The new IB Language B assessment structure, published for first assessment in 2029, retains the familiar three-part model: Paper 1 writing is worth 25%, Paper 2 listening and reading is worth 50%, and the internally assessed individual oral is worth 25%. Standard Level and Higher Level have the same component weightings, but HL requires more complex language and uses a literary extract in the oral.
This means the new course does not introduce a radically different set of examinations. Instead, it confirms the existing balance between productive, receptive and interactive communication while clarifying what students must do in each component. Students taking examinations before 2029 remain under the current course, first assessed in 2020, although its overall assessment structure is substantially the same.
IB Language B assessment at a glance
The official IB Language B subject brief for first assessment 2029 gives the following structure for both SL and HL:
| Assessment component | What students do | Weighting |
|---|---|---|
| Paper 1: productive skills | Complete one writing task chosen from three options, using an appropriate text type | 25% |
| Paper 2: listening | Answer comprehension questions on three audio passages | 25% |
| Paper 2: reading | Answer comprehension questions on three written texts | 25% |
| Individual oral assessment | Give a presentation, discuss the stimulus with the teacher and participate in a wider thematic conversation | 25% |
External examinations therefore account for 75% of the final subject result. The individual oral is the remaining 25% and is an internal assessment, meaning it is conducted and initially assessed at school under IB procedures.
Although the outline is identical at both levels, the demands are not. HL students are expected to communicate with greater range, complexity and nuance, and they must study two literary works originally written in the target language.
Paper 1: productive skills
Paper 1 is the writing examination. Students choose one task from three and respond using an appropriate text type from the options provided with the task.
The required length is:
- SL: 250-400 words
- HL: 450-600 words
The three tasks allow for different purposes, audiences and contexts. A task might ask a student to inform a school community, reflect on an experience, persuade local residents or evaluate a social development. The appropriate response could take the form of an article, blog entry, speech, report, letter or another text type listed in the examination instructions.
What Paper 1 actually tests
Paper 1 is not simply a grammar test. It examines whether students can use the target language to communicate a relevant message in a form suited to the situation.
A strong response normally demonstrates:
- accurate and varied vocabulary and grammar
- clear development and organization of ideas
- consistent awareness of audience, context and purpose
- an appropriate level of formality
- recognizable conventions of the selected text type
- direct engagement with every part of the task
For example, a formal proposal to a school principal should not sound like a private diary entry. Even accurate language may communicate ineffectively if the register, opening, organization and conclusion do not suit the intended reader.
Before writing, identify four elements: task, audience, purpose and text type. Then select the format that allows you to fulfil the purpose most naturally. The RevisionDojo guide to the Language B paper format provides a useful overview for practising this decision under timed conditions.
Paper 2: receptive skills
Paper 2 accounts for 50% of the final grade, making receptive skills collectively the largest part of the assessment. It contains separate listening and reading sections, each worth 25%.
| Paper 2 section | Material | Weighting |
|---|---|---|
| Listening comprehension | Three audio passages | 25% |
| Reading comprehension | Three written texts | 25% |
The passages are connected to the five prescribed themes, but students are not being tested on memorized facts about particular topics. They are being assessed on their ability to understand meaning in the target language.
Listening comprehension
The listening section tests understanding of spoken language across different situations and text forms. Questions may require students to identify the main idea, retrieve a precise detail, recognize a speaker's attitude or connect information presented at different points in a passage.
Effective preparation should include more than passively playing audio. Before listening, predict likely vocabulary from the context and preview the questions where the examination format permits it. During the passage, listen for changes of speaker, contrast words, examples, opinions, numbers and cause-and-effect relationships.
If one phrase is unclear, do not mentally replay it while the recording continues. Rejoin the passage immediately, because later information may clarify the missed point.
Reading comprehension
The reading section contains three written texts and associated comprehension exercises. Students may need to identify explicit information, interpret references, distinguish fact from opinion, infer meaning from context or recognize how a text is organized.
When reading, locate evidence rather than relying on what seems generally plausible. Pronouns, connecting expressions, changes in tense and qualifying words such as “sometimes” or “primarily” often determine whether an answer is correct. RevisionDojo's IB Language B exam strategy guide explains how to turn these habits into a repeatable Paper 2 routine.
The individual oral assessment
The individual oral assessment is worth 25% and assesses productive, receptive and interactive skills. It includes a prepared presentation, a student-teacher discussion and a broader conversation connected to the course themes.
The starting stimulus differs by level:
| Level | Starting stimulus | Subsequent interaction |
|---|---|---|
| SL | A visual stimulus connected to a prescribed theme | Discussion of the stimulus, followed by a conversation including at least one additional course theme |
| HL | An extract from a literary work studied during the course | Discussion of the extract, followed by a conversation including at least one additional course theme |
At SL, description alone is not enough. Students should move from what can be seen to what the image suggests, how it relates to the relevant theme and what cultural or social perspectives it raises.
At HL, students must demonstrate understanding of the extract and its place within the literary work. The oral is still a Language B assessment rather than a Language A literary commentary, but supported interpretation and precise discussion of the extract are important.
For both levels, the conversation tests the ability to listen and respond spontaneously. Memorizing a complete speech is therefore less useful than practising how to clarify, justify, compare and extend an answer. Students can use the RevisionDojo Language B HL individual oral grader to structure self-review, while Jojo AI can generate unpredictable follow-up questions for rehearsal.
How the five prescribed themes shape assessment
All components draw on the same five prescribed themes:
- Identities
- Experiences
- Human ingenuity
- Social organization
- Sharing the planet
These themes provide contexts for communication rather than a fixed list of facts to memorize. The topics listed under them in IB documentation are optional recommended topics, not individually prescribed content that must all be examined.
Students should nevertheless build flexible thematic vocabulary and examples. A topic such as social media could connect to identities, human ingenuity or social organization depending on the question. The RevisionDojo Language B syllabus breakdown explains how to organize revision around these links rather than treating each theme as an isolated unit.
What is different at SL and HL?
The most visible differences are the Paper 1 word range and the oral stimulus. The deeper distinction is the expected proficiency.
| Feature | SL | HL |
|---|---|---|
| Paper 1 length | 250-400 words | 450-600 words |
| Paper 1 demand | Developed, appropriate communication | Greater complexity, range and nuance |
| Literary works | Not an assessment requirement stated for SL | Two works originally written in the target language |
| Oral stimulus | Visual stimulus | Extract from a studied literary work |
| Component weightings | 25% writing, 50% receptive skills, 25% oral | Same |
HL does not merely require an SL response with more words. Students need to sustain arguments, handle unfamiliar contexts, select more precise vocabulary and use complex structures without losing clarity.
Is this structure new for current exam students?
The 2029 subject brief is new, but the main assessment structure is not. Paper 1, Paper 2 and the individual oral keep the same overall weightings and core formats found in the course first assessed in 2020.
The date matters. Students sitting before the first 2029 assessment must follow the guide and instructions issued for their examination session, not assume that every detail in a future brief applies immediately. Schools receive the full subject guide and session-specific examination information through official IB channels.
The RevisionDojo explanation of the 2029 Language B syllabus compares the published structure with the current course. Always confirm administrative details and examination arrangements with your teacher or DP coordinator.
Common mistakes to avoid
- Choosing Paper 1 by topic alone: A familiar topic is not helpful if the required audience or text type is difficult to handle.
- Ignoring text-type conventions: Format and register are part of successful communication.
- Translating word for word: This often creates unnatural phrasing and prevents students from processing overall meaning.
- Treating Paper 2 as a vocabulary quiz: Context, tone, reference and structure are often more important than one unknown word.
- Only describing the SL visual: Strong oral responses interpret and connect it to wider issues.
- Reciting a memorized oral: Interaction requires genuine listening and adaptation.
- Assuming HL means only greater length: HL requires more sophisticated and nuanced communication.
A practical preparation plan
Use a weekly cycle that trains every weighted component:
- Write one Paper 1 response and revise it after feedback.
- Complete one focused listening exercise and record why each error occurred.
- Complete one reading set using textual evidence for every answer.
- Record one oral response, then repeat it with clearer development and fewer repeated errors.
- Review thematic vocabulary through active recall rather than rereading lists.
The RevisionDojo IB English B resource hub can support this routine with Questionbank practice, Study Notes and Flashcards. Mock Exams are useful once individual skills are secure because they reveal problems with pacing and concentration that short exercises may not show.
Conclusion
The new IB Language B assessment structure keeps a clear balance: 25% Paper 1 writing, 25% listening, 25% reading and 25% individual oral assessment. SL and HL share these weightings, while HL requires a longer written response, more sophisticated communication and an oral based on a studied literary extract.
Preparation should therefore be balanced across writing, listening, reading and speaking. RevisionDojo's Questionbank, Flashcards, Mock Exams and Jojo AI can help students build a regular practice cycle and identify which component needs the most attention.
