IB TOK Essay Tips
The TOK essay is marked based on the student's ability to demonstrate an understanding of the subject, use critical thinking skills to evaluate various perspectives, and apply TOK concepts to real-life scenarios. Students should therefore:
- Demonstrate an in-depth understanding of knowledge questions
- Provide balanced arguments by critically analysing assumptions, incorporating counterarguments, and applying real-life examples
- Consider different perspectives
- Ensure clarity and coherence in their writing
Here's a suggested approach to the essay:
- Understand the Prescribed Title: Clarify key terms and concepts.
- Identify Relevant AOKs: Choose appropriate AOKs to frame the discussion.
- Develop Knowledge Questions: Formulate open-ended questions that guide the exploration of the title.
- Gather Real-Life Examples: Use relevant examples to support arguments.
- Create an Outline: Organise the essay with a clear introduction, body paragraphs for each argument, and a conclusion.
- Draft and Revise: Write the essay, seek feedback, and refine the content for coherence and depth.
Remember, the TOK essay is not a research paper, but rather an opportunity to reflect and analyse on the knowledge questions at hand. Nonetheless, you should properly cite the sources and cite widely. When in doubt, don't hesitate to seek help from teachers or IB TOK Tutors!

How much will my teacher help?
Teachers play an important role in guiding and supporting students throughout the TOK essay writing process. They are responsible for explaining the task requirements and assessment criteria, answering any questions from students, monitoring progress, and verifying the authenticity of the student's work.
The IB requires three formal interactions between the student and teacher to be recorded on the TOK Essay Planning and Progress Form (TK/PPF). These interactions are evidence for the authenticity of the student's work and also ensure students are provided with an appropriate level of support during the essay-writing process. The TK/PPF is not considered by examiners when determining the final mark, but it will be submitted to the IB along with the essay.
For students who still face any difficulties should consider consulting IB tutors. An IB tutor provides focused help, making tough subjects easier to understand and excel in. Their guidance boosts confidence and exam scores, helping students achieve their academic goals.

IB TOK Essay Assessment Criteria
The TOK Essay is marked out of 10 marks. The marking generally revolves around this question: “Does the student provide a clear, coherent and critical exploration of the essay title?” Below are the main assessment criteria:
- Understanding Knowledge Questions: The essay should demonstrate a sustained focus on relevant knowledge questions, showcasing depth and breadth in understanding. This includes exploring different perspectives and effectively linking these questions to areas of knowledge (AOKs) and ways of knowing (WOKs).
- Quality of Analysis: Students are expected to present clear, coherent, and compelling arguments supported by real-life examples. The analysis should evaluate counterclaims, consider implications, and identify underlying assumptions to provide a balanced discussion.
- Organisation and Coherence: The essay must be well-structured, with a logical flow that enhances the clarity of the argument. Each section should connect seamlessly to the next, ensuring that the discussion remains focused on the prescribed title and knowledge questions.
- Perspectives and Engagement: An excellent essay will show awareness and evaluation of different points of view, reflecting the student's personal engagement with the topic. This involves acknowledging various perspectives, including those arising from cultural, academic, or personal contexts.
- Examples and Real-Life Situations: Effective use of pertinent examples and real-life situations is crucial to illustrate and support arguments. These examples should be well-chosen and integrated into the analysis to enhance the essay's relevance and depth.
For example, here's what a marker would say about a 9 or 10-point essay:
“The discussion has a sustained focus on the title and is linked effectively to areas of knowledge. Arguments are clear, coherent and effectively supported by specific examples. The implications of arguments are considered. There is clear awareness and evaluation of different points of view. The essay is insightful, convincing, accomplished, and lucid”.Use the IB’s TOK Guide for more detail on each of the descriptors for the marking bands.
