The knower must be able to justify why they believe that p is true. Justification can come in varying degrees and different forms, such as evidence or reasoning. In order to be certain, the knower must be able to provide evidence and reason for why he/she believes the proposition to be true.

According to the theory, Mr. Barker has fulfilled all three conditions necessary to know that there is a student cheating on his test
