IB Language B Individual Oral: Format, Criteria and Preparation

How the IB Language B individual oral works at SL and HL: preparation time, the three timed parts, the 30-mark rubric, and how to prepare for a visual stimulus or literary extract.

Trusted by IB students

Quick Answer

The IB Language B individual oral is a 12 to 15 minute conversation with your teacher, marked out of 30 and worth 25% of your grade at SL and HL. At SL you prepare a visual stimulus for 15 minutes; at HL, a literary extract for 20 minutes. You present for 3 to 4 minutes, discuss for 4 to 5, then hold a 5 to 6 minute general conversation.

What You'll Learn

  • Worth 25% of your Language B grade at SL and HL, marked out of 30
  • SL: choose one of two visual stimuli, with 15 minutes of supervised preparation
  • HL: choose one of two literary extracts from the works you studied, with 20 minutes of preparation
  • Three parts: presentation (3 to 4 minutes), follow-up discussion (4 to 5), general conversation (5 to 6)
  • Language is worth 12 of the 30 marks; what you say and how you interact earn the other 18

How the Language B Individual Oral Works

The individual oral is the internal assessment for every Language B course, from English B to Spanish B or Mandarin B. It is a conversation with your teacher in the target language, based on a stimulus you prepare under supervision. Your teacher conducts, records and marks it, and the IB moderates a sample of recordings from each school. The structure is the same at SL and HL; what changes is the stimulus and the preparation time. The course is built around five prescribed themes, and the oral draws on them: identities, experiences, human ingenuity, social organisation and sharing the planet.

  • Preparation: 15 minutes at SL or 20 minutes at HL, supervised, in which you choose one of two stimuli
  • Notes: you may make brief working notes during preparation, up to 10 bullet points, and use them for reference
  • Part 1, presentation: 3 to 4 minutes on your chosen stimulus
  • Part 2, follow-up discussion: 4 to 5 minutes with your teacher, building on your presentation
  • Part 3, general conversation: 5 to 6 minutes on course themes; at SL this includes at least one theme beyond the one in your stimulus
  • Total: 12 to 15 minutes, marked out of 30, worth 25% of your final grade at both levels

Pro Tip

Because the general conversation moves on to other themes, you need vocabulary, examples and opinions ready for all five themes, not only the ones you enjoy.

SL vs HL: Visual Stimulus or Literary Extract

At SL, you are shown two visual stimuli, usually a photograph, poster or similar image, and you choose one. Each is clearly linked to one or more course themes, and your presentation should describe it, connect it to its theme and relate it to the culture or cultures where the language is spoken. At HL, you are given two extracts of up to about 300 words, one from each of the two literary works you studied in the target language, and you choose one. Your presentation discusses the extract: what happens, the characters and ideas, and how it connects to the work as a whole.

  • SL stimulus: a visual image linked to a course theme, which you have not seen before
  • SL focus: describe, interpret, connect to the theme and to target-language culture, and give a justified personal response
  • HL stimulus: a literary extract from one of your two studied works; you do not know in advance which passages will appear
  • HL focus: place the extract in the work, explain events, characters and ideas, give your interpretation and link it to course themes
  • Both levels: the follow-up discussion builds on your presentation, and the general conversation moves beyond it

Pro Tip

At HL you cannot predict the passage, so know both works well enough to place any page: a timeline of key events, a character map and three or four ideas per work that you can discuss in the target language.

Structuring Your 3 to 4 Minute Presentation

A clear shape helps you sound confident and fills the time without padding. For example, an SL student shown a photograph of a busy city cycle lane might name the sharing the planet theme, describe the scene, compare cycling policy in a country where the language is spoken with their own country, and end by asking whether cities should close their centres to cars. Adapt this order to your stimulus:

  1. 1Introduce the stimulus in one or two sentences: what the image shows (SL) or where the extract sits in the work (HL)
  2. 2Name the theme it connects to and the main message or idea you see in it
  3. 3Develop two or three points with detail from the stimulus: people, setting, text and symbols (SL), or events, characters and language (HL)
  4. 4Connect to the wider picture: a target-language culture you know about (SL) or the work as a whole (HL)
  5. 5Give and justify a personal response, then finish with a point or question that opens up the discussion

Language B Oral Criteria: The 30-Mark Rubric

Your teacher marks the oral against four criteria. Language carries the most marks, but more than half of the total rewards what you say and how well you interact.

  • Criterion A, Language (12 marks): the range and accuracy of your vocabulary and grammar, and how clear your pronunciation and intonation are
  • Criterion B1, Message (6 marks): how relevant and well developed your presentation is, based on the visual stimulus at SL or the literary extract at HL
  • Criterion B2, Message, conversation (6 marks): how relevant and well developed your answers are in the follow-up discussion and the general conversation
  • Criterion C, Interactive skills, communication (6 marks): how well you understand your teacher, keep the conversation going and contribute ideas of your own

Pro Tip

Criterion C rewards independent contributions. Adding an example nobody asked for, or turning a question back to your teacher, shows you are taking part in a conversation rather than just answering.

How to Prepare in the Weeks Before

The oral tests what you can say spontaneously, so most of your preparation should be speaking, organised by theme.

  • Build vocabulary by theme, including words for describing images, such as foreground, background, mood, gesture and slogan
  • Collect two or three concrete cultural examples per theme from places where the language is spoken, such as a festival, a policy, a news story or a well-known person
  • Learn phrases for giving opinions, comparing, speculating and concluding, and practise using them in full answers
  • Practise with unseen images (SL) or random passages from your works (HL) under a 15 or 20 minute timer
  • Record yourself, listen back and note repeated errors to fix
  • Hold regular short conversations on all five themes, with classmates, a tutor or a language partner
  • At HL, reread both works and practise summarising any chapter in the target language in one minute

Using Your 15 or 20 Minutes of Preparation

The preparation time is short, so go in with a routine:

  1. 1Look at both stimuli and decide within a minute or two. Pick the one you can say most about, not the one you like most
  2. 2Brainstorm what you see or what happens, the theme, cultural links and your opinion
  3. 3Turn the best ideas into your bullet points in presentation order, using keywords only
  4. 4Note a few precise words or phrases you want to use, especially any you tend to forget under pressure
  5. 5Predict two or three follow-up questions and think of an example for each

Watch Out

Your notes are brief working notes for reference. Writing out sentences to read aloud costs you preparation time and usually costs marks in the oral too.

During the Oral: Techniques That Score

These habits help in every part of the oral:

  • Extend every answer: make a point, give a reason, add an example, then a consequence or comparison
  • If you do not understand a question, ask for clarification in the target language
  • Use natural fillers while you think, rather than silence or switching language
  • Self-correct quickly and keep going; a small slip matters less than a stalled answer
  • Paraphrase when you forget a word: describe it rather than stopping
  • Link back to target-language culture when it is relevant
  • React to your teacher's comments and add your own ideas, so it feels like a real conversation

Pro Tip

Your teacher marks communication, not perfection. An answer with minor errors that communicates ideas clearly and develops them scores better than a short, careful answer that avoids risk.

Common Mistakes in the Language B Oral

These are the habits that most often pull marks down:

  • Memorising a presentation in advance and forcing it onto whatever stimulus appears
  • Describing the image without interpreting it or connecting it to a theme
  • At SL, making no link to a target-language culture
  • At HL, retelling the plot instead of discussing characters and ideas
  • Giving one-sentence answers in the discussion
  • Preparing only one or two themes for the general conversation
  • Freezing after an error instead of rephrasing

Frequently Asked Questions

The oral itself lasts 12 to 15 minutes: a 3 to 4 minute presentation, a 4 to 5 minute follow-up discussion and a 5 to 6 minute general conversation. Before it you have supervised preparation time, 15 minutes at SL and 20 minutes at HL. The structure is the same whichever language you study, from English B to Spanish B.

The stimulus. At SL you choose one of two visual stimuli linked to the course themes and relate it to target-language culture. At HL you choose one of two literary extracts of up to about 300 words, one from each of the two works you studied, and discuss it. HL students get 20 minutes of preparation instead of 15 and are expected to use more complex language.

It is marked out of 30 against four criteria: A, language (12 marks); B1, message in the presentation (6 marks); B2, message in the discussion and conversation (6 marks); and C, interactive skills (6 marks). Your teacher marks it, the IB moderates a sample from your school, and the oral counts for 25% of your final grade at SL and HL.

Only the notes you make during your supervised preparation time. You can write brief working notes of up to 10 bullet points and use them for reference while you speak. You cannot bring in notes prepared beforehand, and your notes should be keywords and prompts, not sentences to read aloud.

No. The global issue belongs to the Language A individual oral, such as the English A IO, where you compare two works you studied. The Language B oral is built around the five prescribed themes instead: identities, experiences, human ingenuity, social organisation and sharing the planet. Your stimulus links to a theme, and the general conversation moves on to other themes.

A new Language B guide starts teaching in August 2027, with first exams in May 2029. The IB's subject brief for it keeps the oral at 25% of the grade, with a visual stimulus at SL, a literary extract at HL, a discussion, and a conversation that includes at least one more theme. The IB says the oral is unchanged in format and weighting; only the wording of the descriptors for criteria B2 and C is revised. The full guide is due in February 2027. If you sit exams in 2026, 2027 or 2028, the current rules on this page apply.

Paraphrase or describe what you mean, then keep going. Saying 'the place where you buy medicine' if you forget 'pharmacy' is a natural communication strategy, and it shows the control that the language and interaction criteria reward. Stopping completely, or switching to another language, does more damage than an imperfect description.
