CEFR levels explained
The Common European Framework of Reference for Languages (CEFR) is the international standard for describing language ability. It runs from A1 (beginner) to C2 (mastery), and it is the backbone of Guidelight’s English-level diagnostics.
What is the CEFR?
The CEFR is a framework published by the Council of Europe that describes what a language learner can do at each stage of proficiency. Instead of vague labels like “good English”, it defines concrete abilities — what a student can understand, say, read and write — across six levels: A1, A2, B1, B2, C1 and C2. Schools, exam boards and employers around the world use it as a common currency for language level.
The six levels
A1 — Beginner
Understands and uses familiar everyday expressions and very basic phrases. Can introduce themselves and answer simple questions about personal details when the other person speaks slowly and clearly.
A2 — Elementary
Understands sentences and frequently used expressions about areas of immediate relevance — family, shopping, work. Can describe aspects of their background and handle simple, routine exchanges.
B1 — Intermediate
Understands the main points of clear standard input on familiar matters. Can deal with most situations while travelling, produce simple connected text on familiar topics, and describe experiences, ambitions and plans.
B2 — Upper intermediate
Understands the main ideas of complex text on concrete and abstract topics. Interacts with a degree of fluency that makes regular conversation with native speakers possible without strain for either side.
C1 — Advanced
Understands a wide range of demanding, longer texts and recognises implicit meaning. Expresses ideas fluently and spontaneously, using language flexibly for social, academic and professional purposes.
C2 — Mastery
Understands with ease virtually everything heard or read. Summarises arguments and accounts coherently, and expresses themselves spontaneously, very fluently and precisely, even in complex situations.
How CEFR maps to IELTS bands
Teachers often need to translate CEFR levels into IELTS bands. The mapping is approximate — the exams measure different things — but this is the commonly accepted alignment:
- A1–A2 ≈ IELTS Below 4.0
- B1 ≈ IELTS 4.0 – 5.0
- B2 ≈ IELTS 5.5 – 6.5
- C1 ≈ IELTS 7.0 – 8.0
- C2 ≈ IELTS 8.5 – 9.0
How Guidelight measures English level
Guidelight includes a full CEFR diagnostic that students complete in one sitting: vocabulary, grammar, reading and listening comprehension, calibrated against the CEFR descriptor bank from A1 to C2. Results are reported as a CEFR level with an indicative IELTS band, and feed directly into task difficulty, story recommendations and exam-readiness estimates.
A built-in RSVP reading-speed test measures words-per-minute with comprehension spot-checks, so placement reflects genuine understanding rather than skimming. Together these give teachers a defensible, evidence-based placement for every student — without marking a single paper.
