The assessment model in theory of knowledge (TOK) comprises two components, an essay and a presentation, both of which should be completed within the 100 hours designated for the course.
The TOK essay: The students write an essay of 1200-1600 words on a title chosen from ten prescribed titles.
The TOK presentation: The students hold an individual presentation of approximately 10 minutes to the class on a relevant topic chosen by the students themselves.
Students are awarded a grade from A-E based on their achievements in TOK. This grade counts towards calculating the awarding of the three extra points in the programme. The exact number of extra points awarded is calculated by using a matrix that takes into account the student results in extended essay and Theory of knowledge.
