The student has effectively addressed the chosen title "Do we need custodians of knowledge? Discuss with reference to two areas of knowledge" by maintaining focus on the title throughout the essay and not including irrelevant information. The essay is well-organized with an introductory paragraph, main body sections, and a concluding paragraph, and it effectively links real-life examples to different Areas of Knowledge, such as Arts and Human Sciences. Additionally, the student demonstrates awareness of different points of view and evaluates them critically, while also considering implications and counterpoints of the arguments. The use of external sources is appropriately acknowledged and referenced, and the essay is predominantly critical and argumentative rather than descriptive, which is suitable for the TOK Essay.
