What do A1, A2, B1, B2, C1 and C2 mean?
English proficiency levels A1–C2
Which English level do you need for a job? What skills and vocabulary are expected at each level?

There are two well-known scales for English proficiency: the European CEFR (A1–C2) and the international Beginner–Proficiency scale. We’ll look at the skills and vocabulary expected at each level on the CEFR (Common European Framework of Reference for Languages).
We’ve also built our own English vocabulary test, which can give you a rough sense of your level.
What beginners need to know and do
Beginner levels
