A Comparison of the One-, the Modified Three-, and the Three-Parameter Item Response Theory Models in the Test Development Item Selection Process.
Eignor, Daniel R.; Douglass, James B.
This paper attempts to provide some initial information about the use of a variety of item response theory (IRT) models in the item selection process; its purpose is to compare the information curves derived from the selection of items characterized by several different IRT models and their associated parameter estimation programs. These comparisons are made both visually and through the use of relative efficiency curves. Also, it is determined under what conditions (if any) items selected to meet prespecified sets of specifications in forming specially constructed tests, where the items are characterized by BICAL-based one-parameter model item parameter estimates or LOGIST-based modified three-parameter model item parameter estimates, provide as much information as items selected for the specially constructed tests based on LOGIST-based three-parameter model item parameter estimates.
