Abstract
The purpose of this note is twofold: (a) to present the formula for the item information function (IIF) in any direction for the Multidimensional 3-Parameter Logistic (M3-PL) model and (b) to give the equation for the location of maximum item information (theta(max)) in the direction of the item discrimination vector. Several corollaries are given. Implications for future research are discussed.
