Have a pool of questions for each standard on a topic test so that multiple versions could be made.

Having a bank of questions for each standard in a topic assessment would allow for multiple versions of a test. This is important for students who have to retake a test so they don't get the exact same question, but the same standard being tested. This is also useful when a teacher has multiple sections of the same course so not all students have the exact same questions and there is randomization of test contents.
