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.
