Marked only by official IB examiners

The IB Language B course is designed for students who have some prior knowledge of a foreign language and are non-native speakers. Language B subjects belong to Group 2: Language Acquisition, and focus on developing comprehension and communication skills within the language. For a better understanding of the proficiency level gained from IB Language B, this post will benchmark the four most popular Language B subjects against the Common European Framework of Reference for Languages (CEFR)

 

 

IB Language B CEFR

 

 

What is the CEFR? 

 

In short, the CEFR is an international standard for measuring language proficiency. The higher the CEFR level, the more proficient someone is in that particular language. The CEFR scale is shown below.

N/A means that the CEFR level does not correspond to any IB grade for the particular subject. The "+" scores (e.g. B2+) are not official CEFR levels but are used within IB reporting to signify a proficiency that is between CEFR levels (i.e. B2+ is between B2 and C1).
