This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

The Programme for International Assessment of Adult Competencies (PIAAC) will establish technical standards and guidelines to ensure that the survey design and implementation processes of PIAAC yield high-quality and internationally comparable data. This document provides a revised version of the technical standards and guidelines originally…

Describes performance criteria for users of computer assisted instruction (CAI) that are used to provide users with feedback about their performance relative to other users. This study evaluated 146 novice users on their percentages of correct responses, time required for completion, and number of times the CAI tutorial was performed. (LRW)

Three item response models were evaluated for estimating item parameters and equating test scores. The models, which approximated the traditional three-parameter model, included: (1) the Rasch one-parameter model, operationalized in the BICAL computer program; (2) an approximate three-parameter logistic model based on coarse group data divided…

A multi-purpose, multi-user evaluation system was designed to improve the quality of the reporting of information gathered in testing and evaluation practices. One part of the system, the reporting system for information resulting from a district standardized testing program, was described. The Student-Problem Package software was modified to…
