Abstract : There were six main objectives in the original research proposal, and they can be summarized as follows. (1) Investigation of theory and method for estimating the operating characteristics of discrete item responses, which include the plausibility functions of the distractors of the multiplechoice test item, as well as the graded item responses of the freeresponse test item, without assuming any specific mathematical forms, and without using too many examinees in the whole procedure; (2) Investigation of the various characteristics of the new family of models for the multiplechoice test item, both in theory and in practice; (3) Production and revision of a set of systematic procedures for applying some combinations of a method and an approach for estimating the operating characteristics of discrete item responses, by modifying and reorganizing all the computer programs written for this purpose; (4) Development of latent trait theory further, and include more varieties fo situations; (5) Investigation of ways of bridging across mathematical psychology and cognitive psychology, through latent trait theory; and (6) Systematizing theories and methods to eventually lead to a good introductory book on latent trait theory and other publications.
