To set a standard on the "beardedness" test (see TM 507 062) the probability that a student with a specific score will be judged as bearded must be estimated for each test score. To get an unbiased estimate of that probability, a representative sample of students at each test score level must be chosen. (BW)

An empirical item characteristic curve shows the probability of a correct response as a function of the student's total test score. These curves can be estimated from large-scale pretest data. They enable test developers to select items that discriminate well in the score region where decisions are made. A similar set of curves can be used to…
