TOK Exhibition: Objects, Examples and Commentary Guide

The TOK exhibition is an individual IB Diploma assessment in which a dated bus ticket can support stronger analysis than a treasured family photograph. Learners choose one prescribed prompt, select three specific real-world or digital objects and write up to 950 words explaining how each object illuminates that prompt. The official task uses 35 prompts and is assessed as a single exhibition (IB, 2022).

In a sixth-form TOK lesson, display a named newspaper front page and an undated family photograph. Ask pairs, “Which object gives you more evidence for discussing bias, and why?” Learners produce two prompt-linked sentences identifying the usable context and evidence. This quick comparison establishes the central principle: personal meaning is not enough. The strongest object is the one whose specific context lets the learner make and justify a clear knowledge claim.

Specificity Beats Clever Symbolism

The examples below are planning aids created by teachers. They are not authenticated IB submissions, examiner comments or predicted marks. Use them to check whether each object is specific and fits the prompt, then refer to the official assessment instrument. In a sixth-form TOK lesson, ask pairs to underline the exact object detail that supports each claim and write one evidence-linked annotation for it.

For example, a specific archive photograph with contrasting captions can support a discussion of how source language, editorial choices and historical context shape knowledge. The value lies in the explicit link between that object and the selected prompt.

The difference isn't that one learner picked a rare object and the other picked a common one. The difference is specificity. The first learner chose an object, then hunted for a matching prompt. The second learner started with the prompt's knowledge question, then chose an object that directly illuminates it.

This article explains the official task, offers a practical prompt-first planning method and labels its examples as teacher-created. Use it alongside the current IB guide and the broader Theory of Knowledge teacher guide.

The 2022 TOK Exhibition Structure: What's Actually Being Assessed

Teaching for the current TOK course began in 2020, and the first assessment took place in 2022. The exhibition replaced the former presentation task. Plan from the current requirements: one prescribed prompt, three specific objects and one submitted file containing three object commentaries. This helps learners avoid outdated advice about separate assessment criteria.

You select one of 35 prescribed IA prompts and create an exhibition using three specific real-world objects, or images of objects. The single submitted file contains a commentary on each object, with a maximum of 950 words across all three.

The exhibition is assessed as a whole, using one assessment instrument, and receives a mark out of 10. It contributes one-third of the final TOK grade. The teacher marks the exhibition internally, and a sample goes through external moderation. Strong work identifies each object and its real-world context, links it to the selected prompt, explains its distinct contribution and supports points with evidence and clear prompt references.

The current assessment instrument uses one driving question and performance descriptors for the whole exhibition. It does not split the exhibition into separate A, B and C criteria. In a sixth-form standardisation activity, give teachers the same anonymous commentary and ask for one overall judgement. They should write notes based on the descriptors, rather than inventing three criterion scores.

‍

The Fatal Error: Choosing Your Object First

Object-first planning creates weak commentary. Learners often begin with “My phone is perfect for the modern world” or “My grandmother’s photo has special meaning”, then search for a prompt that appears to fit. Begin with the unchanged prompt instead, because personal attachment cannot substitute for a justified knowledge link.

Choosing an object first can lead to a forced or generic prompt link. Begin with a prescribed prompt, clarify what it asks, then choose objects whose specific contexts help explore it.

Here is a fictional teaching example. A learner links an iPhone to a prompt about intuition but explains only that the interface feels intuitive. The link remains weak because the object is not used to examine when intuition is or is not dependable.

In a sixth-form TOK lesson, the teacher displays a recorded chess position and asks, “What did the player choose before analysis, and what changed afterwards?” Learners produce a two-column comparison of the intuitive move and the computer-assisted review, then link that evidence to when trained intuition succeeds or fails.

The prompt-first process forces you to think logically. You're not decorating an object with philosophy; you're using an object to answer a knowledge question.

Use this checklist before you commit to an object:

• [ ] I have read the prompt's exact wording.
• [ ] I can articulate the knowledge question in my own words.
• [ ] I can explain which details from the object help explore the exact prescribed prompt.
• [ ] I have chosen an object that directly illuminates that question, not metaphorically, but evidentially.
• [ ] I can explain in one sentence why this object matters to this question.

If any box stays unchecked, you're not ready. Restart with a different object or a different prompt.

‍

A Practical Commentary Structure for Each Object

Plan each object commentary in four moves. First, identify the object and its context. Then link it to the prompt, explain its distinct contribution and support your points with evidence and references. These moves form a planning sequence, not four separate assessment criteria, so the final commentary should read as one connected argument.

Step 1: State and interpret the prescribed prompt.

State the prescribed prompt exactly, then explain the aspect your object will help explore. Keep the explanation tied to the wording of the prompt.

In a sixth-form TOK lesson, the teacher says, “Copy the prompt exactly, then circle the word your object helps you examine.” Learners produce a focused opening such as: “My prompt is ‘Is bias inevitable in the production of knowledge?’ This newspaper front page helps examine how editorial selection shapes the production of public knowledge.”

Step 2: Identify the object and its real-world context.

Identify the specific object, where and when it exists, and why that context matters to the prompt. Give enough precise detail for a reader to understand how the object functions as evidence.

Step 3: Explain and justify the object-prompt link.

Explain how details from the object support the link to the prompt and why this object makes a distinct contribution to the exhibition. Use relevant evidence and references for factual claims.

Step 4: Test the explanation where useful.

A relevant limitation or alternative interpretation can make an explanation stronger. It is optional and is not a separate assessment criterion. Include it only when it helps to show how the object contributes to the prompt.

Use the remaining words to make the object's context, evidence, prompt link or unique contribution clearer. The official examiner guidance does not advise adding a separate conclusion to each object commentary.

Critical Do-Nots: - Don't write as if the object is a symbol. Avoid "represents," "signifies," "embodies." - Don't assert claims without linking them to the object. - Don't assume the reader knows your prompt. Restate it. - Don't exceed 950 words. Rambling signals unclear thinking.

Teacher-Created Object Commentary Example

The following excerpt was created by a teacher and models one object. It is not a complete exhibition, authenticated learner work or examiner feedback. In a sixth-form TOK lesson, read it aloud and ask learners to label the context, prompt link, evidence and contribution, producing four annotations before they compare it with the official descriptors. A complete submission needs three objects linked to the same prompt.

Prescribed prompt: "What are the implications of having, or not having, knowledge?"

Learner's Object: A literacy primer from colonial India (early 20th century)

Learner's Commentary:

The prompt asks what happens when some people have access to knowledge but others do not. The object is a literacy primer that British administrators produced in colonial India to teach Indian learners to read and write in English.

The primer can help learners explore the effects of unequal access to language and institutional knowledge. English literacy could affect access to government jobs. At the same time, the text carried British cultural assumptions. The object therefore gives a clear context for examining who could use certain knowledge and what opportunities followed.

The effects did not go in only one direction. Some learners used English to read colonial law and express anti-colonial arguments. Access to the same knowledge could therefore support both administration and resistance.

The primer also raises questions about who selected the knowledge taught and which languages were treated as legitimate. That context helps justify the object's contribution to the prescribed prompt without claiming that the object proves a universal rule.

Teacher discussion prompt:

Discuss how clearly the excerpt identifies the object and its context. Check whether it links details from the object to the prescribed prompt and explains the object's distinct contribution. Apply the official descriptors to the whole exhibition rather than predicting a separate band for each criterion.

Why This Is Strong

• Uses the object as specific evidence, not vague symbolism.
• Engages with the knowledge question's tension (power for whom? in what direction?).
• Names limitations and alternative views.
• Explores different implications of access to knowledge rather than asserting one universal effect.

How It Could Be Stronger

This excerpt can be improved by making the prompt link and the object's distinct contribution more explicit. It remains only one part of a three-object exhibition.

‍

Five Questions to Ask Before You Submit

Use these five questions for a final desk check before submission. In a sixth-form TOK lesson, the teacher assigns one question to each peer reviewer and asks for evidence from the draft. Learners produce five brief annotations, each identifying a strength or a precise revision. Any unsupported “yes” becomes a rewrite task.

1. Have I used one prescribed IA prompt exactly as written for all three objects?
2. Have I identified the specific object and its real-world context clearly enough for the reader to understand its role?
3. Have I linked specific details from the object to the exact prescribed prompt and justified what this object contributes? If not, revise the explanation around object, context, prompt and evidence.
4. Have I justified this object's distinct contribution to the exhibition? Include a limitation or alternative interpretation only when it strengthens that justification.
5. Have I supported factual claims with appropriate evidence and references, then linked that evidence back to the prescribed prompt?

Object Ideas by Category, With What Makes Each One Work

Choose from these categories only after selecting the prompt. There is no universally best TOK exhibition prompt or object. A useful object has an identifiable real-world context, details the learner can examine and a contribution that differs from the other two objects. Treat every suggestion below as a starting point, not a ready-made answer.

In a sixth-form TOK lesson, give groups one object from each category and ask them to complete the sentence, “This specific object helps answer the prompt because…”. Learners produce a shortlist of three objects, each with a different claim, context and form of evidence. This prompt-first routine makes weak duplication visible before drafting begins.

‍

Personal and everyday objects

Personal meaning can help a learner explain context, but it does not earn credit by itself. A mundane public artefact often supports better analysis because the learner can step back from it and examine what counts as knowledge, evidence or justification.

• A learner’s dated bus ticket from a cancelled journey. Prompt: “What counts as good evidence for a claim?” The printed time, route and cancellation record create a verifiable context for comparing personal testimony with documentary evidence.
• A corrected Year 11 mathematics test. Prompt: “How can we know that current knowledge is an improvement upon past knowledge?” The original error, teacher annotation and later correction show a documented change in one learner’s reasoning.
• A specific recipe card altered by three generations. Prompt: “What is the relationship between personal experience and knowledge?” Handwritten substitutions connect embodied cooking experience with knowledge transmitted through a family.
• A pharmacy label issued for one named medicine. Prompt: “What role do experts play in influencing our consumption or acquisition of knowledge?” Its dosage instructions and authorised source show how expert knowledge reaches a user.

Why this fails: “My phone because it is important to me” names a broad object and an emotion, but supplies no event, record or knowledge problem to analyse.

‍

Historical and political objects

• A 1940 Ministry of Information poster displayed in a named local archive. Prompt: “What challenges are raised by the dissemination and/or communication of knowledge?” Its intended audience, wording and wartime distribution provide evidence about controlled public information.
• A marked ballot paper reproduced in a council election guide. Prompt: “Who owns knowledge?” Its official source and rules let the learner examine who controls valid knowledge of electoral intent.
• Two captions attached to the same 1989 press photograph. Prompt: “Is bias inevitable in the production of knowledge?” The named publications and contrasting captions expose editorial selection within one event.
• A school history textbook map printed before a border change. Prompt: “How is current knowledge shaped by its historical development?” The edition date and superseded boundary make changing political classification visible.

Why this fails: “An old photograph representing history” lacks a date, creator, audience and documented use, so the learner has little beyond description.

‍

Artistic and creative objects

• A censored programme from a named school production. Prompt: “In what ways do values affect the production of knowledge?” The removed lines and recorded decision give the learner evidence about institutional values shaping expression.
• A preparatory sketch beside the completed portrait. Prompt: “What role does imagination play in producing knowledge about the world?” The visible changes reveal choices made while translating observation into an image.
• A museum label revised after a repatriation dispute. Prompt: “Does some knowledge belong only to particular communities of knowers?” The two versions show how authority and community knowledge changed the object’s interpretation.
• A recording of one improvised passage from a school jazz concert. Prompt: “Are some types of knowledge less open to interpretation than others?” The named performance connects musical notation, performer knowledge and audience interpretation.

Why this fails: “A painting that signifies creativity” treats the art as a symbol. It gives no specific history of how it was made, interpretation or decision to explore.

‍

Scientific and technological objects

Use scientific and technological objects to explore how instruments, models and classifications shape claims. Choose a specific object. “A biology textbook” or “a microscope” is too broad.

• A lateral-flow test used on a recorded date. Prompt: “To what extent is certainty attainable?” Its instructions, visible result and known decision threshold support analysis of probabilistic evidence.
• A weather app forecast saved before a cancelled sports day. Prompt: “What features of knowledge have an impact on its reliability?” The location, timestamp and later weather record allow comparison between prediction and observation.
• A labelled microscope slide from a sixth-form practical. Prompt: “How important are material tools in the production or acquisition of knowledge?” The preparation method and magnification show how an instrument makes particular observations possible.
• A reclassified specimen label in a natural-history collection. Prompt: “How does the way that we organise or classify knowledge affect what we know?” The old and new taxonomic names document a changed scientific classification.

Why this fails: “A microscope because science uses technology” only names a category and states a general fact. It does not describe a specific observation made with an instrument that can be traced.

‍

Digital and media objects

Digital objects count when the learner can identify the exact file, post, output or interaction. They must also preserve its context. Synthetic media are useful only when the commentary explores how people made or shared them, or whether they can serve as evidence. It should not simply treat artificial intelligence as the topic.

• A screenshot of a deleted post with its date, account and archived URL. Prompt: “What counts as good evidence for a claim?” The preserved metadata and deletion create a specific problem of verification.
• A false answer produced by a named language model from a saved prompt. Prompt: “What constitutes a good justification for a claim?” The exact prompt, output and checked sources let the learner separate fluent explanation from justified knowledge.
• A deepfake clip circulated during a documented election campaign. Prompt: “How can we distinguish between knowledge, belief and opinion?” Its origin and circulation history support analysis of apparent audiovisual evidence.
• A synthetic dataset used in a school computing project. Prompt: “Are some types of knowledge more useful than others?” Its generation rules and comparison with real records expose gains in privacy alongside losses in representativeness.

Why this fails: “Social media spreads misinformation” is a broad topic. Without one saved post, named source and documented circulation context, there is no object to examine through critical thinking.

‍

The Three Questions Learners Ask About Objects

Most object-selection problems reduce to specificity, subject relevance and boundaries. Resolve these before learners draft. In a sixth-form TOK lesson, the teacher displays a screenshot, a chemistry practical record and a marked novel, then asks groups to approve or reject each object. Learners produce one decision and one context-based justification for each.

‍

Can a digital object count?

Yes. A particular post, screenshot, model output, digital photograph or data file can count when its creator, date, use and real-world setting are identifiable. “TikTok” is a platform, not an object. A saved video posted by a named account during a documented event is specific enough to analyse.

‍

Do objects have to relate to the learner’s own subjects?

No. The object must serve the chosen prompt, not match an examination subject. Subject knowledge can help establish context, but it cannot replace the TOK link. A learner taking history can use a medical consent form if they can explain its context and particular contribution to the prompt.

‍

Does a book count as one object or several?

A specific physical copy or edition can count as one object. Its separate chapters do not automatically become separate objects. If a particular annotated page matters, identify that page and explain its real-world use. Avoid using three passages from one book when they repeat the same context or knowledge claim.

‍

Limitations and Critiques

An object idea is not automatically suitable for a TOK exhibition. Its value depends on three things: a specific real-world context, a justified link to the learner’s unchanged chosen prompt and a particular contribution that the other two objects do not already make. A clever object cannot rescue a generic explanation. Equally, an ordinary receipt can work when its date, use and evidential role are clear.

In a sixth-form TOK lesson, give learners the suggestion “family photograph” and ask them to test two versions. The teacher says, “Name the photograph, the event, who used it and the exact prompt link.” Learners reject the generic version and produce a contextualised alternative, such as a photograph whose caption was changed in a local archive. They then explain what this object contributes that a newspaper report would not.

Examples are planning aids, not templates to copy. Copying an object, prompt link or commentary structure without its original context usually leads to description rather than analysis. Check personal and emotionally meaningful objects with particular care, as attachment can lead learners to tell the object’s story instead of examining a knowledge problem. Use each example to raise questions, then ask the learner to defend their final choice in their own words.
