Knowledge questions (KQs) are at the heart of what we do in TOK. Good KQs should ask second-order questions about the world - in other words, HOW we know, rather than first-order questions, which are concerned with WHAT we know.

We've arranged these KQs in a way that relates to our 5 Big Question framework for TOK, which is our favoured way of structuring the course. There are other ways to structure TOK, such as the Classic structure.
