SortMySentence Educational Team August 2, 2025 10 min read

Understand the Common European Framework of Reference (CEFR) for languages. Learn what grammar, vocabulary, and sentence skills are required at each level.

What is the CEFR Framework?

The Common European Framework of Reference for Languages (CEFR) is the international benchmark for measuring language proficiency. It divides language mastery into six levels: A1 (Breakthrough), A2 (Waystage), B1 (Threshold), B2 (Vantage), C1 (Effective Operational Proficiency), and C2 (Mastery).

Understanding your target CEFR level helps you choose appropriate study materials, set realistic learning goals, and prepare effectively for standardized exams like IELTS, TOEFL, and Cambridge English.

Level A1 & A2: Basic User (Foundational Syntax)

At the A1-A2 levels, learners build core sentence patterns: basic SVO word order, present simple and past simple tenses, basic adjectives, and everyday prepositions.

Target Vocabulary: 1,000 to 2,000 words (including Oxford 3000 core words). Practice focus: Short, single-clause declarative sentences and simple daily routines.

  • A1 Focus: "I live in London. My favourite food is pizza."
  • A2 Focus: "We decided to stay home because it was raining heavily."

Level B1 & B2: Independent User (Complex Clauses & Exams)

B1-B2 represents the transition to independent communication and academic readiness. Learners master relative clauses, reported speech, passive voice, conditionality, and academic collocations.

Target Vocabulary: 3,000 to 5,000 words. B2 is the minimum level required by most international universities and corporate employers.

Level C1: Proficient User (Academic & Professional Mastery)

C1 learners communicate with nuance, precision, and stylistic flexibility. They use inverted sentence structures, dense nominalisations, formal stance markers, and advanced cohesive devices effortlessly.

Target Vocabulary: 8,000+ words. C1 corresponds to IELTS Band 7.5-8.5 or TOEFL iBT 100-115.
