The purpose of this study was to determine the efficiency of the estimates of ability provided by the one-parameter logistic model as compared to the estimates provided by the more general two- and three-parameter models. Several tests were simulated with item parameters meeting the assumptions of either the two- or three-parameter model. For each…

In this paper, an attempt has been made to synthesize some of the current thinking in the area of criterion-referenced testing as well as to provide the beginning of an integration of theory and method for such testing. (Editor)

In light of the widespread use of competency testing, the authors consider that it is important to determine ways of developing and using competency testing to insure that it achieves its full potential. The paper, in three parts, introduces a model for the development and validation of competency tests, reviews several methods for setting…

Technical considerations associated with item selection and reliability assessment are considered in relation to criterion-referenced tests constructed to provide group information. The purpose is to emphasize test building and the evaluation of test scores in program evaluation studies. It is stressed that an evaluator employ a performance or…

A brief history of developments in the assessment of the reliability of credentialing examinations is presented, and some new results are outlined that highlight the interactions among scoring, standard setting, and the reliability and validity of pass-fail decisions. Decision consistency is an important concept in evaluating credentialing…

This instructional training package introduces practitioners to methods for developing, validating, using, and reporting criterion-referenced tests. It provides a comprehensive presentation of criterion-referenced testing technology. The package emphasizes the most recent substantive and technological advances in the field that are both important…
