When students take linear tests online, the default behavior is that each tester will see the questions in the order they appear on the test once it is finalized. The program functions this way to maintain test validity and avoid discriminating against testers with high test anxiety.
The setting Randomize question order for each student during testing allows for the scrambling of questions. This setting will cause students to see the questions in a randomized order. Once students begin testing, this setting cannot be changed.
