Quick answer: Choose three specific, pre-existing objects that all connect to one unchanged official TOK IA prompt. For each object, identify its real-world context, explain a precise link to the prompt, justify the distinct contribution it makes and support the claims with evidence. The 950-word maximum covers all three commentaries combined.
TOK exhibition requirements at a glance
| Requirement | Current official rule |
|---|---|
| Prompt | Select one of the 35 official IA prompts and use its wording unchanged |
| Objects | Three specific objects, or images of objects, all linked to the same prompt |
| Context | Each object needs a specific real-world time and place, including virtual spaces where relevant |
| Commentary | Identify and contextualise each object, explain its prompt link and justify its inclusion |
| Word limit | 950 words across all three written commentaries, not 950 words each |
| Submission | One file with the prompt as title, three images, commentaries, citations and references |
| Assessment | Internally assessed by the teacher and externally moderated by the IB |
| Weighting | One third, or 33%, of the TOK assessment |
The exhibition is marked holistically out of 10. It is not three separately totalled mini-criteria, and a decorative physical display is not what the submitted commentary is assessed on.
Start with the prompt, not a list of impressive objects
The official IA prompts are stable for the life of the current guide rather than changing each examination session. Select one prompt exactly as published and use it as the exhibition title. All three objects must explore that same question.
Before choosing objects, unpack the prompt without rewriting it:
- Identify its central knowledge issue, such as evidence, certainty, values, power, interpretation or responsibility.
- Define any important term provisionally; do not assume every word has one uncontested meaning.
- List two or three ways the issue can manifest in the world.
- Look for specific objects whose real histories make those differences visible.
If a student invents a new question that is not one of the official prompts, the assessment instrument provides for a mark of zero. A slightly altered prompt can also reduce relevance even when the original remains recognisable. Copy the selected wording carefully from the current guide or school materials.
What counts as a TOK exhibition object?
The IB takes a deliberately broad view of object type. An object may be physical or digital, and a student can use an image when the physical item cannot practically be displayed. A student-created object is possible when it already existed for a real purpose; it cannot be manufactured solely to illustrate the exhibition.
The decisive distinction is specific versus generic.
| Too generic | Made specific by real-world context |
|---|---|
| A newspaper | A named issue published on a stated date in response to a documented event |
| A scientific model | A particular model used by a named research group for a known purpose |
| A social-media post | A particular post, from a stated account and date, situated in the exchange where it appeared |
| A school rule | The version of a named policy that operated at a particular school and time |
| A photograph | A particular image with a known maker, subject, date, use and circulation context |
Specificity is not just adding a brand name. The commentary should give enough context for a reader to understand where the object exists, what it did, who used or encountered it and why that history matters to the knowledge question.
A five-test object selection method
1. The identification test
Can the object be identified precisely in one or two sentences? Record the name or description, creator or owner where relevant, date, location or platform, and the real event or practice in which it operated.
If the description still fits thousands of interchangeable objects, the selection is probably too generic.
2. The prompt-link test
Complete this sentence with an arguable knowledge claim:
This object helps answer the prompt because its real-world use shows that …
The sentence should explain a relationship, tension or consequence. “This relates to knowledge” and repeated definitions do not show how TOK manifests in the world.
3. The contribution test
Ask why this particular object is needed when the other two are already present. A useful set might expose different mechanisms, contexts, perspectives, limits or consequences. Diversity is valuable only when it advances the exploration; there is no official rule that the objects must represent three different themes or areas of knowledge.
Write a one-sentence contribution for every candidate. If two sentences make the same point with different nouns, replace or reconceive one object.
4. The evidence test
List the evidence needed to support the contextual and interpretive claims. This may include the object's creator or provenance, publication context, documented use, an authoritative account of the event, or a reliable explanation of the relevant knowledge practice.
The object is not automatically evidence for every claim made about it. Cite the original or most authoritative available source, acknowledge the image, and distinguish documented facts from the student's interpretation.
5. The 950-word test
Sketch the context, link, contribution and evidence for all three objects before writing prose. If one object needs most of the word allowance merely to explain its background, the context may be too complicated. If it produces only a generic sentence, it may be too shallow.
Do not reserve exactly one third of the words by force. The final exhibition is assessed as a whole, but each object still needs clear treatment.
Build each commentary around the assessment demand
The official assessment instrument asks one driving question: whether the exhibition successfully shows how TOK manifests in the world around us. A practical drafting sequence for each object is:
Identify and contextualise
Name the exact object and establish the time, place and real-world situation that make it specific. Include only background that the later analysis uses.
Explain the link to the prompt
Make a focused knowledge claim and show how features of the object's context support it. Return explicitly to the wording of the selected prompt rather than discussing a loosely related TOK concept.
Justify this object's contribution
Explain what becomes visible through this object that the exhibition would otherwise miss. This is stronger than claiming the object is interesting, famous, unusual or personally important.
Support the points
Use relevant evidence and references for factual claims and provenance. Then show the reasoning that connects that evidence to the knowledge question. A citation does not replace explanation.
The sequence is a reasoning check, not an official paragraph template. A clear commentary may integrate these moves in a different order.
What the top assessment band actually rewards
The published top-band description centres on four connected qualities:
- three objects and their specific real-world contexts are clearly identified;
- links between every object and the selected prompt are clear and well explained;
- the particular contribution of each object is strongly justified; and
- points are supported by appropriate evidence and explicit references to the prompt.
The assessment uses global-impression marking. Treat these as connected qualities of the complete exhibition, not boxes that mechanically earn separate marks.
Common myths and avoidable mistakes
“Every object must be personally meaningful”
Personal experience can supply valuable context, but personal meaning is not a separate requirement in the assessment instrument. A personal story that does not establish a precise object-to-prompt link remains descriptive.
“The three objects must come from different domains”
There is no such universal rule. The set should avoid repetition and each object should make a distinct contribution, but forcing artificial variety can weaken a coherent exploration.
“Every object needs an area of knowledge”
The current examiner guidance says areas of knowledge are not expected or assessed in the exhibition. Themes can help a student focus, but examiners should not require or score them either.
“A symbolic stock image is enough”
Generic images and objects used only to stand for an abstract idea are difficult to place in a specific real-world context. Select the actual object whose history does analytical work.
“An introduction and conclusion are compulsory”
They are not. With a 950-word maximum, use an introduction or conclusion only when it adds analysis that the three object commentaries need.
“The display itself earns the mark”
Schools provide an opportunity to showcase completed exhibitions, but that event is not part of the formal assessment task. The submitted file and its object commentaries are the assessable evidence.
Final submission audit
- The title reproduces one official IA prompt without changing its wording.
- Exactly three specific objects are used and all answer the same prompt.
- Every image clearly corresponds to the object discussed and is appropriately acknowledged.
- Every commentary states a specific real-world context.
- Every commentary explains, rather than merely asserts, its link to the prompt.
- Each object's distinct contribution is justified without repeating the other two.
- Factual claims, borrowed ideas and images have appropriate citations and references.
- The combined commentary is no more than 950 words; extended footnotes and appendices are not used to hide analysis.
- The work remains the student's own, and teacher or AI assistance follows the school's rules.
The teacher may advise on one draft but should not edit it. Keep planning notes and source records so the student can explain the choices and demonstrate authentic authorship.

IB TOK exhibition object FAQs
How many objects are required for the TOK exhibition?
The exhibition requires three specific objects, or images of objects. All three must connect to the same one of the 35 official IA prompts. The submitted file also includes the prompt as its title, the object images, commentaries and appropriate citations and references.
Can a TOK exhibition object be digital?
Yes. The official guide permits digital objects and images of physical objects that cannot practically be exhibited. A digital object must still be a specific, pre-existing object situated in a particular real-world time and place, including a virtual space; it should not be created only for the exhibition.
Is the TOK exhibition word limit 950 words per object?
No. The maximum is 950 words across the written commentaries for all three objects combined. Text within the objects, acknowledgements, references and the bibliography are excluded. Examiners stop reading after 950 words, and extended footnotes or appendices are not appropriate.
Do TOK exhibition objects have to come from different themes or areas of knowledge?
No. The guide encourages using a TOK theme as a possible way to focus the exhibition, but the examiner instructions say a theme is not required by the assessment instrument and areas of knowledge are not expected or assessed. Choose objects for their distinct contribution to the selected prompt, not to fill three artificial categories.
What makes a strong TOK exhibition object?
A strong choice is a specific object with a clearly identified real-world context that lets the student make a precise, evidence-supported link to the selected prompt. The commentary must also justify the particular contribution that object makes; describing the object or saying it is personally meaningful is not enough.
Does a TOK exhibition need an introduction and conclusion?
No. The current examiner instructions state that an introduction and conclusion are not required. With only 950 words, prioritise identification and context, the object-to-prompt link, justification of each object's contribution, and supporting evidence.
