between writers.

The Cambridge English exams

Cambridge English describes the CEFR as an international standard on a six-level scale, from A1 to C2, and builds its own exams to map onto exactly that scale: according to Cambridge English, this lets employers and schools compare a Cambridge score against other exams in their own country.

The exam names point to the level they target: B1 Preliminary, B2 First, C1 Advanced. The score is read on the Cambridge English Scale, a single scale shared across all Cambridge exams.

Exam	Cambridge English Scale score	Level certified
B1 Preliminary	140-159	B1 (120-139 counts only as A2)
B2 First	160-179	B2
B2 First	180-190 (Grade A)	C1
C1 Advanced	180-199	C1
C1 Advanced	200-210 (Grade A)	C2

An exam’s top band does not stay inside the level named in its title: it certifies the level above. A candidate who sits B2 First and scores Grade A doesn’t walk away with a reinforced B2, but with a C1.

IELTS: the band scale

IELTS measures competence on a continuous 9-band scale, a different system from the CEFR’s fixed steps. According to IELTS, the minimum threshold for C1 falls between bands 6.5 and 7: with 6.5, many candidates reach C1 while others stay just below it, a boundary the source itself calls blurred. Higher up, a score of 8.5 or above is recognised as C2, while an 8 is still described as “borderline” between the two top levels.

For this reason IELTS prefers to talk about guidance rather than fixed equivalence: a band score points toward a CEFR level, but the conversion stays an estimate rather than an exact number.

TOEFL iBT: the new scale since 2026

The TOEFL iBT is ETS’s most widely used exam for academic English. Since January 2026 it has run on a new 1-to-6 scoring scale for each of the four skills — reading, listening, speaking, writing — replacing the older, wider-ranging point scale. On this scale, according to ETS, B1 corresponds to scores of 3-3.5, B2 to 4-4.5 and C1 to 5-5.5, each skill scored separately.

Real-world example: a candidate who scores 5 in listening and 4 in writing has, for that sitting, a C1 in listening and a B2 in writing: the 6-point TOEFL iBT returns a profile by skill, not one overall level.

How to choose an English level test

Anyone who needs to prove an English level for a university place, a competitive exam or a job usually doesn’t have to pick the test from scratch: most institutions already state which certification they accept and what minimum score they ask for. Someone who still needs to find their bearings can start from what the goal actually requires: a candidate aiming at university entrance exams with an English component often needs a Cambridge B2 or an academic IELTS, while a school transfer to another European country more often calls for a certification recognised locally, with preparation time to plan around the arrival date.

The three certifications share one trait: none of them promises a level for life. Cambridge English, IELTS and TOEFL iBT capture a competence at the moment of the test, and regular practice remains the only way to keep it from fading in the years that follow.
