English Proficiency Levels


The Common European Framework of Reference for Languages (CEFR) defines six levels of English proficiency: A1, A2, B1, B2, C1, and C2. The Life series, developed by National Geographic Learning in alignment with this framework, serves as the core material that shapes the curriculum at Lhexis.

Good to Know


Today, even in an exam taken in our native language, it’s rare to score at a C2 level. While C2 is often described as "native-like proficiency," this definition is incomplete. Reaching C2 involves not only mastering grammar but also engaging in abstract thinking, academic discussions, professional communication, and understanding cultural nuances. Therefore, it is inaccurate to assume that every American or British person speaks at a C2 level.

In fact, C1 is typically reached after receiving education at the C2 level and immersing oneself fully in the language. For most learners, B2 is a high and achievable target that can be reached with consistent and high-quality lessons.

To reach B2, students should also explore some C1 and C2 content—not necessarily to master those levels, but to reinforce their B2 foundation.
