Theory of knowledge (IB course)
open-in-new
<p>Theory of Knowledge (TOK) is a compulsory <a href="/facts/IB_Diploma_Programme/f1xcyPPt">core subject</a> of the <a href="/facts/IB_Diploma_Programme/f1xcyPPt">International Baccalaureate Diploma Programme</a> covering, for example, <a href="/facts/Epistemology/NsDwpcYH">epistemological</a> topics. It is marked on a letter scale (A-E) and aims to "provide an opportunity for students to reflect on the <a href="/facts/Nature_of_knowledge/hytLblxN">nature of knowledge</a>, and on how we know what we claim to know." Students who attain an E will not be able to receive their final IB Diploma. </p>
