This simple guide explains the main types so you know what each one means.

What is CEFR?

CEFR is not one test. It is a level system used to describe how good someone's English is.

LevelWhat it means
A1 — BeginnerVery basic English. Can understand and use simple everyday phrases.
A2 — ElementaryCan understand common sentences and simple everyday conversations.
B1 — IntermediateCan handle normal daily situations, explain simple opinions and understand everyday English.
B2 — Upper-intermediateCan communicate more confidently, understand detailed texts and use English for work or study.
C1 — AdvancedStrong English for professional, academic and complex situations.
C2 — ProficientVery high level of English, close to native-level understanding and expression.

Many English tests and qualifications are linked to CEFR levels. For example, people often search for "B1 English test" because B1 is commonly required for certain UK visa, settlement or citizenship routes.

What is ESOL?

ESOL stands for English for Speakers of Other Languages. It is commonly used in the UK for people who are learning English for everyday life, work, study or integration.

  • ESOL can include reading, writing, speaking and listening.
  • It is often used by adult learners in colleges, training centres and community learning.
  • ESOL levels are often linked to CEFR levels.

What is IELTS?

IELTS stands for International English Language Testing System. It is one of the most recognised English tests in the world. IELTS is commonly used for university, work, professional registration, migration and visa-related purposes.

IELTS tests four skills:

  • Listening
  • Reading
  • Writing
  • Speaking

IELTS usually gives a band score from 0 to 9. Rough comparisons:

  • IELTS 4.0 to 5.0 may be around B1 level

The TOEFL iBT test is scored out of 120. TOEFL is mainly linked with academic English, so it is often used by students applying to universities.

  • SELT tests must usually be taken with an approved test provider.

Examples:
