How DP Language B Is Assessed: Revision Notes

Condensed for quick recall of how the course is assessed. For the full subject overview, use the IB DP Language B subject overview, and for a paper-by-paper exam-day plan see the exam preparation guide.

Ab initio as a third option

For students with no prior background in the target language at all, some schools instead offer Language ab initio rather than Language B – a separate course with its own, more foundational assessment structure. Language B itself is intended for students who already bring some prior experience of the target language, so confirming which of the two courses your school has entered you for is worth checking explicitly, since the assessment structures, required vocabulary range and oral formats differ between them.

Same weightings at SL and HL — but not the same durations

The percentage weightings below are identical at SL and HL. The durations are not — four concrete timings differ between the levels, so do not time your practice as if the two levels sat the same papers for the same length of time.

Component	Weight	Raw marks	Duration (SL)	Duration (HL)
Paper 1 (productive writing, choice of tasks)	25%	–	1 hour 15 minutes (250-400 words)	1 hour 30 minutes (450-600 words)
Paper 2 – listening	25%	25	45 minutes	1 hour
Paper 2 – reading	25%	40	1 hour (same at both levels)	1 hour (same at both levels)
Individual oral (recorded by your own teacher)	25%	–	15 minutes’ preparation	20 minutes’ preparation

Two things to note from this table: first, Paper 2’s 25%/25% weighting split between listening and reading is even, but the raw marks are not (25 for listening vs 40 for reading), so reading is nearly two-thirds of the paper by raw marks – budget practice time accordingly, not by the weighting split alone. Second, of the four timings that differ between SL and HL, total external assessment time (Paper 1 + Paper 2), Paper 1’s own duration, and the individual oral’s preparation time all increase at HL, while Paper 2’s reading section stays fixed at one hour for both levels – only its listening section gets longer at HL, so don’t assume all of Paper 2 lengthens uniformly. Recommended teaching time is 150 hours at SL and 240 hours at HL.

SL vs HL — what actually differs

• HL only: study of two literary works originally written in the target language.
• HL students are expected to extend the range and complexity of language used/understood.
• HL individual oral: built around an extract from one of the two literary works, connected to a broader theme.
• SL individual oral: based on a photograph or short stimulus connected to one of the five prescribed themes (identities, experiences, human ingenuity, social organization, sharing the planet).

The individual oral in more depth

The oral is marked against four criteria: Criterion A, language (12 marks); Criterion B1, message (6 marks), which is Message—visual stimulus at SL and Message—literary extract at HL; Criterion B2, message—conversation (6 marks); and Criterion C, interactive skills—communication (6 marks), for a total of 30. The presentation on the stimulus or extract and the follow-up conversation are marked separately (B1 and B2), and interactive skills are a fifth of the marks. A common weakness at both levels is spending too much of the prepared time describing the surface content of the stimulus or extract, leaving too little time to develop an argument or connect it to the broader theme – examiners consistently reward students who move beyond description into interpretation and connection within the time available.

Command terms and the two papers

Paper 1’s productive writing task is assessed against text-type conventions (for example, the register and structure expected of a formal letter versus an informal blog post) as much as against grammatical accuracy – choosing a text type that doesn’t match the task’s purpose or audience loses marks even when the language itself is correct. Paper 2’s listening and reading comprehension exercises are more variable in question format across the different target languages this course covers, but consistently test detailed understanding rather than only gist – skimming a passage for general meaning is not sufficient preparation; practice should include locating and extracting specific detail under timed conditions.

Why SL and HL share weightings but differ in demand

Unlike some DP subjects where SL and HL differ in which components are assessed, Language B keeps an identical percentage structure across both levels – what changes is the complexity and range of language used and understood, the number of literary works studied (two at HL, none required at SL, though schools may still choose to include literary material at SL), the format of the individual oral, and (see the duration column above) how long each component actually takes. This means a Language B revision plan built around the weightings above transfers directly between levels for how much each component is worth; but timed practice needs the actual HL or SL duration for each component, since the papers themselves are not the same length across levels.

How this compares to Language A courses

Language B is studied as an additional, typically non-native language, whereas the two Language A courses (Language and Literature, and Literature) are studied in a student’s best language, usually their native or most fluent one. This distinction shapes assessment design directly: Language B’s Paper 1 and Paper 2 test productive and receptive skill in a language still being actively acquired, while Language A’s assessment (a wider Paper 1/Paper 2 split, an HL essay, and a differently structured oral) assumes near-native fluency and instead tests literary and textual analysis at a more sophisticated level.

Exam traps

• Preparing for the oral using the wrong format for your level (photograph/stimulus at SL, literary extract at HL).
• Underpreparing Paper 2, since it’s worth 50% — half the total grade — and budgeting practice time by the even 25%/25% weighting split rather than the raw marks, which favour reading (40 marks) over listening (25 marks).
• HL students not building familiarity with both required literary works before the oral.

Self-test

1. What is Paper 2 worth, and how is it split?
2. What’s required only at HL, not SL?
3. What is the SL individual oral based on?
4. Who conducts and records the individual oral?
5. Name one criterion the individual oral is graded against, beyond language accuracy.
6. How many literary works are required to be studied at HL?

Answers: 1. 50%, split evenly by weighting between listening comprehension (25%, 25 raw marks) and reading comprehension (25%, 40 raw marks) – the weighting is even but the raw marks are not. 2. Study of two literary works originally written in the target language. 3. A photograph or short stimulus connected to one of the five prescribed themes. 4. The student’s own teacher. 5. Any one of: Criterion B1, message (visual stimulus at SL, literary extract at HL); Criterion B2, message—conversation; Criterion C, interactive skills—communication. 6. Two.
