What is IB Language B?

IB Language B is a two-year IB Diploma Programme course, designed to develop your reading, writing, listening and speaking skills in a language you already have some experience with.

How does IB Language B fit in the IB Diploma Programme?

The IB Diploma Programme, designed for students aged 16-19, asks you to take six subjects: three at SL and three at HL. You’ll also need to complete the IB Core, which consists of the Theory of Knowledge (ToK), Extended Essay (EE) and Creativity, Activity, Service (CAS).

IB Language B is part of Subject Group 2: Language Acquisition in the IB curriculum.

Language B vs Language ab initio vs Language A — which is right for you?

With several different IB language options, it’s easy to get confused. Here are the key features to note:

Language B is for students who want to develop their knowledge and skills in a target language they’re already fairly familiar with. It is available at both SL and HL.

Language ab initio (which means language ‘from the beginning’) is for students with very little to no prior experience of the target language. It is only available at SL.

Language A consists of both a literature course (opens in a new tab) and a language and literature course (opens in a new tab). The literature course introduces you to the analysis of a wide range of literary texts. The language and literature course combines close analysis of written, spoken and literary texts. These courses are better suited to native or near-native speakers, and both are available at both SL and HL.

What languages can you take for IB Language B?

IB Language B has a wide range of available languages. Here are some of the most common options:

Most schools have a smaller subset to choose from, so talk to your language teacher to check what’s available at your school.

How is IB Language B assessed?

The table below includes an overview of each of the three compulsory components:

What's the difference between IB Language B SL and HL?

The content and assessment structures are the same for SL and HL, but there are some key differences:

SL requires around 150 teaching hours. For the individual oral internal assessment, the stimulus you’ll be given is a visual image that is clearly relevant to one or more of the course themes.

HL requires around 240 teaching hours. For the individual oral assessment, the stimulus you’ll be given is an excerpt from one of the two literary works you’ve studied.

Ultimately, HL has more depth and breadth than SL; it includes two literary works (which are not included in SL) and requires a higher level of competency.

How hard is IB Language B?

Though it’s generally not listed among the hardest IB subjects, IB Language B can be tricky for some students. You’ll need to develop skills in reading, writing, listening and speaking, and many students find the oral assessment nervewracking.

HL is more challenging than SL, but whether you’ll find the course hard depends on your current skill level. The fact that you’re not starting your chosen language from scratch definitely helps.

Here are just some of the pathways IB Language B can open up for you:

Is IB Language B right for you?

If you have prior experience of a language, want to develop your skills and are interested in studying or working abroad, IB Language B is well worth considering.

If you have no prior experience in your target language, go for Language ab initio (opens in a new tab) instead.

If you’re a native or near-native speaker, Language A is the best option.
