Theory of Knowledge Handbook

The TOK course provides students with an opportunity to explore and reflect on the nature of knowledge and the process of knowing. It is a core element of the DP to which schools are required to devote at least 100 hours of class time.

In TOK, students reflect on the knowledge, beliefs and opinions that they have built up from their years of academic studies and their lives outside the classroom. The course is intended to be challenging and thought-provoking—as well as empowering—for students.

The course centres on the exploration of knowledge questions, which are a key tool for both teachers and students. These are contestable questions about knowledge itself, such as: “What counts as good evidence for a claim?”, “Are some types of knowledge less open to interpretation than others?”, or “What constraints should there be on the pursuit of knowledge?”. While these questions may initially seem slightly intimidating, they become much more accessible when considered with reference to specific examples within the TOK course.

The TOK curriculum is made up of three deeply interconnected parts.

  • The core theme—Knowledge and the knower: This theme encourages students to reflect on themselves as knowers and thinkers, and to consider the different communities of knowers to which we belong.

  • Optional themes: This element provides an opportunity to take a more in-depth look at two themes of particular interest to teachers and students. The given themes all have a significant impact on the world today and play a key role in shaping people’s perspectives and identities. Teachers select two optional themes from a choice of five: knowledge and technology; knowledge and language; knowledge and politics; knowledge and religion; and knowledge and indigenous societies.

  • Areas of knowledge: The areas of knowledge (AOK) are specific branches of knowledge, each of which can be seen to have a distinct nature and sometimes use different methods of gaining knowledge. In TOK, students explore five compulsory areas of knowledge: history; the human sciences; the natural sciences; mathematics; and the arts.

To help teachers and students explore these three parts of the TOK curriculum, guidance and suggested knowledge questions are provided. These suggested knowledge questions are organized into a framework of four elements: scope, perspectives, methods and tools, and ethics. This "knowledge framework" encourages a deep exploration of each theme and AOK. Having these common elements run throughout the different parts of the curriculum also helps to unify the course and helps students to make effective connections and comparisons across the different themes and areas of knowledge.

There are two assessment tasks in the TOK course.

  • The TOK exhibition assesses the ability of the student to show how TOK manifests in the world around us. The exhibition is an internal assessment component; it is marked by the teacher and is externally moderated by the IB.

  • The TOK essay engages students in a more formal and sustained piece of writing in response to a title focused on the areas of knowledge. The essay is an external assessment component; it is marked by IB examiners. The essay must be a maximum of 1,600 words and must be on one of the six prescribed titles issued by the IB for each examination session.

Course Outline

The TOK exhibition

The TOK exhibition explores how TOK manifests in the world around us. For this reason it is strongly recommended that students base their exhibition on one of the TOK themes (either the core theme or one of the optional themes).

The TOK exhibition is an internal assessment component—it is marked by the teacher and is externally moderated by the IB. Internal assessment is an integral part of all DP courses. It enables students to demonstrate the application of their skills and knowledge, and to pursue their personal interests.

For this task, students are required to create an exhibition of three objects that connect to one of the 35 “IA prompts” provided in the “IA prompts” section of this guide. Students must select just one IA prompt on which to base their exhibition, and all three objects must be linked to the same IA prompt.

Students are required to create an exhibition comprising three objects, or images of objects, and an accompanying written commentary on each object. To enable their exhibition to be marked by their TOK teacher and for samples of student work to be submitted to the IB for moderation, students are required to produce a single file containing:

  • a title clearly indicating their selected IA prompt

  • images of their three objects

  • a typed commentary on each object that identifies each object and its specific real-world context, justifies its inclusion in the exhibition and links to the IA prompt (maximum 950 words)

  • appropriate citations and references.

Each student must create an individual exhibition. Group work may not be undertaken by students. Multiple students in the same TOK class are permitted to create exhibitions on the same IA prompt. However, students in the same class are not permitted to use any of the same objects.

The TOK exhibition task has been explicitly designed to be completed during the first year of the DP. To support DP students, it is important that schools have a clear overall schedule of internal deadlines for the completion of the internal assessment tasks for the different subjects. Within this schedule, teachers are strongly encouraged to complete the TOK exhibition in the first year of the programme.

TOK essay on a prescribed title

The TOK essay engages students in a formal, sustained piece of writing in response to one of the six titles that are prescribed by the IB for each examination session. These titles take the form of knowledge questions that are focused on the areas of knowledge.

The TOK essay is an external assessment component. Each student’s essay is submitted to the IB to be marked by IB examiners. The TOK Essay must be written in standard 12 type size and be double spaced. It is not primarily a research paper, but it is expected that specific sources will be used, and these must be acknowledged.

Essay titles

It is not intended that students will spend six months working on their essays—teachers should select a window within that six-month period for students to work on their essays that fits with the other commitments in their school calendars. It is suggested that 10 hours of teaching time should be dedicated to working on the TOK Essay.

The chosen title must be used exactly as given; it must not be altered in any way.

  • If the title has been modified but it is still clear which prescribed title for the current session it refers to, the essay will be marked against that prescribed title. Any lack of relevance in the student’s response to the prescribed title arising from this modification will be reflected in the score awarded.

  • If it is clear that the title bears no resemblance to any title for the current session, the essay will be awarded a score of zero, in accordance with the TOK essay assessment instrument.

Word count

The maximum length of the essay is 1,600 words. Extended footnotes or appendices are not appropriate for the TOK essay.

The word count includes:

  • the main part of the essay

  • any quotations.

The word count does not include:

  • any acknowledgments

  • the references (whether given in footnotes, endnotes or in-text) and bibliography

  • any maps, charts, diagrams, annotated illustrations or tables.

If an essay exceeds the word limit, then examiners are instructed to stop reading after 1,600 words and to base their assessment on just the first 1,600 words. Students are required to indicate the number of words when the essay is uploaded during the submission process.
