Questions chosen for a test should ideally be of moderate difficulty (hence the range of .30 to .70 on the difficulty axis) to differentiate between different levels of student ability effectively. Additionally, they should have a discriminability above .30 to ensure they can distinguish between students who understand the material and those who do not.
