WebThe main concept in IRT is the item characteristic curve (ICC). The ICC describes the probability that a person “succeeds” on a given item (individual test question). In the following graph, we can see an ICC for one item intended to measure ability. Notice that the probability of this broadly defined WebThe basic model can take on several forms, depending upon the chosen parameterization and the functional form of the Item Characteristic Curve (ICC). In typical applications, logistic or normal ogive ICC’s are chosen to represent the mathematical form of the ICC.
