Optimal Item Difficulty for the Three-Parameter Normal Ogive Response Model.
Wolfe, John H.
Psychometrika, v46 n4 p461-64 Dec 1981
In tailored testing, it is important to determine the optimal difficulty of the next item to be presented to the examinee. It is shown that the difference that maximizes information for the three-parameter normal ogive response model is greater than the optimal difference for the three-parameter logistic model.
